Zero tracking by design
We add no analytics, ad SDKs or fingerprinting.
Android‑only studio
Not cloud‑linked, but fully on‑device
We build offline‑first Android apps with Kotlin and Jetpack Compose. No trackers, no advertising ID, no hidden code after install.
- Pure Android
- Offline first

Glasshouse Rounds
Glasshouse Rounds
Built like everything else we make: native, fast to open, quiet about your data.
- Functions offline
- Stores data locally on your device
- Requests only needed permissions
- No accounts, no ads, no analytics SDKs
Our offerings
From sketch to release, we handle every Android detail correctly.
Native Android apps
Kotlin from day one. Apps that run smoothly on modest hardware.
Compose UI
Declarative screens with Material 3, adaptive layouts and fluid motion.
Local‑first data
Room and DataStore store everything on the device, even in a tunnel.
Battery & performance
We profile start‑up, jank and background work, then monitor Android Vitals.
Accessibility
TalkBack labels, high contrast and large‑text support are built in.
Long‑term care
Signed builds, staged Play rollouts and regular updates as Android evolves.
Our workflow
Four stages from first call to ongoing support. Each yields a reviewable artifact.
Discovery
Define the problem, users and the behaviours we must avoid.
Architecture
Sketch screens, data flow and permissions before any production code.
Build
Write Kotlin, Compose and tests, deliver small builds for trial.
Release & care
Stage rollout on Play, then monitor, fix and update for new Android releases.
One-way data flow: the interface observes state, and the repository owns the data.
