iOS OS-Compatibility Updates
Swift and Xcode upgrades, deprecated API migrations, and TestFlight validation — so your app survives every iOS release without breaking in production.

App Maintenance and Support Services for Production Apps
Apps break silently — an OS update, an expired certificate, an untracked crash spike. We monitor, patch, and update iOS, Flutter, and React Native apps so yours doesn't — with same-week response on critical issues.

WHY
CHOOSE
US
Built for continuity, not another rebuild pitch
We don't rebuild what isn't broken
We fix what's failing — crashes, CVEs, store rejections — without pitching a ground-up rewrite you didn't ask for.
Patch-first philosophy
Same developer, every ticket
Your maintenance engineer owns the codebase history. No rotating support queue re-learning your app each sprint.
Named engineer on every engagement
30-day replacement guarantee
If your dedicated maintainer isn't the right fit, we swap them within 30 days — no billing gap during transition.
Zero downtime developer swap
Stack-matched specialists only
iOS, Flutter, and React Native maintainers — not generalists learning your framework on your production codebase.
Role matched to your stack
Audit before we touch code
Every engagement starts with a health audit — crash logs, dependency versions, store status — before the first patch.
Free health audit included
Monthly retainer, not hourly surprises
Fixed monthly pricing scoped to your tier. No nickel-and-dime hourly billing on routine patch and monitoring work.
Predictable monthly spend

Questions
Cost depends on your app's platform, size, and how deep you need us involved — from monitoring-only coverage to a dedicated enterprise retainer. We also offer one-time health audits and emergency hotfixes if you don't want a retainer. Every quote is scoped after a free health audit, so you're never paying for coverage you don't need.
Yes — OS updates, SDK deprecations, and dependency vulnerabilities pile up after launch whether you're watching or not. We recommend at least monitoring-level coverage; apps we've taken over without prior maintenance usually show rising crash rates and store-compliance risk within 6–12 months.
When you work with TechReforms, your plan includes crash and performance monitoring, OS/SDK compatibility updates, security patching, dependency audits, and App Store/Play Store resubmission handling. On higher tiers, we also add dedicated developer hours for bug fixes and small feature changes.
At minimum, quarterly — to stay ahead of iOS/Android OS releases and SDK deprecations. We schedule your upgrade passes ahead of Apple and Google's annual compatibility deadlines so you're never scrambling to avoid a forced rejection.
Yes. We start with a health audit — reviewing your crash logs, dependency versions, and code structure — before we assign a developer, regardless of who built the original app or how messy the codebase is.
It depends on your plan: 72 hours on Starter, 48 hours on Standard, 24 hours on Growth, and same-day on Enterprise retainers. If you're not on a retainer, we still take on emergency hotfixes within 24 hours.
Yes — we handle your metadata updates, screenshot refreshes, and policy-compliance changes for App Store and Google Play resubmissions as part of every Standard plan and above. TechReforms treats this as routine maintenance, not a separate project.
You do, always. We write IP ownership into every contract, and we sign an NDA before we touch your repository or store access — that's non-negotiable at TechReforms, not an upsell.
