  • Study Claims iOS Apps Crash More Often Than Android Apps

    [SIZE=1]Number of app crashes by percentage.[/SIZE]

    A recent report (represented graphically above) by crash analysis firm Crittercism claims iOS apps crash more often than Android Apps. But, the results aren't exactly "cut and dry."

    Critiercismís chart showing the total percentage of app crashes based on iOS and version number clearly shows iOS has more app crashes than Android. The data has been normalized so the numbers arenít statistically irrelevant (we presume), especially since they analyzed 215 million app crashes across the two platforms (the number of iOS apps used outnumbered Android 3-1, but again the data was normalized preventing a bias).

    However, the reason behind the rise in iOS app crashes according to Crittercism is Appleís recent release of iOS 5.0 and iOS 5.0.1. Major updates like iOS 5.0 by their nature create more problems and incompatibilities. Running newer apps on older hardware is always a recipe for disasters. This coupled with the fact the latest version of Android hasnít arrived likely created a sizable difference in app crashes. TUAW posits that iOS users tax their phones more than other mobile users, causing iOS apps to eat up memory and crash. TUAW points out that these are just app crashes and not iOS crashes either. Killing background processes and freeing up space usually fix this problem.

    Also, Iíd venture a guess that Appleís frequent small updates to iOS (Android users arenít afforded such luxuries) adds to the number of app crashes. It seems like simply managing the number of apps running at a time and freeing system resources would eliminate most app crashes (manually or via any app-management application). Honestly, Iíd take Apple frequent minor updates and scheduled major updates over the haphazard release of Android updates across devices and carriers.

    An interesting follow-up study should examine the number of system crashes, and the percentage of apps each user-base is running at a time on average.

      I have at least 2-3 crashes of apps that leave me staring at my homescreen. Most notably is the iOS settings app, which has a tendency to crap out when going into the General or Wifi sections, or if the app was backgrounded previously.

      I see less app crashes on my pre-alpha CM9 build for my Galaxy Tab 10.1 than I saw even on a stock iOS 5.0.1. The modmyi app is notoriously bad, and what makes it worse is that I can't even use tapatalk app instead, which is infinitely more stable.

      Since I upgraded to 5.0.1 it has crashed once every other day, Facebook cause the thing to crash every time I open certain high rez picture. My iPad2 crashes just as often as my iPhone.
      So that figure is fairly accurate comparing the crash rate of my current iOS and previous ones (since 4.1)

      Its getting really annoying the amount of crashes ive seen now. Usually happens when im running a music app in the background.

      To this day I've completed about 5 missions in GTA, which I might add took a lot of patience (and constant recharging lmao!) I dont even play it anymore. Since the last update it's gotten ridiculous, now its like every app has a mind of its own. *Lmao just crashed typing this!!*

      Hmm I run zero apps in the background when twitter, ModMyi, and Safari crash. I think they're just badly coded honestly. Twitter crashes after using it for a while, no matter what you're actually doing with it. There's obviously some memory leaks there. Safari crashes are the site's fault most of the time, but it crashes when zooming a lot.

      When my iOS apps crash, it normally resumes where I left off. I really haven't noticed before, but 5.0 does seem to crash more than 4.0 or prior. It's still not enough to really complain about. It's not like it freezes the entire phone or shuts the phone off.

      I think there may be something wrong with Apples upgrade path to iOS 5. The only way i was able to get it stable on all my devices is by putting the devices in DFU mode first and THEN doing a iOS restore with restoring any backups. They not have great battery life once again and have not seen any crashes.

      Try the DFU mode restore without any backup restore after. I had a lot of problems myself and it seemed to have fixed them on both my work and home iPad2 and my iPhone 4.

      Here is the problem with this study: Too. Many. Variables. They are saying that they used a multitude of Android phones and iOS devices. No word on how many of these devices were rooted or not. There is no mention of what apps the code is in, or how many apps the user has running. If they had some sort of controls, this would have some weight. Example: If they studied 1000 iPhone 4S's and 1000 Galaxy S II's, either all rooted or not, with a specific number of apps open at the same time, and using the same app with equivalent code (Since iOS and Android use different languages). This may sound unrealistic, but it is the only way (that I see) where we could get more believable results. I cannot speak to how often apps crash on Android, but on my iPad, I do experience crashes like daily. That said, I have many MobileSubstrate and other types of tweaks installed and understand that it comes with the territory (due to the low amount of RAM in the iPad1). When I tune into "Safe Mode", I notice almost no crashes, hence my theory of the heavy load with the tweaks.

      I'd like to mention that my problem with this study is not that it favors Android. My personal opinion is to each his own as far as the mobile OS debate is concerned. I don't want to come across as a politician that is trying to discredit his peers lol.

      TL;DR: This study says almost nothing, at least in the sense of some sort of control and accuracy.

      Thats no surprise that IOS is the worst for crashes.

      I put 99% of crashes down to Mobile Substrate.
      I've done some tests on the iPad1 and a lot of apps work fine UNTIL MS is installed then they either dont load or crash all the time.
      Thats 1 reason when everything is forcing MS to be installed all it is doing is forcing you to accept the crashes that come with MS which REALLY SUCKS.
      a few things DONT need MS so WHY is it even needed? I think the app devs should have a look at their apps and if MS is not needed then remove the need for it then the iPhone will be a lot more stable.

      Every morning I wake up, when I launch the Facebook app, it always seems to crash only on that time of the day. Weird.

      I have to say, as a developer, Crashes occur when the app comes across something impossible to handle, or when its data is tampered with. Additionally, apps crash when something is taken out of memory twice, and such a condition can be the result of some rare event.

      I also would like to mention that with each update, iOS changes enough to crash most apps...

      Seriously, i am very surprised by these results, and everyone's responses. I have a iPhone 4s, running 5.0.1 jailbroken, and it is very rare that I have a app crash. Maybe one every few days....

      And it's not like it's a big deal when a app does crash, not even a inconvenience really. I close the app, and reopen it....it's almost the equivalent of just pressing the home button, then reopening whatever app i was using. It's not like I have to sit there and wait for it to respond for minutes, then have to restart the device (like a PC crash). Not a big deal at all....in my opinion.

      Thats why Apple need to smarten up and realise Cydia and jailbreaking arn't going anywhere and to stop fighting against them.

      They (Apple) are the ones causing all the crashes and not just for cydia apps but also appstore apps.

      And they are getting as bad as $ony as every update something useful gets removed. EG: Ipad and USB devices, AirPrint, AirPlay, stability and the list goes on...

      Thats why Android phones are better than iPhones. They work like you want them to work.

      Facebook for iOS is the WORST. If its not crashing, then I'm sitting there staring at it forever waiting for it to load data. Messages are borderline unusable most of the time. To make matters worse, the mobile site for Safari is buggy as hell too, and often loads a totally blank and unresponsive screen.. So I have to either use alternate apps or fake my browser into thinking I'm using a desktop computer. You'd think of all things that Facebook would have some polish by now.

      I haven't had any issues. Facebook sucks on mobile... but then again, Facebook sucks equally as bad if not worse on Android - CM7.

      iPhone 4 iOS 5.0.1 - tons of jb tweaks, etc. No crashes here! Zephyr will occasionally cease functionality, but other than that I have zero problems.

      Don't download memory-intensive crapapps!

      if apple is gonna release a software update it needs to be stable they still cant figure out all the problems with the battery its sad
