How we build

Four rules we hold to

Constraints, not slogans. They are also the reason 6 of our 7 apps have no sign-in at all — and why the one that does explains exactly why on its own page.

  • 01

    Offline wherever it is possible

    If a feature can run on your device, it does — no spinner waiting on a server. Where something genuinely needs one, such as speech synthesis or live exchange rates, we say so plainly instead of hiding it.

  • 02

    No sign-up without a reason

    Most of our apps have no account at all — you open them and start working. The one that does needs it to sync your progress across devices, and nothing else.

  • 03

    Every SDK named

    Each app has a full privacy policy listing every third-party SDK it contains, what that vendor can see, and how to opt out. No "we may share data with partners".

  • 04

    Built to feel fast

    Native Kotlin and Jetpack Compose, Material 3, and a hard budget on every interaction. No web views pretending to be apps.

Have an app that should exist?

We take on a small number of outside projects. If you have something focused in mind — a tool, a utility, something that ought to be simpler than it currently is — tell us about it.
