Your app, working again.

I take over neglected or struggling apps, get them stable, and bring them up to date so your team can ship again. 15+ years building for iOS, Android, and the web.

Who I help

Founders, product leads, and operations teams who depend on an app they can no longer safely change.

Unstable apps

Crashes, slow screens, and one-star reviews that are costing you customers.

Store deadlines

Apple and Google raise their requirements every year. I get you compliant before updates are blocked.

Orphaned code

The agency or developer who built it is gone. I take over cleanly and document everything.

Legacy stacks

Objective-C, Java, or an aging web framework that slows every change your team makes.

Services

Fixed scope. Clear prices. No surprises.

START HERE

App Health Audit

A full review of your code, dependencies, build pipeline, crash data, store compliance, and security basics. You get a written report with a prioritized fix list and cost estimates.

From $2,500 · fixed · 1–2 weeks
FIX

Stabilization Sprint

Fix the top crashes, restore working builds, update SDKs and target versions, and get through store review.

Priced to fit your app · fixed quote after your audit · 2–6 weeks
MODERNIZE

Modernization Project

Objective-C to Swift and SwiftUI, Java to Kotlin and Compose, or an aging web stack to a current one. Delivered in phases, each with a fixed price.

Fixed price per phase · quoted from audit
MAINTAIN

Care Plan

Yearly OS and SDK updates, security patches, store compliance, crash monitoring, and hours for small changes, so it never falls behind again.

From $1,500 / month
How it works

From "nobody can touch it" to shipping again

01

Audit

I learn your codebase and tell you exactly what's wrong, what to fix first, and what it will cost.

02

Stabilize

Crashes down, builds green, store requirements met. Your app is safe to update again.

03

Modernize

Move to current languages and frameworks in phases, without stopping your releases.

04

Keep it current

A Care Plan handles every OS release and store deadline, so you're never stuck again.

What you're left with

Many rescue clients were burned by someone who kept all the knowledge in their head. I work the opposite way.

Clear documentation

Architecture, setup, and release steps any developer can follow.

A working build pipeline

Automated builds and releases you own, not tied to one person's laptop.

Accounts in your name

Repos, signing certificates, and store accounts organized and under your control.

Before-and-after numbers

Crash-free rate, build time, store rating, and release frequency, measured.

About

Hi, I'm Chantel.

I've spent more than 15 years building iOS, Android, and web apps. I've seen most of the ways apps break down, and I know how to bring them back without a risky rewrite. You work directly with me, from the first audit to the last release.

[One or two sentences about notable companies, products, or apps you've worked on.]

Questions

Do you work on apps you didn't build?

That's most of my work. The audit is how I get up to speed on someone else's code quickly and safely.

What if the code is a mess?

It usually is. I'll tell you honestly whether to fix, modernize in phases, or rebuild parts, and what each option costs.

Which technologies do you cover?

Swift, SwiftUI, and Objective-C on iOS; Kotlin, Compose, and Java on Android; React on the web; and React Native for cross-platform apps.

How much does it cost to fix an app?

It depends on what the audit finds. Most stabilization work starts around $15,000, and you get a fixed quote before any work begins, so there are no surprises. It is usually a fraction of what rebuilding the app from scratch would cost.

Will you sign an NDA?

Yes. All code and IP transfer to you on payment.
