The closed test

Help test Granger before it reaches the store.

Granger is an offline library for Android. Before a new app can go on Google Play, Google asks for a closed test: a group of people who install it and keep it for two weeks. We'd rather have your eyes on it anyway.

What you need

  • An Android phone (Android 10 or newer) with a Google account on it.
  • Wi-Fi and some space. The app is about 50 MB; the suggested starting library is about 9 GB. You choose what to download, and nothing downloads over mobile data unless you say so.
  • Two weeks. Google counts testers who stay opted in for 14 days in a row. You don't have to use it every day, just keep it installed and stay in the test.
  • For Ask, the librarian: a phone with 6 GB of memory or more. On smaller phones it's hidden and everything else works.

How to join

The test opens in the next few days. Send the email address of the Google account on your phone, and you'll get the link the day it opens.

What to try

  1. The first run. Pick a start, your region and what you'll use it for. Did the choices make sense?
  2. Get something and read it. A Wikipedia pack, a guide (Wikivoyage, iFixit, first aid), or a book from Granger Classics. Then search for something you'd actually look up.
  3. Turn on airplane mode and use it. That's the point.
  4. Listen. Open a book or an article and tap Listen; the owl reads it aloud. Try it with the screen locked.
  5. Ask (on 6 GB phones). Get the model under Settings → Models, then ask a question your library should answer. Tap a source to see where the answer came from. Ask is a preview: it's slow, and it can be wrong. Wrong answers are some of the most useful things you can send.
  6. Home. What does it show you, and is any of it useful?

Telling us what you found

Settings → Send feedback. Granger shows exactly what it will include (your phone model, Android version, free space, how many packs and books; no titles, no searches) and any crash reports, which you can read first or leave out. Then it opens your own mail app. Nothing is sent unless you send it.

Screenshots help. So do "I didn't understand this" and "I gave up here". Spanish is as welcome as English.

What we keep of you

Nothing. Granger has no account, no analytics and no tracking (the privacy policy). The testers group shows the address you joined with to the person running the test, and to no one else. Testers are never named anywhere.
