Crittercism: Android Apps Crash Less Often Than iOS Apps [u]


Apple’s iOS 7.1 may have the fewest crashes, but Android apps are more stable, according to the latest report issued by Crittericism (via Fortune).

The report, entitled “Mobile Experience Benchmark“, was published by the San Francisco–based performance analytics company on Thursday and shares important details about mobile performance. What they have found, after tracking about a billion users for a month, is that 47% of apps have an uptime that is not competitive, as they crash more than 1% of the time. To stay competitive, an app should have a crash rate of less than 1%.

When highlighting app performance on mobile operating systems, Crittercism has found that Gingerbread apps are the least stable, which could make sense, as the OS is four years old now. However, Samsung’s devices ranked as the most stable phones and tablets.

Ios apps

iOS 7.1, on the other hand, has the lowest crash rate, with the iPhone 5 crashing the least. An interesting highlight of the report is that apps on iPhones are more stable than those on iPads. Now, iOS 6 crashed 2.5% of the time; iOS 7.0, 2.1%; and iOS 7.1, 1.6%.

Android apps

This compares to Android crash rates as follows: KitKat, Ice Cream Sandwich, and Jelly Bean crashed 0.7% of the time; and Gingerbread, 1.7%. In other words, Android apps are more stable than iOS apps.

A similar report was published by Crittercism after the iPhone 5s launched, claiming that the handset’s hardware causes twice as many app crashes as the iPhone 5c.

What’s your experience?

Update: I an email sent to iPhoneinCanada, Josh van Tonder cleared a couple vague points of the Crittercism report.

IIC: Crittercism is funded through Google Ventures. How does that affect your reports?

Josh van Tonder: Crittercism operates independently from Google. Google Ventures is financed by Google but operates independently and does not make strategic investments for Google. In addition to Google Ventures, Crittercism also had ex-Opus Capital general partner, Bob Borchers, on our board. While at Apple, Bob helped bring the Apple iPhone to market.

IIC: What does crash/crash rate mean?

Josh van Tonder: Crash rate is defined as the percentage of app loads that result in an app crashing. All app loads and crashes of an app are counted but only for apps that Crittercism monitors.

IIC: Where does Crittercism collect this data from?

Josh van Tonder: Crittercism offers a hosted mobile application performance solution for companies that have mobile apps. These companies build Crittercism into the apps that they distribute so that they can deliver better performing apps for their users. We monitor tens of thousands of apps that together have over one billion users. Crittercism then collects anonymized diagnostic information from these apps for companies to monitor, troubleshoot, and trend the performance of their mobile apps. The report aggregates statistics across this anonymized diagnostic data.

    Some things are wrong with this…

    1. Crittercism is funded by Google.

    2. It jumps around between suggesting the hardware is responsible, and/or the OS is responsible, and/or when the Cloud is involved, and/or when other services are involved, and/or the apps themselves are responsible. Yes, any can be at fault, but an exceedingly high percentage of the time it is a buggy app that causes the crash. So the platform is irrelevant. It’s almost always the poorly tested app that is at fault.

    3. “Crash” is a misnomer (although I don’t think anyone cares about that anymore). But the actual report says “App Uptime (Crash)”… What?! … I think it’s because they had limited space in the column, so they didn’t want to get descriptive – so they expected people to understand that “crash” (by their way of thinking) actually meant the opposite of uptime. Seems a bit juvenile (unprofessional) to me.

    4. I’m curious how they got access to 1 billion users. I’m also curious how each user actually experienced 3+ crashes per day (if I read it right).

    5. Are they counting situations where the same app crashes at the same point?

    We’ve contacted Crittercism and will update the post if we hear back… Hope this helps, Al.

  • T_T ?

    I am inclined to agree. In the past I would say Android has more crashes. However, with Kit Kat it’s not very common. But it still happens. In upgrading to IOS 7.1 I am now getting a LOT of crashes with the iPhone 5.

    Uh yeah…. This is true if you own an iPad 1 (iOS 6) and a Nexus 5 (KitKat) like myself.

    Crashes are everywhere, nothing is crash free. Not even stocked apps. Just reset and rebuilt your device again.

    It just works.

    Hi Al, post updated.

  • Al

    Surprising answers they gave. Kind-of begs even more questions… some rather serious, involving excess data usage and if such data collection is authorized by the user or done without permission.

    It’s clear that the results are skewed to specific apps and not an unrestricted cross-section. Whether or not that keeps things equal is difficult to say since some of their clients may be more prominent in one OS than another.

    Anyway, thanks for the follow-up István!

    I hoped on a ipad for the first time last week after useing android tablets, the first thing it did after a few mins was crash out of that silly safari app! I said what was that it just went back to the main screen. I was told it does that now and again! I want be buying an over rated idevice anytime soon!
