Launch is the beginning, not the finish line
Ongoing maintenance and support for apps and web products — ours or anyone else’s — from bug fixes and OS updates to new features, on a plan built around how much support you actually need.
Why a support retainer
Most bugs and outages happen after launch, once the team that built the product has moved on to the next one. A retainer means someone who already knows your codebase is watching it.
One Team, No Ramp-Up
We stay familiar with your codebase between requests, so every fix starts with context instead of a fresh audit.
Fixed Monthly Cost
A predictable monthly retainer instead of an hourly invoice that spikes right when something breaks.
Critical Issues, Fixed Fast
Whatever your plan, a critical issue — an outage, data at risk, a security exposure — gets fixed within 24 hours, not just acknowledged.
Works With What You Have
We support products we didn’t build too — there is no requirement to have shipped with Applefy first.
Covered Long After Delivery
Stay on any plan long enough, and the fixes and features we ship from then on are guaranteed for life — in as little as 2 months on Priority.
Senior Engineers, AI-Accelerated
Every fix and update is handled by senior engineers, not junior staff or an automated pipeline — AI tooling speeds up triage and routine work, but a person who knows your codebase makes every real decision.

Stay with us, and it’s covered for life
Complete 6 consecutive months on any plan — or just 2 consecutive months on Priority — and every fix or feature we deliver from then on is guaranteed for life. If it breaks because of a defect in what we shipped, we fix it free, whenever that happens.
How it works
- 01
Scope
We review what you have, agree on the plan that fits, and set up access to your codebase and infrastructure.
- 02
Support
Bugs get fixed, updates get applied, and small improvements get worked through in priority order — tracked and reported.
- 03
Improve
As trust builds, support expands into small features and proactive work instead of only reacting to what breaks.
Common questions about App Maintenance & Support
Yes. We onboard into an existing codebase the same way we would our own — a short review up front to understand the architecture, then support starts on your plan’s timeline.
Any defect in a change we delivered, fixed for as long as you need it — once you’ve completed 6 consecutive months on any plan, or just 2 consecutive months on Priority. It does not cover breakage caused by a new OS release, a third-party API or SDK change, or edits made outside Applefy after we delivered the work.
A small improvement is a tweak to something that already exists — a copy change, a UI adjustment, a minor workflow fix. A new feature, a redesign, or anything that needs its own scoping and design work is a project, not maintenance, and we’ll quote it separately rather than squeeze it into the plan.
Yes, month to month. Most clients start on Care or Growth and move up as the product grows.
That’s fine — plans are month to month with no minimum term. The Lifetime Fix Guarantee simply starts once you reach 6 consecutive months (2 on Priority).
The per-plan response time (2 business days on Care, 24 hours on Growth, same-day on Priority) is for routine requests. A genuine critical issue — an outage, data at risk, a security exposure — gets fixed within 24 hours regardless of plan; it never waits behind the routine queue.
Not exactly, though Priority includes Fractional CTO-level guidance as part of the plan — architecture direction, hiring input, and technical decisions, alongside the hands-on maintenance work. On Care and Growth, Fractional CTO remains a separate, complementary engagement rather than something bundled in.
Not directly — this plan keeps what you have running and polished, it isn’t a channel for new feature development. Bring us the idea and we’ll scope it as its own project, so it gets the design and planning a real feature needs instead of being squeezed in alongside bug fixes.
