Future Note is an iOS app for sealed letters to your future self. Write a note, lock it until a date you choose — no peeking, no editing — and when it returns, reply to the version of you who wrote it. Both letters live on a private timeline. Free to start.

Hey Product Hunt 👋 There's something quietly magic about writing a note to your future self. You put down who you are right now, the fears, the hopes, the small things you swear you'll never forget, and you hand it to someone you haven't met yet. I got a little obsessed with that feeling and went looking for a good app to do it properly. Honestly, I couldn't find one I loved. Most were just a scheduled email, or they let you edit the past, which quietly kills the whole thing. So I started building Future Note for myself. And somewhere in the middle of building it, the real idea showed up. What if, when a note comes back, you could reply to the version of you who wrote it? Both letters sitting side by side. And over time, those sealed notes become a timeline, a record of who you were on the days you were honest. That reply moment is the part that still gives me chills, and it's the main thing that makes Future Note different from everything else out there. It's not a mailbox. It's a conversation with yourself, across time. It's on iPhone, private by default, free to start. I'd genuinely love to know: what would you write to yourself a year from now, and would you want to write back when it returns? Markas, building slowly from Vilnius

Love the sealed letter idea, especially being able to reply to your past self. One thing that would make it stick for me: a gentle nudge a few days before a note unlocks, so I actually remember to come back and read it. Right now I might miss the moment and the reply could slip by.

Love this concept, the no-peeking rule is what makes it meaningful. One idea: add a gentle prompt a few days before the seal opens, like a notification nudging you to reflect on where you were when you wrote it, so the reply feels more intentional when the letter finally unlocks.
