I'm currently looking for a way to track user activity. I'm working on an IOS app using swift and i need stats of apps usage. basically I want to get-make a tracking of the used apps. Data like opened apps, start time and shut down time... I know that for get all stats, maybe is necessary run a backgroud service, but, this is another problem that i think to solve after. for now i want to know if it's posible, if there is some way to get stats for used apps. I know that the UIApplication class call the UIApplicationMain function when an app is launched. Maybe, from my app, there is a way for access this info?... Thanks, i have been a long time reading but really, i can't see some clear option.
If (as David has interpreted your question in the comments) you are trying to track usage of other apps that aren't yours, he's right; you can only track your own app's usage.
If you are needing to track events in your own app, there are a good number of analytic frameworks available to do exactly what you are needing to do.
Flurry is one I've used in the past with success, and is one of the more well know solutions. I've also utilized Google's analytics framework. Both are pretty straightforward to integrate into your app and to track the sort of fine grained events you are looking to capture. You can't go wrong with either one of those.
Here is a (slightly old) list of additional tracking/analytics options beyond Flurry and Google's offerings.
You can record your feedback and user experiences, and bug reports with lookback.io
Is there a framework that will allow to create web apps for iOS that will run as smoothly as native app?
I've checked demos of Sencha Touch http://www.sencha.com/products/touch on my iPad there's visible delay for touch events and for how precisely they are recognized. The feeling isn't the same as for native apps.
Is there other frameworks or technics that will allow to provide same experience as native apps?
It depends on your app. If your app is a hard-core heavy-duty 3D game, then no. If your app is primarily displaying static content ... like a web page or collection of photos, you might get close enough.
Think about what experience you want to achieve first. If you want a cross platform application and you want to avoid the stores (App Store, Google Play, BB App World), then by all means, consider a web app.
Other things to consider, how much data do you estimate the user will need store locally (HTML apps are more limited in this respect); how much functionality is lost when there is no network connection, and does this loss of functionality make the app unusable.
Like the answer by #RichardTurner, if you need the kind of performance you find in the higher end games (Infinity Blade or Modern Combat 3), then native is the way to go.
Figure what you want, then you will have better idea of what technology to use.
NO. Native apps will perform better every single time over web apps. If you want a smooth experience, go native. Also consider that some people have older model iOS devices and performance will be even more difficult to achieve on those devices in web apps.
Here are a few things to consider with a Sencha app vs a native application.
You were browsing a Sencha Touch application online and chances are it wasn't a "packaged" version so you would have to download each source file individually.
With Sencha, you can utilize Sencha CMD to package an application which essentially builds a single minified js file containing only the required components from the Sencha library and your application (smaller DOM). You can also look into a production version which takes advantage of appcache. You'll see some performance increases here.
A packaged native Touch application will contain the actual JS, CSS, etc. files as part of the applications source, so their is no downloading from external resources.
You have to consider that any HTML5 application is going to have a ~300ms touch delay, more on that here: http://updates.html5rocks.com/2013/12/300ms-tap-delay-gone-away
I recently started trying to develop apps using titanium.
When i ran one basic app containing two table views and some static data, it showed me 80 memory leaks and about 15 warnings - i think coming from the frameworks.
As an iOS developer, i'm used to seeing less than 5 memory leaks in complex apps too.
So, I'd like to know whether applications are getting accepted by apple when developed through titanium.
Also, I'd like to know whether,looking at the state of the titanium frameworks,its worth learning it right now.
Thanks in advance!
Your First Question, Yes! they are being accepted by Apple App Store.
And For your second question, its relative to likings of individual. I started mobile application development with titanium, but soon I realized that there is no better way to create an application then to create it natively. I would say if the applications you are developing are not scaled at enterprise level magnitude (means thousands of lines of code), better develop apps natively.
Titanium is increasing support and improving frameworks rapidly, its also reduces lines of code by third! and the best thing about it is, its cross-platform! but to my personal liking i always prefer native development. The power, the iOS gives you, Titanium wont!
One more thing i would like to add, despite all, you should learn it! :)

I wonder if I were to develop a mobile Web app (now, in two weeks, or in a month), which one should I go for? Which one would you mobile Web developers go for?
If jQM 1.0 were officially released today, I would most likely embrace it (as long as it actually delivers what it promises). Now that it is in alpha, I wonder whether it is worth to jump into it yet for a commercial grade project? Would Sencha Touch be a better alternative?
Sencha Touch is an application framework (you create your interface programmatically through Javascript) while jQuery Mobile is more of a mobile enhancement library (you write regular HTML for your content, then add jQuery mobile for transitions/animations). jQuery Mobile has an easier learning curve, but Sencha Touch can better simulate "native" apps.
The first question you need to ask yourself is what is the purpose of the application. If you want to release an application for sales on one of the retail outlets (iTunes, Andoid App store), or you need access to device specific functions that are not accessible via local APIs yet (accelerometer, camera, contacts, etc) then you should be thinking Native or one of the hybrid solutions (Appcelerator, PhoneGap, etc.).
If your audience is going to be more in the "mobile web" space, such as a mobile version of a corporate web desktop site, or intranet web application port, then you should be looking at Sencha Touch and jQuery Mobile. The decision between those two is really going to be based on you development experience and and what you feel more comfortable with. Sencha Touch is a VERY robust platform that has a Desktop (ExtJS) and mobile (Sencha Touch) that mirror each other so knowing one pretty much allows you to get up and running with the other. Also, Sencha has moved to an MVC model on the client which really helps to organize client side code and make it much more congruent with server-side development platforms.
The post above is actually incorrect, using the MVC pattern on the client combined with the historyUrl on your dispatch commands gives you the ability to use the browser back and forward buttons of the browser, so that is not exclusive to jQuery Mobile. Also, the Sencha Team's suite of products includes a Designer application that provides Designer which is a WYSIWYG editor that allows for the drag and drog creation of UIs. This company's roadmap has them in the process of updating the Designer app to allow for the drag and drop design of Touch mobile screens and application that will function with the MVC pattern. They are also getting ready to release a new version of the Sencha Command tool that will automatically generate entire MVC application structures for you in a matter of minutes, which you can then add the necessary custom code to round out your application. Lastly, the new SASS theming capabilities allow designers to use CSS3 and SASS config files along with variables and Mixins to generate cross-browser CSS style sheets for your application.
So, the decision of which way to go for the mobile web development question comes down to how comfortable you are with object oriented javascript. If you are very comfortable with it, then Sencha Touch is the way to go as it very extensible class system built into the core engine that can be customized to your hearts content...but if you have minimal experience with JS and you want the server to deliver your UI and don't mind seeing the Address bar drop down to move between pages (less web 2.0 looking), then jQueryMobile is the way to go.
It's pretty obvious that I am biased to Sencha Touch due to its well thought out class structure, extensibility, very active user community, web/mobile continuity, and constant improvement to the core framework and new tools that simplify development efforts. And not to mention that the Touch platform is more mature as jQM has not reached production mode yet.
I've been using jQuery mobile for a while now. It works well under Blackberry 6, iPhone, and Android.
I wrote an article about it here: jQuery mobile alpha
Though it's alpha, they are showing good progress. I've been looking into their development in github, seems like there's going to be cool stuff by early 2011.
UPDATE 2011-12-01 jQuery Mobile relased version 1.0, finally out of alpha. Read more about it here: http://jquerymobile.com/blog/2011/11/16/announcing-jquery-mobile-1-0/
If you're going to make a mobile version of a website, I am going to use jQuery Mobile. If you're going to make a “native” mobile application, I will be more likely use Sencha Touch.
http://tysonlloydcadenhead.com/blog/jquery-mobile-vs-sencha-touch
Sencha touch has lived longer than jquerymobile but I found that jquerymobile handles device back button much better than SenchaTouch.
I always consider back/history button handling is important in my apps, so I prefer jquerymobile.
I always consider myself a JavaScript programmer, but I like the fact that I rarely need to to type any JavaScript code when I use jquerymobile.
jquerymobile design is brilliant IMHO.
I am also in favor of sencha, JQM is really slow and failed to give an impression of an native app.
Praveen
why limit yourself...
Look into PhoneGap and Titanium Appcelerator
the make the comparison based on what you are trying to accomplish. I know Sencha Touch has a licensing fee and like you said jQM is not officially released yet.
This is a great time to be in the mobile space because there are so many viable options
I think jQuery mobile is easier to learn and seems to be very promising. Version 1.0 is not yet available, but its going to be a good product. I find it very attractive because it is based on jQuery - simplicity is the motto
Don't forget that there is also Dojo Toolkit Mobile. It looks nice, at least at first look and it is built on top of the proven and solid Dojo Toolkit core. http://dojotoolkit.org/features/mobile.
The Dojo Toolkit don't get too much audience recently but it looks like they made a lot of progress from the times it was a bit heavy, I think it is worth looking at it.
I've been trying out the sencha architect and to be honest ithas been a nightmare to get running.
My background is DotNet, html, javascript, VB, java and have been using eclipse etc for a while so am not a huge newbie with figuring out dependencys etc.
Here is what I have struck:
I went to the Sench site, downloaded Architect.
It then got me to download toolkit and sencha touch. I downlaoded exactly what was recommend / instructed by the help files / site.
I have Sencha Architect V2.1.0 Build 584., sencha-touch-2.0.1.1-commercial.zip, SenchaSDKTools-2.0.0-beta3-windows.exe
I also downloaded and installed a new java sdk / run time etc. The install has been done on a dead clean XP box (vmware). Web server is xampp.
Sencha does not recognise the SenchaSDKTools-2.0.0-beta3. You have to hack it using hard to find instructions. Even after hacking it the architect fails to use the proper SDK and gives error messages on deployment.
There have also been numerous errors to figure out along the way and issues where data just wont load even having followed instructions to the letter.
I have spent 11 hours getting to the point where the application will run properly without whinging but it wont deploy. It is bad enough learning a new tool / framework etc without the ide causing grief and the "instructional demos" leading you up the path.
There are lots of people getting the same errors all over.
After 15 hours of effort I am giving it up as a bad job and am returning to IBM XPages / PHP and Blueprint CSS with old fashioned, hand coded html5 / CSS3 and jquery / Ajax / JSon apps.
My reason for doing this: Application Architect keeps pushing you back to the command line. I love the command line, give me a bash shell and vi and I'm good to go. However for complex, multi file deplyoments such as mobile apps a good IDE is worth its weight in gold. Architect is not there yet. I keep needing to lift the hood and hack to get things working.
I originally looked at Sencha for a 12 year old who is interested in mobile apps and is looking for an ide to use. I tried it out - it is not suitable - even getting a hello world type app running is going to be too much for a newbie and the first app in the help files doesnt explain itself but has you copying code for pulling data from a web site you have to sign up for. (ccitybars app).
A big improvement for sencha will be when Architect works out of the box (possibly an installer with sdk, tools , touch and architect all in one) and the fisrt app -walk through is a simple hello world that then builds to entering data, saving data and then displaying data before going multi form.
I was faced with the same choice about half a year ago, then went for jQTouch instead of Sencha Touch, which I found to be extremely Javascript centered. I'm currently working on a port of that same project to jQuery Mobile and I think the transition will be much smoother than it would have been with a Sencha Touch project.
If you know basic PHP I strongly suggest jqmphp.com. Up and running in less than 3 days a whole online mobile based site to order food!
MoSync team has recently done an interesting comparison:
Which Mobile JavaScript framework is the best: jQuery Mobile, Sencha Touch, jQtouch, or Kendo UI?

http://www.codefessions.com/2012/04/which-mobile-javascript-framework-is.html
http://www.codefessions.com/2012/05/which-mobile-javascript-framework-is.html
jQueryMobile wins but huge boost in arm is because of licensing. I prefer jQueryMobile because I don't want someone(thing) else to write my markup, that way hacking becoming difficult (at least for me), however, I do have couple of HTML5 apps under my belt now, one each in jQM and Sencha Touch. Sencha Touch makes it smoother, very hard to learn though while jQM gets you started in a day, there are bug but you usually get around them because of amazing web community around this framework.
I've built a nice production app in a few days using Sencha Touch 2.0 and it's delivering as documented. And, it's FAST. There might be some bugs, but, when I've run into one (which, is rarely), there seemed to be many ways to approach a solution so that it's really not that relevant.
Sencha Touch looks great but it is difficult to use. The Sencha support forums offer minimal support. Sencha Touch 2.x is still in alpha is quite buggy
Sencha touch will be the best option is you are just starting because it is well documented and it has a community support. Also, with phonegap, you spend more time on the development and less on things about other mobile platforms. Phonegap will build the application for you , once you upload it to the builder .
Comparing the two is like comparing apples and grapes...though you want to develop mobile apps with both, the level of comfort with either depends entirely on you.
This chart might be helpful if you want to compare the features : http://www.markus-falk.com/mobile-frameworks-comparison-chart/
Sencha Touch based apps can only work on WebKit based browsers. JQueryMobile based apps can work on all mobile web browsers.
I think you can go ahead with JQueryMobile for next 2 to 3 years. I am expecting in 2-3 years all mobile browsers will be based on WebKit engine. Once all mobile browsers start supporting WebKit, move to the Sench Touch mainly because of very good quality user interface.
I suggest KendoUI
It is unbeatable and fast performance in a training of couple of days. Not to mention the fast update and new features and support for server side wrappers (asp.net, php, jsp). It is unique!
I have used both and they each have conditions where one is better suited then the other.
In my opinion you would use JQueryMobile when
1. You need a quick and light weight mobile implementation of an web application.
2. You have time constraints (definitely faster to learn and implement then Sencha Touch).
3. Native look and feel is not a requirement.
When making an extension to an existing web application where relatively simple functionalities have to be extended to extended to mobile (really fast and easy) I found JQM to be extremely useful and straight forward.
In my opinion you would use sencha when
1. You want a native look and feel
2. You want a higher degree of functionality on the mobile side (possible access to native api's through phone gap)
3. Targeting the latest smartphones (performance is impressive)
What is the best iPhone analytics offering out there? I've seen Pinchmedia but I'm not sure about it since the default application page says "Last Updated July 2008".
Nowadays Pinch Media has been merged into Flurry. Flurry is a decent choice.
If this is a quick project 'afterthought' you'll be pleased to know that basic Flurry integration is a one liner in the AppDelegate :)
I've tried several packages and Pinch Media is by far the best. I don't know where that July 2008 date comes from, they've been releasing updates regularly and are super-responsive to feedback and questions emailed to their support people. Whether by coincidence or not, several of my suggestions have made it into the current Pinch libraries
Aside from the excellent support, the reason I prefer pinch is that they seemed to be the only package that updates several times a day - usually once per hour. This is great if you're trying new advertising techniques, or just like obsessing over your sales figures (as every developer does at first :)
On the downside there are two issues I have with Pinch - their website can be a little clunky and isn't very iPhone friendly (ironic!), and at times they've had problems where stat updates aren't available due to hardware problems. I also wish they had an "overview" for all your applications.
It's worth pointing out that all of the analytics libraries are extremely easy to build into your application and all work with both the simulator and hardware so it's extremely easy to evaluate them to find the one you like best. It's even possible to use several at once - though I would only do this for testing.
Google :)
http://code.google.com/intl/fr-FR/apis/analytics/docs/tracking/mobileAppsTracking.html
Flurry is a very nice option. In my most recent app I have tried Appsee Mobile Analytics which I like if you're looking for something different - they give you video recordings of user sessions and heat maps. It's a little more interactive than other analytics
If you are interested in visual analytic tools, like heatmaps, or you want to get some inside on the way that your users use your app you should try heatma.ps
Quantcast, who is well know for audience demographics measurement for websites, launched it's Quantcast Measure for Mobile Apps program earlier this year. Their iOS, Android, and PhoneGap SDK is available on github.
At this point you may well want to roll your own - on a constrained device do you really want a third party library taking up an unknown amount of limited network bandwidth and processing power?
