01
Diagnose the risk
Review the current app, codebase, release process, store presence, crash data, user complaints, and business pressure before prescribing work.
Mobile app maintenance & rescue
Get your existing mobile app back on track.
RapidLabs helps SaaS teams, founders, and agencies take over, stabilize, and improve iOS and Flutter apps — fixing crashes, cleaning up technical debt, restoring release momentum, and supporting ongoing app store delivery.
Senior mobile execution for production apps across native iOS, Flutter, Firebase/Supabase, backend systems, payments, and app store support.
Choose what you need
Different mobile app problems need different entry points.
Use the page that matches your situation: ongoing maintenance, codebase takeover, urgent stabilization, or agency mobile delivery support.
Maintenance
Maintain an existing mobile app
For live iOS or Flutter apps that need reliable releases, bug fixes, SDK updates, app store support, monitoring, and ongoing improvements.
View offerTakeover
Take over a neglected codebase
For apps left behind by a previous developer or agency, with unclear build setup, release risk, technical debt, or missing handover context.
View offerStabilization
Stabilize crashes and release blockers
For unstable apps that need fast progress on crashes, performance issues, app store rejection, dependency problems, or risky releases.
View offerAgency partner
Add mobile capability to your agency
For web, design, AI, no-code, and product agencies that need trusted iOS/Flutter execution behind the scenes.
View offerApproach
Maintenance work starts with clarity, not a bigger scope.
RapidLabs uses a simple recovery loop: diagnose, prioritize, stabilize, and maintain. Each step creates an artifact or release that moves the app forward.
02
Prioritize the recovery plan
Separate urgent blockers from nice-to-have improvements. The client gets a clear sequence for stability, launch, and maintainability.
03
Stabilize and ship
Fix the issues that matter most: crashes, broken flows, store rejections, slow releases, fragile dependencies, and missing monitoring.
04
Maintain momentum
Turn the audit or sprint into a repeatable release rhythm with monitoring, small improvements, app store support, and senior mobile judgment on call.
Proof
Senior mobile judgment, not anonymous agency staffing.

FAQ
Useful answers before a first email.
Existing iOS, Flutter, and app-backed products that need ongoing support, reliable releases, crash fixes, app store help, technical debt cleanup, or takeover after a previous freelancer or agency.
No. Rescue and stabilization are the sharpest entry points, but RapidLabs can also build focused new mobile products, SaaS companion apps, backend systems, Firebase/Supabase integrations, payments, and AI-assisted features.
Send the app link, current issue, technology stack, and what business outcome is at risk. If the fit is good, RapidLabs proposes a fixed-scope audit with a short timeline and clear deliverables.
Yes. Takeover work can include codebase review, dependency cleanup, release-process review, crash monitoring, app store support, documentation, and a prioritized recovery roadmap.
Yes. Launch and stabilization support can include store submission preparation, rejection fixes, metadata review, build signing, release checklists, and post-release monitoring.
RapidLabs works with native iOS, Swift, Flutter, Firebase, Supabase, TypeScript, Node.js, REST APIs, WebSockets, Stripe, PayPal, Apple Pay, analytics, crash monitoring, and AI integrations where they make sense.
