Hi all,<p>tetr has been my solo passion project for more than 2 years now ever since I got a craving to expand something like the Note to Self feature I have been using on Signal to an entire ecosystem. It’s not just a barebones chat but a customizable chat UI-based productivity system (at least that is the end goal) with advanced features like scheduling routine messages to be sent to you at a specific interval.<p>I recently went through a multi-month rewrite moving from Realm to SQLite to prepare for end to end encrypted sync (sadly not ready yet) and adding a handful of quality of life improvements like biweekly routine reminders.<p>Let me know what you think; it’s only on iOS, iPadOS and Mac (though as a universal app) but I’m looking to expand to Web and Desktop platforms soon and eventually Android so hopefully that’d let more people to test it out!
