Folded is a quiet place to write letters to your future self. Write a letter, choose the day it should arrive, and seal it. Once sealed, it stays sealed. No editing, no peeking. The letter waits, and on the day you chose, it opens. Your letters live on a timeline. The ones arriving soon sit near the top, and the ones years away rest further down, each a small sealed envelope with its own wax seal. When a letter is delivered, you break the seal and read what you wrote. Everything stays on your device. There are no accounts, no cloud, and no analytics. Your letters are yours alone. Folded is free to use. Folded Plus is an optional subscription that adds envelope customization (five paper colors, five seal colors, and a short inscription) and a 30 second voice note inside each letter, for $0.99 per month or $9.99 per year. Payment is charged to your Apple Account, and the subscription renews automatically unless canceled at least 24 hours before the end of the period. Manage or cancel anytime in Settings.

Some words are worth the wait. Tenderly lets you write letters to the people you love and seal them to be delivered on a future date — tomorrow, on their 18th birthday, on a wedding morning, or for the day they'll need them most. A time capsule for the heart. You write it today. They read it when it matters. WRITE TO THE PEOPLE YOU LOVE Not a letter to your future self — a letter to your daughter, your son, your partner, your parents. Pick the moment it should arrive, seal it, and let time do the rest. The countdown begins: "16 years remaining." THE MOMENT IT ARRIVES One day a quiet notice appears: a letter has arrived. Your words, written years ago, opened exactly when they were meant to be read. No printing, no shipping, no waiting on the mail — the moment of arrival is the keepsake. YOUR WORDS STAY YOURS Sealed letters are encrypted on your device with keys only you hold, so their contents stay private to you — even from us. Tenderly is local-first — it works offline and keeps your most intimate words between you and the person you wrote them for. DELIVERED EVEN IF YOU CANCEL Here is our promise in plain language: for as long as Tenderly operates, every letter you've already sealed will be delivered on schedule — even if your subscription ends. Delivery happens on your device, so a letter you've scheduled arrives whether or not you still subscribe. Your subscription pays for writing new letters and family features, never to hold the letters you've already sealed. Once it's sealed, it's on its way to them. A KEEPSAKE FOR EVERY DAY Between the big moments, keep a private journal for the people you love — small notes, photos, and reactions you can choose to share with family. A warm, private space with no public feed and no strangers. NEVER FACE A BLANK PAGE Gentle prompts help you start: "Write to them for their 18th." "What do you want them to know?" The hardest part of any letter is the first line — Tenderly hands you one. TENDERLY PREMIUM - Unlimited sealed letters, media, and shared family journaling - 7-day free trial on the annual plan - Free tier includes 1 sealed letter so you can feel it before you decide Tenderly Premium is an auto-renewing subscription. Payment is charged to your Apple ID at confirmation of purchase. It renews automatically — $39.99/year (with a 7-day free trial) or $6.99/month — unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings.

Tenderly is a Lifestyle app for keeping in touch across time. It is not a medical, clinical, or health product.
