COMPARISON
Looking for a Slowly alternative?
Slowly built the category. Here is where Snailpost genuinely differs — no charge per letter, translation on arrival, no popularity metrics — and where Slowly is still the better pick.
If you are searching for a Slowly alternative, you already know what a slow letter app is — and something about the one you are using has stopped fitting. Usually it is one of three things: writing started to feel rationed, the community started to feel like a scoreboard, or the app got busier while you wanted it quieter.
This page is written by the people who build Snailpost, so treat it the way you would treat any brochure — read the criteria, not the conclusion. What follows is the checklist we would use ourselves, the honest case for staying where you are, and the alternatives that are not us.
THE SHORT VERSION
- Every app in this category delivers by real-world distance. That is the category, not a differentiator.
- The real differences are rationing, popularity metrics, translation, and how people are introduced to each other.
- Snailpost never charges per letter, publishes no follower or like counts, and translates letters on arrival. Sending is capped at 10 letters and 7 new pen pals a day to keep spam out.
- Slowly pioneered this idea and is still a good app. If it is working for you, there is nothing to fix.
DELIVERY IS A FUNCTION OF DISTANCE
Every app in this category shares this one idea. The differences are everywhere else.
What a Slowly alternative actually has to get right
Distance-based delivery is the easy part — it is arithmetic on two coordinates, and every app here does it. What separates them is everything that happens around the letter: whether you can write as much as you want, whether the app keeps score, and what happens when a correspondence crosses a language.
A letter app is not judged by how fast it delivers. It is judged by how often you want to write the next one.
That is the metric worth optimising for, and it is why the checklist below is about friction rather than features. Every item is something you can verify yourself in about ten minutes, in any app, before you invest six months of correspondence in it.
SEVEN QUESTIONS WORTH ASKING
- Is writing metered or rate-limited?These are different things. A daily anti-spam cap is fine; being sold more capacity is not. Find out which one you are looking at.
- What does the free tier actually do?Free should mean you can write, receive and keep your letters — not a trial of the real thing.
- Is there a popularity score?Follower counts and like buttons turn correspondence into performance. Check whether any number is public.
- What happens across languages?Translation on arrival is the difference between a global community and an English-speaking one.
- How are people introduced?Matching on interests and languages surfaces different people than matching on a profile picture.
- How fast can you block someone?Report and block should be two taps from any letter, with a human reviewing serious reports.
- What happens to your letters if you leave?Look for a real delete path — account, letters and photos — not a hidden support ticket.
How Snailpost answers each one
Here are our own answers, in the same order. We have deliberately described only our own app in the specifics column — competitors change their pricing and limits often enough that any table claiming otherwise goes stale within a season, and a stale comparison is worse than no comparison. Check the others against their current app listing.
| The check | Snailpost |
|---|---|
| Is writing rationed? | Rate-limited, not metered. Up to 10 letters and 7 new pen pals a day — anti-spam limits that protect the community, not a paywall. Letters have no length limit, nothing you write costs a credit, and no cap lifts if you pay. |
| What does free actually do? | Everything core. Writing, receiving, matching, stamps and the letter journey are all free. Snailpost Plus adds extras, not the app. |
| Is there a popularity score? | No public numbers at all. No likes, no followers, no view counts. Nobody can tell how popular you are, including you. |
| Across languages? | Translation on arrival. Write in yours, they read in theirs. Optional, per letter. |
| How are people introduced? | Genuine profiles and introduction letters, plus kindred matching on shared interests and languages — not on a photo. |
| Blocking and reports | Two taps from any letter or profile. Automated screening for scams and serious abuse; child-safety reports treated as urgent. |
| Leaving | Settings → Delete account removes your account, letters and photos. There is also a step-by-step guide. |
When you should stay with Slowly
Slowly built this category. It proved that people would wait days for a message in an era built entirely around not waiting, and every app here — ours included — exists downstream of that idea. Three honest reasons not to move:
- You already have correspondents there. This is the big one. A pen pal you have written to for two years is worth more than any feature comparison. Correspondences do not transfer between apps.
- You like the stamp economy. Collecting is a real pleasure, and if earning and spending stamps is the part you enjoy, an app that removes the constraint removes the game with it.
- Its community is larger. A bigger pool means more people in unusual places and unusual languages. We are honest about being younger and smaller.
If the app you have is working, keep it. Look for an alternative when something specific has started to annoy you — and then check for that specific thing.the actual advice
The alternatives that are not apps
Worth saying plainly, because for some people this is the better answer:
- Postcrossing — real postcards to random addresses worldwide. Genuinely physical, genuinely random, and free apart from postage.
- Letter-writing societies and local clubs — slower still, and paper the whole way. Best if the object matters as much as the words.
- A private email thread with a rule. No app required. Agree with one friend that neither of you replies for a week. Most of the benefit of a slow letter app comes from the constraint, not the software.
We would rather you found the right one of those than downloaded ours and stopped writing after a fortnight. If you do want an app, though, here is the honest pitch: Snailpost is free, never charges per letter, translates on arrival, and keeps no score. It caps sending at 10 letters and 7 new pen pals a day, which is a spam limit rather than a sales tactic — if you are regularly writing more than ten letters in a day, you are not really using it for correspondence. It is on iPhone and Android.
Questions people ask before switching
What is the best Slowly alternative?+
It depends what pushed you to look. If you left because writing felt metered — capacity you had to earn or buy — look for an app that does not charge per letter; Snailpost never does, though it does cap sending at 10 letters and 7 new pen pals a day to keep spam out. If you left because the community felt like a popularity contest, choose an app with no public follower or like counts. If you want paper rather than a screen, a postal exchange like Postcrossing or a local letter-writing society is a better fit than any app.
Is Snailpost free?+
Yes. Snailpost is free to download and free to write with, on both iPhone and Android. There is no charge per letter and no length limit. Sending is capped at 10 letters and 7 new pen pals a day — an anti-spam limit that applies to everyone rather than a paywall. An optional Snailpost Plus subscription adds extras, but writing, receiving, matching and stamps are not behind it.
Do letters really take days to arrive?+
Yes, and that is the point. Delivery time is calculated from the real-world distance between you and your pen pal. A letter to someone in your own city can land within the hour; one crossing continents takes a day or two. The wait is what makes a letter feel like an event instead of a notification.
Can I write to someone who speaks another language?+
Yes. You write in your language and your pen pal reads in theirs — letters translate on arrival when you want them to. Language is never the reason two people do not meet.
Is Snailpost a dating app?+
No. Friendship is the default and there is no swiping. A correspondence can become personal if both people genuinely want that, but the app is not built as a marketplace, and reporting, blocking and consent matter throughout.
How do I move my pen pals to a new app?+
You cannot export a correspondence between apps, so the practical move is to write one last letter in the old app with your new handle in it. Anyone who genuinely wants to keep writing will follow; the correspondence matters more than the address it arrives at.
