Make the app
your own.
The best app for you might not exist yet. Start with something simple, then ask for what’s missing — right inside the app.

“Can you add a shopping list I can tick off at the store?”
Your shopping list is ready. Add an item, then tap to check it off.
You try it. You decide what stays.
Ask. Try. Keep. Repeat.
- 01
Say what you need.
A small tweak, a new feature, or something that needs fixing. Describe it in your own words, from the Coding page.
- 02
Try the update.
An AI coding agent makes the change. Mytheseus builds and signs an update for you to install and try on your Android phone.
- 03
Keep what works.
Keep the version you like, ask for another change, or cancel the trial. Your feedback shapes the next version.
Same app.
More you.
Like the ship of Theseus, an app can change one plank at a time. Mytheseus puts those choices in the hands of the person using it.
It’s an experiment in personal software: small apps that grow around actual needs, with a history of what changed and a say in what happens next.
Built for Android. Self-hosted. Preparing for an open-source release.
