Apps Like Slowly in 2026: Pen Pal Alternatives Compared

Slowly took an old idea, the pen pal letter that arrives days after it was written, and put it on a phone. You pick an avatar and a nickname, write a long letter, and wait while it "travels" to someone on the other side of the world. For many people that wait is the whole point.

The same slowness also frustrates people. This page covers the alternatives that still exist in 2026, and is honest about when Slowly is still the right choice.

Why people look for an app like Slowly

From Slowly's App Store reviews, a few reasons come up again and again:

1. Replies that take weeks, or never come. The letter itself takes hours or days, which people sign up for. What wears them down is the pen pal who answers a month later, or not at all. Reviews often mention forgetting what the conversation was even about.
2. Paid extras and prompts. The core is free, but some reviewers dislike the subscription screen during sign-up, and Slowly's Google Play listing now says the app contains ads.
3. Limits on new matches. Slowly's help center says matching is capped each day, and Auto-match can be used once a day.
4. The same problems every pen pal app has. Some reviews describe scam profiles or people looking for romance rather than friendship.

None of this makes Slowly a bad app. Some people just want a different pace.

What Slowly still does better

Before you leave, know what you'd give up:

• Delayed letters. Delivery time depends on real distance, so there's no pressure to reply in five minutes. You write when you have something to say.
• Stamps. Slowly says it has over 3,000 stamps to collect, unlocked by meeting new people, travelling or logging in during holidays and events.
• Avatars and anonymity. A nickname and a drawn avatar are all anyone sees. No photos, no real names on your profile.
• Matching by interest and language. Letters start from shared topics, which makes the first one easier to write.
• A generous free tier. Unlimited letters, profile browsing with filters, and many free stamps and avatars.

Stay on Slowly if you love the wait, enjoy collecting stamps, want to stay anonymous behind an avatar, and are happy to write long letters to a few people. If the only problem is a pen pal who went quiet, try a fresh open letter before you try a new app.

What to look for in an alternative

• Pace. Letters that take days, a message a day, or a live conversation?
• Privacy. Can you stay anonymous, and are photos required?
• Cost. What is free, and what needs a subscription or coins?
• No dating. Pick apps built around friendship, culture or language, and block and report anyone who isn't.

Letter-style alternatives

Global Penfriends

A pen pal site that has been running since the 1990s. You build a profile, search for people, and write through its online messaging or by real post. Members can join groups such as Language Exchange, Snail Mail Penpals and Mail Art. It's free to join: free members get a contact credit every 12 to 24 hours to start a new conversation, and a Premium membership removes that limit and the site's ads. It's the pick if you'd like real letters in your mailbox.

PenPal World

Another long-running pen pal website. It's free to join, with a paid VIP membership. You search members, add friends and leave comments, profile pictures are reviewed, and you can block a single user or even a whole country. It's search-and-message, so it feels more like a classic pen pal directory than Slowly's matched letters.

Lettre

The closest to Slowly in spirit. Lettre is an iPhone and iPad app built around handwritten digital letters, with stationery, stickers and a digital stamp collection made by independent artists. It says it has no ads, and an optional Pippin Supporters Club pays for it. It's lovely with an Apple Pencil. The catch: it's iOS only, so your Android friends can't join.

Something in between: Bottled

Bottled works like a message in a bottle. You write a message, it drifts to a random person, and if they keep it, you're matched and can chat. If they release it, it floats on to someone else. Once matched you can send text, photos and voice messages. It's free to use, with an optional Cruise membership, and its Google Play listing says it contains ads. It keeps a little of Slowly's chance and anticipation, without days of waiting for each reply.

If you want replies today: Olu

Olu is the opposite of Slowly in one important way: it's instant. It's a free, ad-free, text-only chat app for meeting people in other countries.

• One tap, a real person. You're matched with someone who is online right now. No waiting days to see if a letter landed.
• Every message translated both ways. Their words arrive in your language, and the original is always visible. You don't need a shared language to start.
• Themed planets. The language learners planet matches you with language-exchange partners first.
• The closest thing to a letter. If nobody is online, you can leave one message for a real traveller who is offline. It's translated, and if they reply, you're connected.
• AI chat partners, always labelled AI. They're never passed off as people.

Honest limits: Olu is instant chat, not slow letters. There are no stamps and nothing to collect. It's text only, with no voice or video calls. The community is small, so at quiet hours you may not find someone at once. Photos are optional.

Language-exchange pen pals

If you used Slowly mainly to practise a language, HelloTalk and Tandem are built for that. Both are free to download and let you look for native speakers to practise with, and HelloTalk lists translation among its learning tools. They're faster than Slowly, though reviews often mention first messages that go unanswered. See our HelloTalk alternatives and Tandem alternatives guides. If you're also weighing up InterPals, we compared it separately in InterPals alternatives.

Staying safe with a new pen pal

Whichever app you choose, the same habits protect you. Keep your address, workplace and full name to yourself until you really know someone (snail-mail sites have their own address-swap rules for a reason). Never send money, and be wary of anyone who wants to move to another app straight away. Our random chat safety tips go into more detail.

Which one to pick

• You love the wait, the stamps and the avatar: stay on Slowly.
• You want real paper letters: Global Penfriends.
• You want a classic pen pal directory to search: PenPal World.
• You have an iPad and love handwriting: Lettre.
• You want chance encounters that turn into chats: Bottled.
• You want serious language practice: HelloTalk or Tandem.
• You want to talk to someone in another country today, even without a shared language: Olu.

Plenty of people keep two: Slowly for the long letters, and something quicker for the days they want a conversation now. For turning either into a lasting friendship, read how to make friends from other countries online.
