Free while in beta
Build for yourself.
For you, your team or your community.
Build anything you want. For you. Your data, your control.
AI made building easy. Getting it onto your phone is still hard.
App stores
Want a public listing, a review, and a developer account.
TestFlight and sideloading
Built for developers, not for your gym log.
A link in a group chat
Gets forwarded. You can't take it back.
Phinneas does that last mile: from the app your AI wrote to an app on your own devices, private by default.
How big it gets
From a gym log to your own WhatsApp.
Just you
Your own systems
- Gym log
- Reading list
- Budget
Your team
Tools only your team can open
- Team chat
- Client portal
- Standup board
Your community
A place that's yours, not a platform's
- Discussion board
- Members' app
- Event check-in
Chat, discussion, members only. Each person sees only what they should, and only the people you approve can get in.
Your data, your keys
It runs on your accounts. Not ours.
Bring your own database, email and cache. Your app's data lives there. Your keys are encrypted and never reach the app people install.

your data, in your database
Who it's for
For self-maxxers. People who build their own systems.
Most software is made for millions of strangers. This is for the tracker, the tool, the little system that fits exactly how you live.
Your AI does the work
Claude Code, Cursor or Codex connect with one key.
Is it ready?
An optional check tells you what's missing, in plain words.
You approve devices
Every new phone or laptop waits for you.
Take it back anytime
Turn someone off and the app locks on its next check-in.
Updates arrive
Small fixes install themselves. Big ones ask first.
Your own services
Email, database and cache on your accounts, keys encrypted.
Where it runs
Every device you own.
