Why Trei

Trei is a one-person studio, on purpose. Every app here is built, shipped, and supported by the same hands — fewer apps, slower launches, and more care per pixel.

  • Privacy, not theatre

    No third-party trackers, no ad networks, no data resale. The analytics we keep are the ones that help us fix bugs.

  • Calm by design

    No streaks to protect, no red badges, no manufactured urgency. Each app opens, does its job, and gets out of the way.

  • One maker, one spine

    The same person writes the code, designs the screens, and answers the support email. Consistent opinions, all the way down.

  • Works on older phones

    Offline-first, battery-conscious, and tested on modest hardware. The apps don't assume you bought a phone this year.
