Fix Broken iOS & Android Apps
Already have an app that crashes, stalls, will not build or keeps failing review? We start with evidence and reproduction, prioritize the failures users actually hit, implement bounded fixes and retest the affected paths.
Failure diagnosis
Which exact lifecycle or data transition makes the app crash or lose state?
App rescue for unstable releases, inherited codebases and defects that block customers or stores. We work against agreed platforms, repository access, constraints, milestones and acceptance tests—not a one-size-fits-all app package.
Reproduce with the affected build and device, follow the crash or ANR trace, then change the smallest responsible path.

Before/after reproduction, targeted regression tests, TestFlight validation when applicable, and release/rollback notes.
Document the observed results and remaining risks in the handoff.
Repair plan
Diagnosis and repair
Investigation and recovery
- Repository/build takeover: reproduce from a clean checkout and document missing dependencies, credentials and ownership.
- Crash symbolication and trace analysis using production diagnostics, breadcrumbs and representative repro steps.
- iOS Swift concurrency, memory, lifecycle, navigation, persistence and networking fault investigation.
- Android ANRs, Coroutines/Flow cancellation, process death, WorkManager, Gradle and device-specific defects.
- Authentication expiry, token refresh, deep-link loops, API compatibility and unreliable network recovery.
- Store-policy and release failures within app, metadata, permission or signing ownership boundaries.
- Minimal reversible patches with regression and negative-path tests instead of an unscoped full rewrite.
- Post-fix verification, staged rollout and a documented residual-risk list.
What your team receives
- Reproduction notes with affected versions, devices, logs and confidence level.
- A prioritized defect and root-cause report, separating confirmed causes from hypotheses.
- Patch set, focused automated tests and build artifacts where access allows.
- Release/retest checklist with rollback instructions and unresolved risks.

Frequently Asked Questions
Answers to your questions
Can you fix an app without rewriting it?
That is the preferred starting point. We identify the smallest safe change that resolves a confirmed fault. A rewrite is considered only when the existing foundation makes repairs disproportionately risky.
Can you recover an app without source code or signing access?
We can assess what is recoverable, but cannot promise a maintainable fix or store update without legitimate project, source and account access. A clean rebuild may be the only practical option.
Our Approach
How we work with your team
Discovery
We review your goals, existing environment and the systems or workflows involved.
Engagement planning
Code changes, integrations, production access and release support are agreed separately where needed. We define the delivery plan and responsibilities together.
Results and handoff
Your team receives the agreed implementation or findings, testing results and a clear next-step plan.
