Editor's Overview

PTO - Plaintext Organizer is a note application developed by ferreum, packaged as a single Android APK of version 3.5 weighing in at 1.63 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

  1. Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
  2. File size is a light 1.63 MB, so it installs quickly even on modest connections.
  3. This build is signed by "ferreum" — always verify the developer name matches what's listed on the app's official store page before installing an update.
  4. After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
  5. We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

Origin

This is a (now distant) fork of billthefarmer's Diary: https://github.com/billthefarmer/diary

PTO has a lot of internal and UI changes. It focuses on usage as a general organizer instead of a Diary, though it can still be used as such, if you don't need the removed features. Most notably the markdown view has been removed, so no inline media can be displayed.

See the help file for more differences: https://gitlab.com/ferreum/pto/-/blob/master/app/src/main/assets/help.md#origin
