Show HN: I built an app to text myself and get reminders, notes, journal, etc.

I started this around 2 years ago to explore my love for using apps like Signal for notetaking and its potential to extend this to so much more.<p>tetr lets you create checklists, reminders, notes &amp; more through one familiar interface: chats (also known as Spaces). No fancy AI or internet needed, just an instant &amp; easy way to get your thoughts in. When you want it, you can also access your data in traditional views like your average todo app.<p>Currently available on iOS, iPadOS, MacOS as a universal app; end-to-end encrypted sync beta will be available soon.<p>Features:<p>* Offline-first: all on your device, with E2EE sync coming soon.<p>* Routines: set reoccurring texts to be sent to your Spaces and use them to build habits, get affirmations, and more.<p>* Calendar integration: text reminders &amp; see them in your device calendar right away.<p>* Share content &amp; links like you would to any other messaging app.<p>* Journal view &amp; mood tracking.<p>* Basic markdown support.<p>There&#x27;s still a lot to come, starting with sync and ending with a better desktop experience &amp; greater customization and extension options. Would love to hear what you think and feel free to ask about it!<p>Built with Flutter and Realm &#x2F; Atlas Device Sync (note I work on the sync SDKs at MongoDB but this is purely my personal project)
