Keep in touch without texting. Write and draw digital letters with friends and family, on iPhone and iPad. Choose the paper, write, draw or type, add stickers, stamp the envelope and send. A whole letter, made for someone. Their very own place: a desk that feels like them, and papers, envelopes, stamps and stickers in every collection. Connected, not always on. No chat bubbles, typing dots or read receipts, just a mailbox flag when a letter arrives. Their independence, your boundaries. Only friends you approve, settings behind your PIN, no photos or videos, and letters can't be forwarded. Friends and family without the app write back by email, and their reply arrives as a letter: words only, with no links, photos or attachments. Desks, friends, letters and replies are free, with up to six desks in one account. Collections are optional one-time purchases, yours to keep. No ads, and we never sell personal data.
