App rescue

Stabilize, finish, or modernize a stuck product.

gammaLabz takes over codebases that are half-built, fragile in production, or blocked on upgrades. We start with a structured review — not a guess at fixed price — then propose a rescue sprint or ongoing engineering.

EU timezone · direct engineer access · paid discovery or defined build when the scope is clear

  • Confidential codebase reviews
  • Mobile and web stacks
  • Upgrade and stabilization work
  • Clear options after audit

Symptoms we see in rescue projects

  • The app crashes or behaves differently on production builds than in development
  • Dependencies are years behind and upgrades feel too risky to attempt
  • The previous agency or freelancer left without documentation or store access
  • Payments, auth, or push notifications work for one platform but not the other
  • Every new feature breaks something unrelated
  • Store review rejections or expiring certificates are blocking release
  • There is no automated testing and releases are manual and stressful
  • Backend and frontend were built by different teams and no longer align

Engagement options

How rescue work is structured

Codebase and architecture audit
Repo access, dependency review, release blockers, security basics, and a written summary of risks and recommended next steps.
Rescue sprint
Time-boxed work to fix the highest-severity issues — stability, store submission, critical bugs, or upgrade to a supported SDK.
Ongoing takeover
gammaLabz becomes your engineering team for continued development, releases, and infrastructure after the immediate fire is out.
Upgrade and modernization plan
Staged path for React Native, Expo, Next.js, or backend framework upgrades without a big-bang rewrite.
Testing and CI baseline
Minimum automated coverage and build pipelines so future releases are repeatable.
Handover documentation
Architecture notes, environment setup, and release runbooks so you are not dependent on tribal knowledge.

Is this the right fit?

Strong fit
  • You have an existing codebase and need an honest assessment before spending more
  • Production users depend on the product and downtime is costly
  • You can grant repo and environment access under NDA
  • You want engineers who will tell you if a rewrite is cheaper than continued rescue
  • Mobile, web, or backend rescue — we work across the stack
Probably not the right fit
  • You want a fixed-price full rebuild quote before anyone has read the code
  • There is no source code or it lives only on a former contractor's machine
  • You are not authorized to share the repository with an external team
  • You need a body-shop team to follow specs without questioning bad architecture

Rescue process

01
Confidential review
Access the repo, staging, and store accounts. Map architecture, dependencies, and what is actually blocking users today.
02
Written findings
Severity-ranked issues, recommended sequence, and engagement options — audit only, rescue sprint, or takeover.
03
Stabilize and unblock
Fix crashes, release blockers, and critical security or compliance gaps before new features.
04
Resume product delivery
Ship the backlog with testing and release discipline so the product does not stall again.
Pricing after audit
After a short call, we will tell you whether the project needs a paid discovery, a focused sprint or a full build. We do not quote a fixed rescue price before reviewing the codebase.

Client words

What teams say after shipping

“gammaLabz are responsive and I've never waited more than 24 hours for a reply. Fair pricing for what you get, and they've upgraded MyEsim GR enormously since I started working with them.”

Dimitris D.

Founder · MyEsim GR

“I started with nothing — no app, no store listing. About a month later the app was live on iPhone and Android, taking payments, and people were actually using it. I didn't think that was possible on my timeline.”

John R.

Founder · Guinea Pig Translator
