Real-time family location, driving alerts, and one-tap SOS — without the spyware vibes.
Indie mobile app studio · made in India
Trei builds calm, focused mobile apps for the everyday — family, pets, relationships, and the small things that add up. No bloat, no tracking theatre, no noise.
Each one solves a single problem, then gets out of the way.
Real-time family location, driving alerts, and one-tap SOS — without the spyware vibes.
Minimal Android launcher focused on simple navigation and essential apps.
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.
No third-party trackers, no ad networks, no data resale. The analytics we keep are the ones that help us fix bugs.
No streaks to protect, no red badges, no manufactured urgency. Each app opens, does its job, and gets out of the way.
The same person writes the code, designs the screens, and answers the support email. Consistent opinions, all the way down.
Offline-first, battery-conscious, and tested on modest hardware. The apps don't assume you bought a phone this year.
