About this app

Roost brings back old-school messaging with carrier pigeons, snail mail, and now handwritten letters.

We call it Slowcial Media!

Write a letter in your own handwriting, choose a courier, and send it across the world. Your bird picks it up, flies to its destination, and delivers it when it gets there. No instant delivery. No read receipts ten seconds later. Just a little bird carrying your words, taking the time it takes.

Make pen pals around the world, send letters to your friends, collect birds, and build your own little rookery along the way.

YOUR HANDWRITING, YOUR LETTERS

Turn your handwriting into your own font and write letters that actually look like yours. Personalize your letters with animations and make something a little more special than another text bubble.

PEN PALS AROUND THE WORLD

Meet people from other countries, make new friends, and learn about life somewhere else.…

I wish I had more room write a review! This is fantastic! No ads just pure fun with birds and finding people across the world! Or have fun with messaging your own friends too, like I'm doing! And incredible concept that I think is…

Awesome app, awesome features. No ads whatsoever.

5★ · Google Play · 2026-10-12

A sampled review illustrates one person’s experience. It does not establish a finding on its own.

Measurements

5 measured · 3 not assessed

Supporting measurements. They are not a complete list of possible harms or positives. “Not assessed” means we could not measure it — never zero, never a pass.

Themes reported by reviewers
No theme reported
Counted from the reviews we have read for this app. "No theme reported" means no theme reached our reporting threshold — it is not a finding that nothing is wrong with this app, and we do not say it is.
Five-star share of ratings
80–89% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.

In the app package we scanned

No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.

Method and limits

What this report can and cannot show

How a review signal works

A review signal is produced automatically from public app reviews by a classifier — never by a hands-on Appworthy test, and never by a human analyst. It exists so a real, not-yet-audited app can carry more than a blank “Not yet tested” listing, without ever being mistaken for an assessment.

A theme only appears above once at least 5 distinct reviews corroborate it — one angry review can never tag an app. These thresholds are published settings and may be tuned as coverage grows.

It carries no confirmed findings — reviews are one kind of evidence, and nothing here has been hands-on tested. The moment Appworthy publishes a full assessment of this app, it replaces this signal, permanently.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review replaces this review-derived signal with hands-on, recorded measurements. Hands-on inspections are not yet open.
