One flat monthly fee keeps your app compliant, secure, and in the stores. No full-time hire.
The senior team behind drtalk, a 2024 Good Design Award winner we have run for six years, and STARTTS for NSW Health. The same team delivered the NGM Group banking app: 4.7 stars across 325,000+ customers.
After a platform deadline you can't ship updates or security fixes. We keep you ahead of it. See the August 2026 deadline →

Carrying a developer just for the occasional release? Tell us about your app and we will run a free App Health Check, then set one flat monthly price to keep it compliant, secure and in the stores.
Agency built it, then moved on?
We adopt apps mid-life and keep them shipping. No rewrite: we pick up your React Native, Flutter, Xamarin or native app and take it from here.
The usual path is a build project, then a thin support agreement that nobody really owns. Updates slip, store deadlines creep up, and one day a customer tells you the app is broken. App Care flips that: a flat monthly service that keeps your app compliant, secure and in the stores, run by the same senior team, so you never have to think about it. It is common overseas and rare here. That is the gap we fill.
Is this just a support contract?
No. A support contract is reactive and owned by no one, so the work that keeps an app alive quietly stops. App Care is a managed service: the same senior team keeps your app compliant, secure and in the stores for a flat monthly fee, and stays ahead of store and OS deadlines for you.
Donnish is a small, senior team based in Brisbane with a blended delivery team in Aussie hours, not a marketplace and not a single contractor. Founder Quinn van Heerden has over 20 years leading software delivery and is in the detail on every engagement.
We do not just build apps, we keep them alive. The people behind Donnish have run drtalk in production for over six years and support the STARTTS platform for NSW Health, and have delivered apps for institutions including NGM Group and MUFG across banking and financial services. That is over 20 years of delivery behind the team, across every stack including the Xamarin apps most teams will not touch.
CAMLAP, the Flutter platform we built and now run for STARTTS, part of NSW Health. It delivers trauma-informed clinical assessments in a survivor's first language across 179 nationalities, with a no-code builder so clinicians create their own questionnaires. We keep it compliant, supported and improving on a managed retainer (Silver plus) as the program expands from NSW toward a national rollout.
Read the case study →drtalk, the dental collaboration platform we have built and run for over six years, serving thousands of US practitioners across web, tablet and mobile. It is a modular .NET platform on Azure with clinical channels, referrals and Stripe-powered payments and payouts; we migrated its app from Xamarin to React Native, work that won a 2024 Australian Good Design Award. We run, secure and evolve the whole platform end to end, a Platinum plus engagement.
Read the case study →Deep on the stacks nobody else will touch: the team behind Donnish has shipped Xamarin apps for WikiCamps (migrated to Flutter), Victoria DEECA (two government apps), MUFG (Miraqle and Member Centre) and an Australian crypto exchange.

Your app is only as dependable as the cloud behind it. We run both: the mobile platforms you ship on, and the certified Azure and Google Cloud backends that keep them up.
Held by our team, not contracted out: Microsoft Azure and Google Cloud, across development, data and infrastructure.
Running an app you depend on should be quiet and predictable. Here is how the service is shaped around that.
You buy an outcome, not a tier. Every tier covers app hygiene; Gold and Platinum add the work beyond the binary.
Your matchWe'd start with a sprint, then Gold.
The free App Health Check confirms the plan and a single flat monthly price.
Everything in. One flat monthly fee, set per app at the free check.
Maintained
One app kept compliant, secure and stable.
Managed and improving
An actively used app that must keep improving.
Run in full
Ongoing development, not just maintenance: a semi-permanent team running it end to end, backend and cloud included. Often government or large.
This is what your free App Health Check delivers: store and compliance, security, performance, code health, engagement, prioritised findings and a 30-day roll-forward plan.

Keeping the binary compliant, secure and broadly up to date: store, OS and SDK compliance roll-forward on iOS and Android; dependency and security patching; third-party library risk review; crash and performance monitoring with alerts; release management to the App Store and Google Play; minor app changes; and a monitoring and analytics baseline.
Yes, in every tier. Bounded and forecastable, which is why it can be a fixed monthly price.
The wider platform we can run, proven on drtalk: backend and API maintenance on Azure, cloud and infrastructure management, integrations across payments, identity, messaging and video, feature development beyond minor changes, technology migrations, design modernisation and analytics deep-dives.
Scoped once we have context. Light in Gold, full in Platinum, or as fixed-price add-on projects. Priced after the App Health Check, not guessed up front.
The binary, its direct dependencies and its store presence are hygiene: predictable, repeatable, and the same shape on every app, so they sit in every tier at a fixed price. The backend, cloud, integrations and features are the expand layer; their effort depends entirely on the app, so we price them once the App Health Check has given us context.
This protects the no-surprises promise on the core, and gives us an honest, evidenced reason to do more once we have earned the context.
The SLA rows above mean specific things, and Silver is deliberately best-effort on resolution so nobody expects a guaranteed P1 fix from an email. These are starting definitions, pending the full SLA schedule.
A Silver client who emails a P1 gets a same or next business day response and best-effort restoration, but no committed restoration or resolution time. Clients who need a committed P1 restoration belong on Gold (8 business hours) or Platinum (4 business hours, with incident management and rollback).
These are starting definitions for the MSA, not the final schedule. The full matrix of P2 to P4 targets, exclusions and dependency carve-outs is being built out.
Effort is heaviest up front, then settles into maintenance. The numbers below are indicative and vary per app, but they help you see where the work goes. All support is delivered 8am to 6pm AEST on Australian working days, not 24/7.
| Period | Silver | Gold | What is happening |
|---|---|---|---|
| Months 1 to 3 | ~10 to 15 hrs/mo | ~20 to 35 hrs/mo | Setup, stabilisation, first updates or feature. The heavy part, smoothed across the year. |
| Months 4 to 6 | ~6 hrs/mo | ~10 to 12 hrs/mo | Settling in: compliance, minor updates, monitoring. |
| Months 7 to 9 | ~4 hrs/mo | ~6 to 8 hrs/mo | Steady maintenance. |
| Months 10 to 12 | ~4 hrs/mo | ~6 hrs/mo | Maintenance, with a spike around the annual iOS and Android deadlines. |
The included monthly change pool (Silver up to 8, Gold up to 12) covers the steady months. The heavier first quarter is the onboarding and stabilisation work, quoted and smoothed so you still pay a flat monthly amount. Platinum is sized at the assessment.
The flat monthly covers the standard setup, ongoing app hygiene for the tier, the change pool, monitoring, analytics, releases and support. The standard setup is our onboarding plus an initial, time-boxed pass at the app: if the assessment raises urgent issues, we do as many as the time-box allows, or build a small feature you want.
For a flat fee to work, a few things are assumed and stated up front, in the proposal and the MSA:
These assumptions are what keep the price flat and the relationship clear.
These mirror the terms Donnish already runs with STARTTS, part of NSW Health, so they are proven, not theoretical.
Taking on an app we did not build is real work, so we quote it up front and let you smooth it. The free App Health Check scopes it precisely: the hours, and what is needed. We then quote a fixed, capped onboarding and stabilisation figure, and you choose to pay it once or smoothed across the first six to twelve months as a temporary uplift that then steps down to the standard monthly fee.
Apps we already built need little or no onboarding, so existing and warm clients stay an easy yes. Because we do not know an app's condition up front, the assessment sizes the onboarding for that specific app and sets the all-in price before you sign. The unknown is priced in at the start, never billed as a surprise a month later.
Beyond the retainer, larger pieces are scoped and fixed-price-quoted. Indicative starting figures, sized per app at scope.
Indicative only, to be confirmed at scope. Migrations vary widely with app size and stack, so treat $15,000 as a floor for a small app, not a typical figure.
This value point only works because we run our own AI-assisted tooling across the whole service: automated dependency and security scanning, monitoring, analytics, release pipelines, and AI through the delivery workflow. Using our standard tooling throughout is mandatory, not optional. It is how we keep the service efficient and the price fair, and how a small team runs many apps well.
Your data stays yours. Donnish will protect it as far as is within our control. The precise wording sits in the MSA.
