Laterr is a simple tool that delivers a message to your future self. You write something, a reminder, a goal, a note, pick a date, and Laterr sends it to you on that day by email (free) or phone call.

No account needed. No app to install. You type your message, choose when you want to get it, and that's it. It shows up in your inbox or rings your phone on the day you picked.
