Release Health

Release Health​

The Release Health section is designed to help teams monitor and compare the quality of two different app versions over customizable time windows. It enables data-driven decisions during rollouts and helps you catch regressions early by surfacing critical metrics related to app stability and user experience.

Whether you're preparing a new release, analyzing a canary rollout, or comparing production versions, Release Health gives you both high-level indicators and granular breakdowns of app issues.

What You Can Track​

Release Health currently supports insights into the following issue types:

  • Crashes
  • ANRs
  • Exceptions
  • Error Logs
  • Slow Spans

For each issue type, we provide:

  • Overall Impact Metrics:
    • % of affected users
    • % of affected session parts
  • Detailed Breakdown:
    • Impact per issue type
    • Comparison delta between selected versions

All metrics are computed as a comparison between two groups:

  • Group A (New Release) – the app version you're evaluating
  • Group B (Baseline) – the reference version you're comparing against

How to use​

Set Filters​

Select the app version and evaluation period for both Group A and Group B.
A preview panel will display:

  • Session Part Volume
  • App Adoption (within the selected time window)

These help you evaluate whether the comparison is statistically meaningful.

Once you're satisfied with your selection, click Apply to load the metrics.

💡 You can rename the group labels to something meaningful to your app or context.

Visualize Issue-Specific Metrics​

  • Affected Users per Issue – percentage of users impacted by a specific issue type (Crashes, ANRs, etc.), compared to Group B
  • Affected Session Parts per Issue – percentage of session parts impacted by a specific issue type, compared to Group B

Detailed Comparison​

A detailed table listing each individual issue (e.g., specific crash or exception), with impact metrics across both groups. This helps you:

  • Identify new or regressed issues in Group A
  • Quantify the impact of each issue type
  • Prioritize based on user/session impact delta between versions
