Ship mobile apps with confidence.
Sentinel runs automated UI and unit tests across signup, checkout, paywall, notifications, and analytics events. It catches layout breaks on real device sizes, surfaces crashes before release, and suggests fixes your team can apply in one click.

Runs with your frameworks and CI
Catch mobile bugs before your users do
Automated tests across signup, checkout, paywall, push notifications, and analytics event validation.
Device profiles that catch layout breaks on small screens, notches, and tablets before App Store review.
AI-generated fixes for failing UI tests and unit tests, ready for your team to review and merge.
Mobile UI testing
Pixel-level checks on real device sizes. Sentinel flags clipped buttons, overlapping text, and broken safe areas.
Crash detection
Simulates edge cases and memory pressure to surface crashes, null pointer exceptions, and race conditions early.
UI + unit test generation
Sentinel writes XCTest, Espresso, and Detox specs from your flows, then keeps them updated as screens change.
Layout breaks caught before App Store review
Sentinel renders your flows on real device profiles, from the small iPhone SE to notched Pros and tablets, and flags clipped CTAs, overlapping text, and broken safe areas pixel by pixel.
- Device matrix across iOS and Android form factors.
- Safe-area and notch checks on every screen.
- Visual diffs so regressions never slip through.
Built for teams shipping mobile fast
Mobile engineers
Generate and maintain UI and unit tests automatically, so coverage keeps up with how fast screens change.
QA teams
Replace brittle manual passes with a runner that checks every flow on every device, on every build.
Founders & PMs
Ship updates without the dread, knowing crashes and layout breaks are caught before they hit the stores.
Sentinel caught a checkout crash on Android 14 the day before release. That one fix probably saved us a one-star review pile-up.
Questions about Sentinel
Sentinel runs automated UI and unit tests across your core mobile flows, signup, checkout, paywall, notifications, and analytics events, and checks layout on real device sizes while catching crashes.
Sentinel generates and runs XCTest for iOS, Espresso for Android, and Detox for React Native, and plugs into CI systems like GitHub Actions, Bitrise, and Xcode Cloud.
When a test fails, Sentinel highlights the issue on a device preview and proposes a concrete code fix, for example adjusting safe-area insets or guarding an offline code path, ready for your team to review and merge.
Yes. Sentinel runs on every build in your CI pipeline and reports pass/fail status, layout issues, and crashes before release, so regressions are caught before users see them.
A typical Sentinel engagement is 3 to 5 weeks, including CI integration and a device matrix tuned to your audience.
