The Slowletter approach
Why people switch to Slowletter
Interest-based matching, not random
Slowly delivers based on distance. Slowletter reads what you care about and finds someone who cares about the same things. The connection starts meaningful.
No stamps, no coins, no premium gates
Slowly uses a virtual stamp economy. Slowletter has no premium currency. You write a letter, it reaches your match. That is it.
Anonymous until you are both ready
On Slowly, your avatar and username are visible from the start. On Slowletter, identity is revealed only after mutual acceptance. Words come first.
Letters that lead to real conversation
After enough letters, Slowletter unlocks real-time chat. Slowly stays letter-only. Sometimes you want the flexibility to text your friend without waiting.
Quality over quantity
Slowly encourages collecting stamps from many countries. Slowletter encourages depth with fewer, better connections.
Modern web app, no download required
Slowletter works in your browser on any device. No app store, no download, no storage. Just open and write.

FAQ
Frequently asked questions
No. Both are pen pal apps but they work differently. Slowly simulates postal delivery times based on distance. Slowletter focuses on letter quality and interest-based matching. Your letter reaches someone compatible, not just someone far away.
Absolutely. Many pen pal enthusiasts use multiple platforms. Different apps attract different communities and offer different experiences.
Some people find that Slowly's distance-based delivery and stamp collection system feel gamified. Slowletter is simpler: write a genuine letter, get matched to someone who shares your interests, and build a real connection.
No. Slowletter delivers letters when they are ready to be read. The slowness comes from the format itself, writing a real letter takes thought, and that is the point.
Yes, free to join and free to use core features. No stamps to collect, no premium currency, no paywall between you and your pen pal.
Bottled uses a message-in-a-bottle metaphor with random delivery. PenPal World is a directory where you browse profiles. Slowletter takes a different approach: you write one letter about what matters to you, and Slowletter matches it to someone whose interests align. No browsing, no randomness.
