For mobile app owners, not end users
Your iOS app is broken. Here is how we fix it.
Time is money. If you own an iOS app that is crashing, losing users, or bleeding store ratings, this page is for you. We audit first, diagnose the actual root cause, then fix on a flat fee. Senior Swift, SwiftUI, and React Native hands. The longest turnaround we've shipped took a healthcare app from 0.7 stars to 4.4 stars over 18 months of focused work.

Rescue outcome
0.7★ → 4.4★ over 18 months
5× customer growth (100 → 500+) after we took over a failing React Native healthcare app on iOS, weeks before the anchor client would have walked. Cold start cut from 3 seconds to under 0.5. Crashes reduced from 500-1,000 per release down to 50-100. Biweekly crash triage still running on the team that took over. Per-engagement numbers from a recent rescue.

These are the situations we see most often when iOS apps come in for rescue.
Crash-free rate under 95% on real devices
Crashlytics, Sentry, or App Store Connect crash reports show a crash-free session rate below 95%. Specific device models, OS versions, or screen sizes account for most of the failures. Your team has tried to fix it. It keeps coming back.
App Store rating trending down or stuck below 4 stars
One-star reviews are accumulating faster than five-star reviews. The recent average is dragging the all-time average down. Each rejected reviewer reply makes it worse. The review thread is becoming a liability.
Cold start takes more than 3 seconds to first screen
Users open the app and stare at the launch screen. Some never make it past first paint. Cold start performance is dragging down your retention. The startup path is doing too much work.
Push notifications, in-app purchases, or Sign in with Apple are broken
Critical Apple platform features have drifted or never worked correctly. Push tokens dropping. IAP transactions silently failing. Sign in with Apple returning incomplete user records. The platform integration code has decayed.
iOS SDK target falling behind or App Store compatibility warnings
Xcode versions, Swift versions, and minimum iOS targets all march forward. Your project is pinned to old versions because every upgrade attempt broke something. App Store Connect is now flagging build target warnings on submission.
Wearable companion (Apple Watch) features failing in production
watchOS app shipped without the paired-phone handshake working. Complications not refreshing. HealthKit permissions throwing errors after iOS updates. The companion is degrading the brand instead of strengthening it.
How an iOS rescue actually runs
Four stages. Clear, concrete steps. Every step has a deliverable you can point to.
Paid Technical Audit
Mandatory first step. Read-only repo access. Standalone product. You walk away with a written report whether or not you move forward with the rescue.
We read the codebase, the crash reports, the App Store Connect analytics, and the review history. We test on real devices across OS versions and screen sizes. The audit produces a severity-ranked findings list, a crash-cause root analysis, and a rescue plan. Five working days, fixed-fee. This is non-negotiable: rescue quotes without an audit are guesses.
Fix plan
We turn the audit's findings into a flat-fee rescue scope. You see the exact fix list and the dollar number before any rescue work starts.
Some fixes are surface-level (specific crash dialogs, specific OS-version handling, specific Apple platform integration bugs). Some require architectural work (the startup path is too heavy; the data layer needs reorganization). The audit tells you which case you are in. If a rebuild is the right answer, we say so and re-scope as a Build, not a stretched rescue.
Executed fixes
Hands-on takeover. Read/write repo access, daily TestFlight builds, weekly sync. We ship in the order the audit prioritized.
Stop the bleeding first: highest-volume crashes, App Store rejection blockers, the issues bleeding ratings. Then cold start, then platform integration fixes, then wearable companion stabilization. Daily TestFlight builds to your team. We do not add feature work during the stabilization phase. Ratings improve as the apologies stop and the fixes ship.
Handoff and stability window
Handoff docs to your team, plus a 30-day stability window. Then you pick your next path.
Your team takes the wheel with the handoff package: runbooks for the release pipeline, crash-triage process, App Store Connect submission flow, and the architectural decision records explaining every non-obvious choice in the fixes. A 30-day stability window follows handoff: we respond to anything the rescue surfaced in production.

How much does an iOS rescue cost?
Audit-first, quoted fast. Flat-fee rescue scope from the audit's findings. No estimates, no stretched engagements.
iOS App Rescue
Starting at $8,000 · audit first, then quoted
Audit-first ($2,500 Quick Scan or $5,000 Full Audit). Flat-fee rescue scoped from the audit's findings. Deposit + milestones. 30-day stability window after handoff.
Scope is locked after the audit. If the findings show the right answer is an architectural rebuild, we re-scope as a Build, not a stretched rescue.
