How we build

Independent by design. Private by default.

One compact studio, five focused products, and a clear standard for what software should ask of you.

Private by default

Core app data stays on your device. Accounts and sync servers are not required for your documents, budgets or creations.

Offline-first

Aeroplane mode is not an edge case. Core scanning, budgeting and GIF workflows — and both games — remain available with zero connectivity.

Light on your phone

Fast launches, small installs and interfaces that follow modern platform design instead of fighting it.

Spoken in your language

Our apps ship localised into dozens of languages, from Afrikaans to isiZulu, because good tools shouldn't need translation.
