Private & Local-First
tetr works completely offline: it does not store your messages on any server and instead just saves them on your device. We do not and will never sell your data.
Message yourself and quickly capture…
Notes: capture thoughts, ideas, and more in a familiar, casual chat-based interface.
Tasks: manage shopping lists, chores, and get reminders for important things.
Journaling: track your mood and thoughts in a private space.
Links: save links and articles for later and create collections of your favorite content.
Community-Supported
tetr is a fully independent app. We do not have external investors and the pressure to hyper-grow which dominates the tech field. We grow with the support of the community of like minded technologists, indie hackers, and makers.
This is a fantastic, easy to use app for reminders, daily routines, and logs. I use it every day and rely on it to remind me for taking my meds, my appointments, birthdays, etc.

It is easy to journal when you text yourself. There is less pressure to stick to a format and make it pretty. I use this app more than others because of its simplicity, reminders and routines.
