TriVisionTech
About
TriVisionTech is an independent software studio based in Brazil. We design, build and publish our own applications - native Android apps on Google Play and free web tools that run in any browser. Everything on this site is something we made and maintain ourselves.

Our approach
We build small, focused products and keep improving them. Each app is meant to do one job well rather than try to do everything. We favour clean, uncluttered interfaces, offline-first behaviour wherever it makes sense, and privacy by default - most of our apps need no account and keep your data on your device. Releases go out on Google Play and are updated continuously based on how people actually use them.
How we build
- Modern Android. Kotlin and Jetpack Compose, built with lifecycle correctness, state management and performance in mind.
- Offline-first. Features keep working without a connection whenever the task allows it.
- Privacy by design. No unnecessary permissions, no third-party tracking inside the apps, data kept on the device unless you choose to export it.
- Accessibility and testing are part of the build, not an afterthought.
What we make
Our Android catalogue spans productivity (PDF Scan, PDF Reader Pro), personal finance (Grana Guru), everyday utilities (MetaCalc, Authra), media (Audiva Music, FotoGrid Pro) and lifestyle (WorldCoffee). Alongside them we publish a growing set of free, browser-based tools - unit and colour converters, calculators, text and image utilities - that run entirely on your device with nothing uploaded to a server.
