Apps like Slowly
The short answer: if you like Slowly’s delayed letters, the closest alternatives are other slow-letter pen pal apps. If you want real post, Postcrossing; for quick chat with people abroad, InterPals; for a message-in-a-bottle style app, Bottled. Hasty is a newer, adults-only slow-letter app.

How Hasty differs from Slowly
Both apps deliver letters after a delay based on distance, and both have stamps to collect. Hasty is adults-only, has no ads, lets you write a lost letter to anyone, and has a blind exchange for swapping stamps and postcards. Letters never take more than two days.
Which should you choose?
- You want real paper post: Postcrossing, or a pen pal website that offers postal penfriends.
- You want to practise a language fast: a language-exchange app.
- You want slow letters with other adults: Hasty.
