Android app development in London and the UK

Polyforge Studios is a UK mobile software studio shipping production Android apps—with emphasis on Kotlin, Play policy alignment, and engineering that survives real devices and OS updates.

Whether you are a founder with a first Play Store release or a team extending an existing product, Android work is never “just Java/Kotlin screens.” It is permissions, background limits, notification channels, OEM battery rules, and review policies that change every year. Our engineering notes on Android 14+ reflect how we actually build—not slide decks.

What we ship on Android

• Native Kotlin modules where the platform contract matters—alarms, foreground services, deep integrations.
• Cross-platform surfaces with Expo when velocity and shared UI win, combined with native pieces where needed (how we split the stack).
• Store-ready builds: signing, release tracks, privacy declarations, and crash/analytics hygiene.

Why location still matters for UK clients

We are headquartered in London (Covent Garden). Time zone overlap, clear English contracts, and GDPR-aware defaults matter for regulated and consumer apps alike. We work with distributed teams globally, but our legal and operational home is the United Kingdom.

Example product: WakeQuest

Our flagship habit app pushes Android scheduling and UX to the limit. If you need similar reliability—without cutting corners on compliance—see WakeQuest and imagine that discipline applied to your roadmap.
