Slowly review: what it is, who it's for
Pen-pal letters that take hours or days to arrive - the anti-instant option for people who want depth.

Open Slowly →
Slowly matches you with pen pals by interests and languages, and then it does something strange: your messages take time to arrive, based on how far apart you live. A letter to someone on another continent might take a day. That sounds like a bug and it's the whole design. People write longer, think more, and the conversations that survive are real ones. It's free, with a paid tier for extras like more stamps and slots.
What Slowly is
Slowly is a pen-pal app that deliberately refuses to be instant. You match with someone by language and shared interests, write a letter, seal it, stamp it, and then wait: the farther away your pen pal lives, the longer the letter takes to arrive. There is no swiping and no read receipts. The company is Slowly Communications Ltd., registered in London, and the terms say the service is for users 18 or older.
Why the delay is the feature
If random chat leaves you feeling emptier than before, the delay is the cure. A letter that takes a day to arrive gets written properly, and the replies are worth reading. Slowly's own stories page is full of multi-year friendships built this way, including pen pals who met after three years of letters.
Stamps and extras
Slowly turns the wait into a collection: over 2,000 stamps you earn by meeting new pals, having letters reach new countries, or logging in during holidays and events. There's a merch store and some in-app extras; the core of matching, writing and receiving letters is free.
Rules that matter
The terms prohibit misrepresenting your identity, age or affiliations, soliciting money, gifts, loans, visa help or jobs from other users, and harvesting personal information. That last set matters on a pen-pal app, where long correspondences build trust: if a pen pal asks for money or help with a visa, that's against the rules and a red flag. Slowly publishes safety tips alongside its guidelines.
Slowly against the alternatives
Slowly is the opposite of every other site here: slow, written, and built for depth. Wakie is voice and instant; Discord is community; the random-chat sites are the quick hit. If you want one real friendship rather than a hundred conversations, this is the one. Table below.
