What gets listed

  • The developer is based in Brazil, and the app is built by one person (including a sole trader, MEI) or a small team.
  • Company products (LTDA and similar) go in the “Brazilian companies” section: the store shows a company with an address in Brazil.
  • It is on the App Store or Google Play, or it has a public web version or a public TestFlight link, so anyone can try it now.
  • The developer introduced the app in their own public post on Threads or TabNews. The line on each card is quoted word for word from that post in Portuguese, with an English translation below it. Tap the link to read the post.
  • Listing is free, and nobody can pay for a better position. Apps are grouped by category, not ranked: the order is shuffled on every visit, and categories with many apps show 3 random apps on this page each time. No star ratings, no ads, and store links are not affiliate links.

How the list is made

An AI agent read public posts on Threads and TabNews, found developers introducing their own apps, and checked each app against the developer details on the App Store and Google Play. Apps whose developer could not be confirmed to be in Brazil are kept on a pending list and are not shown here.

Prices, platforms, icons and screenshots come from the stores. The store page is the final word. Check it for in-app purchases, subscriptions and privacy before you install.

The English descriptions and quote translations were written with AI. The quotes themselves are the developers' own words, in Portuguese.

Are you a developer? To be listed, to correct something or to be removed, email hello@tidyfact.com with your app's name and its store or website link.

Prepare your details with an AI agent (copy the prompt)

Paste this into your AI agent (Claude, ChatGPT and so on). It gathers the details using the criteria on this page and drafts the email to us. You check it and send it yourself.

Please help me prepare an email asking TidyFact to add my app to its list of apps by Brazilian indie developers (https://tidyfact.com/indie-apps/br/en/).

Criteria (all must be met):
1. The developer (a person or a team) is based in Brazil.
2. Anyone can try it now: it is on the App Store or Google Play, or it has a public web version or a public TestFlight link. Apps that need a sign-up, an invite or a closed test first are not listed.
3. The developer introduced the app in their own public post on Threads or TabNews.

Fill in every field below. If you cannot find something, write "none". Do not guess.
- App name:
- One sentence on who it is for (up to 15 words):
- App Store link:
- Google Play link:
- Web version or download page link:
- Developer's Threads or TabNews profile:
- Link to the post that introduces the app (the developer's own post, not someone else's recommendation):
- One sentence from that post, copied word for word in its original language (up to 120 characters):
- Evidence that the developer is in Brazil (for example the Google Play developer address, the store seller name, a CNPJ or MEI):
- Built by one person or a small team, or a company product:

Then draft an email to hello@tidyfact.com with the subject "Listing request: <app name>" and the details above in the body. Show it to me first. I will check it and send it myself. Do not send it for me.
