Estimated revenue
A model estimate with a likely range, not a reported figure.
No estimate. Apps outside the grossing charts, and some countries, have no reliable rank-to-revenue curve, so we show nothing rather than a guess.
How this estimate is made
Rank: we take the app's best Top Grossing rank on the latest chart day. Category ranks are converted into an equivalent overall rank, because a #10 in Finance earns far less than a #10 overall.
Curve: that equivalent rank is read off a rank-to-revenue curve anchored on public company revenue and market-data reports for the US iPhone App Store.
Country: the curve is scaled per country (Japan is roughly a third of the US, Türkiye under 1%). Where we have no scale, such as China, there is no estimate.
Range: the likely range widens with country, category and chart depth. It is a plausible span, not a statistical confidence interval.
Not included: ads, payments outside the App Store, and any difference between gross sales and what the developer keeps. Low confidence means indirect data; medium means several independent sources agree.

About this app
Text from the App Store listing.
Chithi.me is a mailbox for letters worth keeping.
Share your link on social media, and the people who follow you can write you a letter. It arrives in its own handwritten font, on their choice of paper-like design, and it stays in your mailbox for as long as you want it there.
HOW IT WORKS
1. Share your Chithi.me link
2. The people you share it with write you a letter
3. It lands in your mailbox seconds later
WATCH THE WRITING TAKE SHAPE
Replay any letter keystroke by keystroke and watch it being written. It is the closest you will get to sitting beside someone while they write to you.
POST ONE TO YOUR STORY
Put a letter on one of your own photos and share it in a tap.
YOUR OWN QR CARD
Turn your link into a card people can scan. Pick a style, write a caption in Bangla or English, and share it as a picture. Point a phone camera at it and your letter page opens.
A MAILBOX THAT IS ONLY YOURS
Letters arrive grouped by day, so today's are on top. Search everything you have ever been sent. A notification tells you the moment one lands. Nobody but you can see your mailbox.
YOU DECIDE WHAT REACHES YOU
Letters arrive unsigned, so a friend can say the kind thing they would not say out loud. That only works if the mailbox is a safe place to open, so Chithi.me is built with the controls to keep it one:
- Every letter is screened by an automatic filter, in English and in Bangla, before it reaches you. The filter is on by default and you can turn it off.
- Report any letter in two taps. We review every report within 24 hours and remove anything that breaks our rules.
- Block whoever wrote a letter and nothing of theirs reaches you again. Blocked writers are listed in Settings, and you can undo it there.
- Delete any letter the moment you see it.
- Pause your link so it stops accepting letters, or delete your account and everything in it, from inside the app.
- We have no tolerance for abuse. Writers who break our rules lose access, and we act on reports within 24 hours.
- Reach us any time at [email protected].
Chithi.me is for people who miss getting letters. Share your link and see what arrives.

What’s new
Release notes for the latest version, as written by the developer.
- The retro paper is new. It used to be a yellow sticky note; it is now a blue airmail sheet with its own postmark, and the handwriting on it changed with it. Letters already written on that paper are shown on the new sheet.
- Your mailbox opens faster.
- Sharing a letter to your story keeps the writing at the right size on iOS 26.
