About

Focused apps.
Trusted by users.

Zavi Studio is an independent Android development studio focused on building lightweight, privacy-first utility apps for everyday use.

We believe apps should do one thing well — without dark patterns, unnecessary permissions, or hidden data collection. Every product we ship is designed to be fast, focused, and genuinely useful.

Our entire catalog is built with Kotlin and Jetpack Compose, following Clean Architecture principles. We take quality seriously — from architecture to Play Store listing.
