About this app
Heirloom lets you write letters to your future self — and locks them until the moment you chose. Write a letter today. Set a delivery date months or years from now. When the time comes, Heirloom delivers it to you like a message from the past. TIME CAPSULE LETTERS Seal a letter and set a countdown. Heirloom locks it until your chosen date — whether that's your next birthday, a graduation, or five years from now. A live countdown reminds you something is waiting. PHOTOS & VOICE Attach a photo or record your voice. Your future self will hear how you sounded, see where you were, and remember exactly how it felt to be you right now. MOODS Tag each letter with how you're feeling: hopeful, excited, calm, anxious. See the emotional arc of your life as your collection grows. NEVER MISS A LETTER Heirloom notifies you the moment a letter is ready to open. No account required — your letters arrive on the device you carry every day. TIMELINE VIEW Browse your letter history in a calendar. See which days had something worth saying, and revisit them anytime. ON THIS DAY Each time you open the app, Heirloom surfaces letters from past years that were written on today's date — like a private anniversary. COMPLETELY PRIVATE No account. No cloud sync. Your letters live only on your device. Start with one letter. Write to yourself one year from now. You'll be glad you did.
