Your app breaks with every OS update
Apple and Google ship major OS versions every year and smaller ones constantly. An unmaintained app eventually breaks, gets warnings, or is pulled. We keep yours ready before each release lands.

The cost of neglect
Is your app slowly falling apart?
Apps are not set-and-forget. If any of these sound familiar, your app needs proactive care before it costs you users or its place in the store.
You find out about crashes from reviews
If one-star reviews are how you learn the app is crashing, you are losing users daily. Proper crash monitoring alerts you to problems before they spread.
Security vulnerabilities going unpatched
App dependencies and SDKs get security advisories all the time. Unpatched apps put user data at risk. We monitor and patch so your app stays secure.
The store threatens to remove your app
Apple and Google enforce minimum SDK targets and policy changes, and delist apps that fall behind. We keep your app compliant so it stays published.
Small changes take weeks or never happen
When the original developer has moved on, even a text or price change becomes a project. A maintenance plan gives you a reliable team and a fast turnaround.
The app has slowly gotten slower
Performance degrades over time as data grows and dependencies age. Without ongoing care, launch time and responsiveness slip and users notice. We keep it fast.

Trusted to keep apps healthy
Our app used to break every September with the new iOS. Since moving to their maintenance plan, every OS update has been a non-event because they test the betas ahead of time. Our crash rate has never been lower.
They monitor our crashes and usually have a fix deployed before we even notice. The monthly report tells us exactly what is happening with the app in plain language. It is the most reliable vendor relationship we have.
We inherited an app from a team that disappeared. They audited it, patched the security holes, brought it up to current SDK targets so Google stopped warning us, and now keep it healthy. They saved the product.

App maintenance FAQs
How much does app maintenance cost?
App maintenance plans typically run from $400 to $3,000 per month depending on the app complexity, platforms, monitoring needs and included hours. We offer a free audit of your app to recommend the right plan before you commit.
What does an app maintenance plan include?
OS-update readiness, crash monitoring and fixes, security and dependency patching, store-compliance updates, performance monitoring, a monthly report, a bucket of hours for fixes and improvements, and priority support. Exact inclusions vary by plan.
Can you maintain an app you did not build?
Yes. Most of our maintenance clients are on apps we did not originally build. We start with an audit to understand the codebase, document its state and patch anything urgent, then take over ongoing care.
Why do apps need maintenance?
Mobile apps are not set-and-forget. Apple and Google release OS updates and change policies and SDK requirements constantly, dependencies get security advisories, devices change, and performance degrades as data grows. Without maintenance, apps break, get delisted or become insecure.
How quickly do you respond to issues?
Critical issues like crashes or a store delisting are addressed within hours. Standard issues are handled within one business day. Our hours overlap with US, UK and Canada time zones, so most fixes land overnight your time.
Do you handle both iOS and Android?
Yes. We maintain native iOS and Android apps and cross-platform React Native and Flutter apps, keeping both platforms current, compliant and stable.
What happens when a new iOS or Android version releases?
We test your app against the public betas ahead of the release, fix anything that breaks and update for new requirements, so when the OS ships your app already works. No scramble, no broken release day.
Can you add new features, not just fix bugs?
Yes. Maintenance plans include improvement hours, and we scope larger features separately. We treat your app as a product that should keep getting better, not just stay alive.
Do you maintain the backend too?
Yes. Most apps depend on a backend and APIs. We keep the server, APIs, dependencies and infrastructure updated, monitored and reliable alongside the app itself.
What is in the monthly report?
Crash-free rate and trends, performance metrics, updates and patches applied, store status, work completed from your hours, and recommendations. Written in plain language so it takes minutes to read.
Can I cancel the maintenance plan?
Plans are monthly rolling with 30 days notice. We do not lock you into long contracts. If you move on, we provide a full handover of the codebase, accounts and documentation.
Do I still own my app and accounts?
Yes. You own your app, your code, your App Store and Play accounts and all your data. We access them to maintain the app, not to control it, and you can move at any time.
Ready to stop worrying about your app?
Tell us about your app and where it hurts. We will audit it and recommend the right maintenance plan, usually within one business day.
