Write a letter to tomorrow-you tonight — and the next evening, open it. Selfletter is your nightly letter across time: today's hopes, worries, and reminders, delivered to the person you wake up as. It's a diary that meets you the next day. Reflect on today on one side, write to tomorrow on the other, and seal the night. When evening comes again, last-night-you is waiting with a letter just for you. Some nights, write further ahead. Seal a letter in a time capsule that won't open for a week, a month, or years — a gift to your future self that arrives exactly when you need it. Over time, your letters fill a quiet year you can look back on. • Write tonight, read tomorrow — a letter from past-you, every evening • Time capsules — seal letters for weeks, months, or years ahead • A year of you — a calendar of your nights, plus "a year ago tonight" • Yours alone — letters live on your device and iCloud, fully private • Search every word, choose your paper, and fill in any night you missed Tonight's letter is waiting. Write to tomorrow-you — and see what tomorrow brings. Selfletter. A letter to tomorrow, every night. — — — Privacy Policy: https://gurshanmann246.github.io/selfletter-pages/privacy/ Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Terms of Service: https://gurshanmann246.github.io/selfletter-pages/terms/
