What it does
Hasty is a penpal app where you write letters instead of chatting. You’re matched from a short self-description, and each letter travels for a few hours to two days depending on the real distance between your cities, shown as a loose estimate rather than a countdown. Stamps, postcards and anonymous lost letters make the wait part of the fun.
Adults who want slow, thoughtful letters with strangers around the world instead of instant messaging.
Features
- ·Delivery time from the real distance between cities, from a few hours nearby to about two days across the world
- ·Matching from a short bio, languages and interests, favouring shared interests and new countries
- ·Stamps, postcards from 137 cities and stationery to collect, with stamps spent on first letters
- ·“Someone, Somewhere” lost letters: anonymous letters to a random stranger
- ·Letter tools: paper and envelopes, a sealing step that shows the route and time, drafts, wax seals and photos the recipient approves
- ·Safety checks on every letter, reporting with automatic blocking, and a moderation site
