About Arcadia Lab

Arcadia Lab is an independent studio focused on what Android users in Latin America need. We start with everyday situations in the region and build apps around them.

Everyday life in the region

LED Banner is made for moments like cheering at the stadium and celebrating carnival. Paredão Play takes its cue from Brazil’s paredão sound systems.

Lightweight and offline

The core features work with the files and tools already on your phone.

Clear permission requests

Each app explains why it needs access and how it uses data.

Updates shaped by feedback

We release updates and use suggestions and bug reports to guide improvements.
