SlipStitch

A studio for native apps

Small apps,
finished properly.

SlipStitch makes native apps for iPhone, Android and the watch. Each one is complete without an account, honest about data, and tested to a bar most apps skip.

See the apps hello@slipstitch.dev

Why the stitch

A slip stitch is the one you pass along unworked, so the fabric lies flat and the join never shows. The work you do not see is what holds.

That is our idea of quality. The tests, the privacy work and the release discipline are invisible in the app. You feel them anyway.

The apps

How we build

  1. Native and local-first

    SwiftUI, Compose, both watches. Your data lives on your phone. The app is complete without an account; an account only ever adds sync.

  2. One verified core

    Where there is logic worth getting right, it lives in one Rust engine that every platform shares, with property tests, formal proofs and a mutation score that may only go up.

  3. Private by default

    No ads. No trackers. We never sell data. Crash reports carry no personal data and analytics are anonymous, in the EU, with a switch to turn them off.

  4. No shame, no dark patterns

    Nothing nags, counts your failures or hides what you logged when you stop paying. "Not now" is always on the screen.

  5. Written down

    Every app ships with its own privacy assessment, security review and release runbook. If we cannot write it down, it is not finished.

  6. Finished properly

    Screenshots tested on every platform, copy checked against a list of words we will not use, and a person does the last step of every release.
