There are things you mean to say and never do. Will makes sure they get said anyway. Write a message to the people who matter. Choose who receives it. Then get on with your life. Once a month, Will asks you to confirm you're still here — one tap. If you ever stop answering, your messages are delivered to the people you chose. That's the whole idea. No feed, no social network, no subscription required. HOW IT WORKS 1. WRITE A letter to your daughter for the day she turns eighteen. Where the will is kept and what the passwords are. The apology you never managed out loud. Write as many as you like. 2. CHECK IN Once a month we ask whether you're still alive. Answer in the app, from a push notification, or by tapping a link in an email. It takes a second. 3. DELIVERED Miss six check-ins in a row and Will sends each message to its recipients. Not a day before. WHAT'S INSIDE • Unlimited messages, free forever • Separate recipients for every message — nobody sees what was meant for someone else • A countdown showing exactly where you stand • Optional notice telling your recipients something is waiting, without revealing what it says • Push and email reminders, so you never miss a check-in by accident • Eight languages • Delete your account and everything is erased, permanently WILL+ — THE LIFE GRID Your whole life as a single grid: ninety years, one dot per week. Fill the weeks that mattered with photos, video and voice recordings — 50 GB of them — and they are handed to your people after you're gone, together with your messages. Choose who sees what: everyone, or only the people and groups you pick. Everything is kept for your heirs for ten years after release, and they don't need an account to open it. Text memories are free. Will+ adds the photos, video and voice. PRIVACY Your messages are readable by you and nobody else until the day they are released. We don't sell data and we don't show ads. Delete your account at any time and all of it disappears with it. Will is free. Will+ is optional.
