Ube Maintainer

App maintenance,
on autopilot.

Ube's agentic AI platform listens to your crash reports, user feedback, and dependency upgrades — then triages, reproduces, and opens verified pull requests (PRs). You ship features. It handles the rest.

THE PROBLEM

App maintenance is cumbersome.

Tests get skipped.

Engineers read the stacktrace or eyeball the migration doc. They ship "simple fixes" without proper . The bug survives the release and results in customer churn.

Unfixable bugs pile up.

Dependency issues, hardware specific edge cases, intermittent crashes — all require hours of debugging. And when the root cause is upstream, filing a proper bug report is rarely worth the effort.

Maintenance delays releases.

Internal testers find a missing null check moments before release. Engineering gets pulled back in. The exciting feature you actually shipped this sprint slips to next.

THE SOLUTION

Ube agent runs on your
repo around the clock.

Set up in 10 minutes. Automated from then on.

01Intake

Monitors all platforms.

Firebase Crashlytics, Sentry, Play Console , App Store reviews, support inboxes, dependency releases, all funneled into one timeline. Nothing slips through.

02Triage

Tracks bugs across binaries.

Stack traces are symbolized on intake, then deduplicated by signature across versions, OSes, and dependency upgrades. Per-issue state lives on a single dashboard — the source of truth your maintenance agent reads from.

03Fix

Reproduce, patch, verify, then open the .

Ube reproduces the bug on an emulator, writes the patch, and runs your test suite. Then it the app by hand, clicking through like a real user. Once the issue is verified fixed and nothing else broke, it opens a . Watch the GIFs, read the diff, merge.

“Hi Tara, thank you for the report. The crash you hit when opening saved recipes is fixed in v2.4.3, which rolled out to your device this morning. Please, let us know if you see it again.”

04Release

Close the loop with the customer who reported it.

Once the fix ships, Ube tracks which release it landed in, when it rolled out to production, and writes back to the original reporter. Angry one-star reviews turn into thank-yous, and your rating climbs week over week.

05Escalate

Reports bugs upstream when needed.

When facing an upstream bug, Ube opens a detailed issue on their repo — with repro steps, logs, and a minimal reproduction. When it can't reproduce or resolve a bug itself, it hands the thread back with everything it learned.

Outcomes

Less time maintaining.
More time building.

10-30%

of your team's engineering time reclaimed, based on early teams running Ube.

Reclaim engineering time.

Stop spending a third of every sprint debugging race conditions you didn't write. Hand the boring triage to Ube and continue shipping delightful features.

Your backlog stays lean.

Every incoming bug report is triaged, fixed, or followed up on, automatically. Nothing rots in the queue, so your task list stays short.

Catch bugs early.

Ube becomes your manual agent, clicks around the app like a human would. You no longer need to wait for a beta or alpha release to discover bugs.

Stay under Play's bad-behavior threshold.

Apps crashing on more than 1.09% of sessions or hitting above 0.47% get demoted in Play discoverability.

Higher app-store ratings.

Faster fixes plus a personal follow-up nudges users back into the review flow. Updated reviews compound into a better average rating for your app.

Keep tech debt in check.

Agentic coding ships features faster than ever, and quietly piles up bugs and shortcuts. Ube does the unglamorous cleanup in the background so velocity doesn't come to a halt.

FAQ

The details.

Ube always opens PRs, so you stay in control of what ships. Auto-merge is opt-in per repository, and even then it's gated behind your existing branch protections and required checks.

Your code runs in ephemeral, per-repo sandboxes that are destroyed after each job. We don't train on your code, and we don't keep it after the run. Self-hosting is offered for enterprise customers with strict privacy requirements.

React Native, Expo, Flutter, native iOS (Swift / Obj-C), native Android (Kotlin / Java), and Capacitor / Ionic out of the box. Other stacks can be onboarded on request. Get in touch.

Every pull request runs your tests plus a generated regression suite before opening, and the diff is yours to review. Marking a fix rejected teaches Ube to avoid that approach for the same signature, so it gets better at your codebase over time.
