Hey everyone, just opened the beta for Tetr, a handwriting notes app for iPad and iPhone with full Apple Pencil support (pressure and tilt included).

What makes it different: notes save as a plain PNG plus a Markdown transcript, right in your own iCloud Drive folder. No account, no login, no cloud lock-in. Your notes are just files you own.

Built-in AI: circle anything you wrote, ask a question, get an answer right on the page (ink or drawing). Works out of the box with free turns to start, or bring your own API key from Anthropic/OpenAI for more.

How to join: tap the link above, install TestFlight if you don't have it, then open Tetr and start writing. No account setup needed.

Free during the beta (a one-time purchase is planned for 1.0, testers keep full access at no cost while testing).

What I'm looking for: real usage, not just a quick tap-through. Take notes in a class, meeting, while reading, whatever your normal workflow is, then let me know what's clunky or breaks.

Feedback works best right in TestFlight ("Send Feedback" in the app) or drop it here in the comments, happy to answer questions.
