What are the best practices for tracking crash-free rate?

Track it from real player data, break it down per version, watch the trend, and use it to drive fixing high-impact crashes. Track crash-free rate (the share of sessions or players without a crash) from real player data in the field rather than your own testing, since the metric is meaningful only as a measure of what players actually experience, including on the devices and conditions you can't replicate. Break it down per version so a regression, a new build with a worse crash-free rate, shows up against the previous build, since a blended overall rate hides per-build stability. Watch the trend over time so you can see whether your stability is improving or degrading, which tells you whether your stability efforts are working. And use the crash-free rate to drive action, fix the high-impact crashes (the ones dragging your rate down most) first, since the rate tells you how you're doing while the high-impact crashes (ranked by affected players) tell you what to fix to improve it. Crash-free rate is the clearest single stability metric, so the practices serve tracking it meaningfully (from real player data), making it actionable (per version, trended), and using it to guide your stability work (driving fixes of the high-impact crashes). The metric is most valuable not as a number to report but as a tool: it measures your real stability, catches regressions (per version), shows your direction (trend), and, combined with crashes ranked by impact, guides you to the fixes that will most raise it. Capturing crashes from the field (since most players don't report) is what makes accurate real-player crash-free rate tracking possible, and grouping and ranking crashes by affected players is what lets you target the high-impact crashes to improve the rate.

What is crash-free rate and why does it matter?

Crash-free rate is the share of sessions (or players) that don't experience a crash, for example, a 99% crash-free session rate means 99% of play sessions complete without crashing, and it matters because it's the clearest single measure of your game's stability, directly capturing how reliably the game works for players. It matters for several reasons. First, it directly reflects player experience: a higher crash-free rate means fewer players hit crashes, which means less of the frustration, churn, and bad reviews that crashes drive, so the rate is closely tied to the outcomes you care about (retention, reviews, reputation). Second, it's a single, comparable number that summarizes stability, making it easy to track over time and across versions, you can see at a glance whether your game is stable and whether it's getting better or worse. Third, tracked per version, it catches regressions (a new build with a lower crash-free rate has regressed) and lets you verify that fixes improve stability (the rate should rise as you fix crashes). Fourth, it gives you a target to improve: you can work to raise your crash-free rate by fixing the high-impact crashes dragging it down. So crash-free rate matters as the foundational stability metric, it measures how reliably your game works for players (the essence of stability), in a single trackable number that ties to player outcomes, catches regressions per version, and guides your stability work. To be meaningful, it must be measured from real player data in the field (so it reflects actual player experience, not your best-case testing), which requires capturing crashes from the field since most players don't report. Tracking your crash-free rate, from real player data, per version, over time, and using it to drive fixing the high-impact crashes, is therefore central to managing and improving your game's stability, because it tells you your true stability and whether your efforts are improving it, which is exactly what you need to keep your game reliable for players. It's the metric that answers 'how stable is my game for the people playing it,' which is the question that matters for the player experience and the outcomes that depend on stability.

How do I improve my crash-free rate?

Capture crashes from the field, fix the high-impact ones dragging your rate down, verify the fixes, and prevent regressions, while tracking the rate per version to confirm it's improving. The crash-free rate is lowered by the crashes players hit, and since crash volume is concentrated (a handful of issues cause most crashes), the way to improve the rate most is to fix the high-impact crashes, the ones affecting the most players, which drag the rate down most. So: capture crashes automatically from the field (so you see all of them, including the majority players don't report, with the context to fix them), group them by signature and rank by affected players (so you can identify the high-impact crashes most responsible for your crash-free rate, the ones to fix first), fix those at the root (which, because volume is concentrated, removes most of your crashes and raises your rate most), verify the fixes worked (confirm the crashes stopped on the fixed version, so the rate improvement is real), and prevent regressions (track crash-free rate per version so a future update that reintroduces crashes and lowers the rate is caught, keeping your improvement from drifting back). Track your crash-free rate per version throughout, so you can confirm it's actually rising as you fix crashes (the rate should improve on builds that fix high-impact crashes) and catch any regressions that would lower it. This is the same loop as reducing crashes generally, capture, prioritize by impact, fix, verify, prevent regressions, since improving crash-free rate is improving stability, and the rate is just the measure of it. The key efficiency is targeting the high-impact crashes: because crash volume is concentrated, fixing the few crashes affecting the most players delivers the biggest crash-free rate improvement for the least effort, whereas chasing rare crashes barely moves the rate. So you improve your crash-free rate by capturing crashes from the field, fixing the high-impact ones (ranked by affected players) at the root, verifying, and preventing regressions, with per-version tracking confirming the rate rises and catching regressions, which steadily raises the share of players who never hit a crash, the meaning of a higher crash-free rate. Tracking the rate per version is what lets you see this improvement and ensure it sticks, closing the loop between measuring stability (the crash-free rate) and improving it (fixing the high-impact crashes that drive it).

Best Practices for Tracking Your Crash-Free Rate

Quick answer: Track crash-free rate from real player data, break it down per version, watch the trend, and use it to drive fixing the high-impact crashes. Crash-free rate is the clearest single stability metric.

Crash-free rate, the share of sessions or players without a crash, is the clearest single measure of your game's stability. Here are the best practices for tracking your crash-free rate.

Track It From Real Player Data

Crash-free rate only means something if it reflects real players, so track it from real player data in the field, not your own testing. Real-data crash-free rate tells you your actual stability for players, including on the devices and conditions you can't replicate.

Bugnet captures crashes from real players, so crash-free rate reflects real stability. Tracking crash-free rate from real player data is the foundation, since the metric is meaningful only as a measure of what players actually experience.

Break It Down Per Version and Watch the Trend

Track crash-free rate per version (so a regression, a new build with a worse rate, shows) and watch the trend over time (so you see whether stability is improving or degrading). Per-version and trend views make crash-free rate actionable rather than a static number.

Bugnet tracks crash rate per version over time, so per-version crash-free rate and trends are clear. Breaking crash-free rate down per version and watching the trend turn it into a tool for catching regressions and seeing your stability direction.

Use It to Drive Fixing the High-Impact Crashes

Crash-free rate is most useful when it guides action, so use it to drive fixing the high-impact crashes, the crashes dragging your rate down most are the ones to fix first. The rate tells you how you're doing; the high-impact crashes tell you what to fix to improve it.

Bugnet ranks crashes by affected players, so you know which to fix to raise your crash-free rate. So practice tracking your crash-free rate by tracking it from real player data, breaking it down per version and watching the trend, and using it to drive fixing the high-impact crashes, using the clearest stability metric to guide your stability work.

Track crash-free rate from real player data, break it down per version, watch the trend, and use it to drive fixing the high-impact crashes. Crash-free rate is the clearest single stability metric.
