Lettre

Build friendships through digital letters and collectible stamps

Meet Lettre

Lettre is a digital letter-writing app for iPhone and iPad that gives conversations the feel of exchanging personal mail. Users can write to friends or find penpals around the world, taking time to compose a letter instead of maintaining a constant stream of short messages.

The app includes papers, envelopes, stickers, and digital stamps created by independent artists. Stamps can be collected and traded, adding a shared creative activity to the correspondence. Its penpal community helps people discover others with common interests and begin new friendships. Lettre offers free access alongside an optional membership that supports the app and unlocks additional perks.
