Kotlin and Compose, across a real device spread
Modern Android engineering that accounts for the devices your users actually own, not the flagship on the designer's desk.

- Jetpack Compose
- Room

Android App Development
Android quality is mostly a testing question. We run on a device matrix that includes mid-range hardware and older API levels, because that is where the crashes and the jank live.
Jetpack Compose is the default, with Material 3 theming that respects dynamic colour without letting the brand disappear.

What is actually included
Scope is agreed line by line in the framing week. This is the menu it gets drawn from.
- Jetpack Compose and Material 3
- Kotlin coroutines and Flow architecture
- Room, WorkManager and background sync
- Play Billing integration
- Wear OS and large-screen adaptation
- Device matrix and instrumentation testing
- Play Console release tracks
- Performance and battery profiling
Typical stack
Four steps, and you can stop after any of them
Every stage produces something you own outright. Nothing is held hostage to the next invoice.
- 01
Framing week
A paid week where we map the constraints, the existing systems and what success has to look like in numbers. You keep the output whether or not we continue.
- 02
Architecture & plan
A written technical plan with the trade-offs made explicit, a milestone schedule, and a fixed budget band for the first release.
- 03
Build in the open
Two-week increments, a preview URL from day three, and a Slack channel where your team can see the work rather than wait for a demo.
- 04
Launch & operate
Load testing, runbooks and monitoring before go-live, then a support window while your team takes the wheel — or a retainer if you would rather we kept it.
Usually paired with
Projects rarely stay inside one service line. These are the ones that most often come along with it.

Android App Development: the questions we get asked
If yours is not covered, ask it directly — the reply comes from whoever would lead the work.
With a paid framing week. Two of our people read the existing code, talk to whoever operates the system daily, and produce a written technical plan covering approach, trade-offs, milestones and a budget band. You keep that plan regardless of what happens next.
The people you meet in the framing week. Clownmind runs senior-only delivery teams of three to five, and we do not hand projects to a second bench after the pitch. Kotlin, Jetpack Compose, Room and the rest of the stack listed above are things our team uses daily, not things we subcontract.
Most first releases land between eight and sixteen weeks depending on integration surface. We ship in two-week increments with a preview environment from day three, so there is something real to look at long before launch.
Load testing, runbooks and monitoring go in before go-live. After that you either take it in-house with a documented handover — which is what we design for — or keep us on a retainer for operations and continued delivery.
Yes, from the first commit. Work happens in your repository, under your organisation, on your cloud accounts. There is no proprietary Clownmind framework you have to keep paying to license.
