Quick answer: Crashlytics is the free default for iOS and Android and hard to beat for a mobile-only game. Add Bugnet if you want players to report bugs from inside the game, Play Store and App Store reviews turned into bug reports, and coverage for the PC or web version too. Sentry and BugSnag suit studios that also monitor apps and services. Luciq (formerly Instabug) targets native and cross-platform apps rather than game engines.
Mobile developers have the widest choice of crash reporters, because mobile apps have been the core market for error monitoring for a decade. That is also the catch: most of these tools think in terms of app screens and network calls, not scenes, frame rates and players who rate you one star instead of filing a report. Here is how they compare for mobile games, from each vendor's published information as of October 2026.

Firebase Crashlytics
Free, mature and well integrated with Firebase. For a Unity mobile game it captures C# exceptions and native crashes on iOS and Android with custom keys and logs. If your game is mobile-only and you already use Firebase, start here. It does not cover desktop or web builds in production.
Bugnet
Bugnet adds what mobile crash tools do not: an in-game report form for the bugs that do not crash (put a “Report a bug” button in your pause menu), Google Play and App Store reviews imported every hour with device and OS details, one- and two-star reviews that describe a bug filed as reports automatically, and public replies from the dashboard. Its SDKs cover Unity, Godot, Unreal, GameMaker and Construct 3 mobile builds, with crashes and reports in one tracker. Many mobile teams run it alongside Crashlytics. See turning Google Play reviews into bug reports. Free to start.
Sentry and BugSnag
Both are mature, app-oriented monitors with mobile SDKs and Unity support. Sentry's Unity SDK adds ANR detection and a feedback prefab; BugSnag's Unity notifier is fully supported on Android and iOS. Both price by volume, which can bite a free-to-play game with a big install base. Pick one if your studio also runs apps or services on it.
Unity Diagnostics
For Unity 6.2 and later, the built-in Diagnostics service reports crashes, exceptions and Android ANRs (Android 11+) in the Unity Dashboard. Older projects need an engine upgrade. See Unity Diagnostics vs Crashlytics.
Backtrace and Luciq
Backtrace is a heavyweight native crash platform with a mobile-only seat at $600 per user per year. Luciq (formerly Instabug) is excellent for native and cross-platform mobile apps, with bug reporting, crash reporting and session replay, but its listed SDKs are iOS, Android, React Native and Flutter, not game engines. See Instabug alternative for game developers.
A note on App Center
If your mobile game still uses Visual Studio App Center for crashes, its Diagnostics support ends at the end of March 2027. See App Center crash reporting alternatives.
Recommendations
- Mobile-only Unity game, tight budget: Crashlytics, plus Bugnet for player reports and store reviews.
- Mobile plus a PC or web version: Bugnet (or Sentry) so every platform reports to one place.
- Studio with apps and services on Sentry or BugSnag: keep it, and add player reporting.
Frequently asked questions
What is the best crash reporter for mobile games?
For a mobile-only game, Firebase Crashlytics is free and mature. For in-game bug reports, store review monitoring and coverage of PC or web versions, Bugnet is the best complement or replacement. Sentry and BugSnag suit studios that also monitor apps and services.
Is Crashlytics free?
Yes. Firebase Crashlytics is free.
Can I turn Google Play and App Store reviews into bug reports?
Yes. Bugnet imports Google Play and App Store reviews every hour and can file one- and two-star reviews that describe a bug as bug reports, with the device and OS details from the review.
Does Instabug or Luciq support Unity games?
Luciq lists SDKs for native iOS, native Android, React Native and Flutter. Unity, Unreal and Godot are not among its listed platforms.
How do players report bugs in a mobile game?
Add a Report a bug button to the pause or settings menu that opens an in-game form. Bugnet provides one for Unity, Godot, GameMaker and Construct 3, and Unreal games call its report function from their own UI.
On mobile, the one-star review is the bug report you did not ask for. Give players a better button.
