Android

Toshokan on your phone

The Android app is finished and working; it is waiting in the Play Store queue. Until it clears, you can install it directly from here. Same app, same account, same studies.

Why not the Play Store?

It is coming — the listing is in review. Review takes as long as it takes, and there is no reason to make you wait for a paperwork queue when the app is ready. This is an early build, handed out directly while that queue moves.

Moving to the Play Store later

This early build is signed with a test key, and the Play Store release will be signed with a different one. Android will not upgrade an app across two different signatures — so when the store version arrives, you will need to uninstall this one first and install the store copy fresh.

Your account, your studies and your highlights all live on the server and come straight back when you sign in. What does not survive the uninstall is what is only on the device: downloaded translations, which you can simply download again.

Installing it

Android is cautious about apps that did not come from the store, so it will ask you to confirm twice. That is the system working correctly, not a sign that something is wrong.

  1. 1Tap Download the APK above. Chrome will warn you that this kind of file can harm your device — that warning appears for every APK, signed or not. Choose Download anyway.
  2. 2Open the downloaded file, from the notification or from Files → Downloads.
  3. 3Android will say the browser is not allowed to install unknown apps. Tap Settings on that prompt and switch on Allow from this source. You are granting permission to the app you downloaded it with, not to Toshokan.
  4. 4Come back and tap Install.
  5. 5Open Toshokan. You can turn Allow from this source back off afterwards — it is not needed again until the next update.

Making sure it is really us

Download it from this page only

This is the only place we publish the APK. If you find a Toshokan APK on a mirror site, an APK aggregator, or in a forwarded message, we did not put it there and we cannot tell you what is in it.

Checksum

If you want to be certain the file arrived intact, its SHA-256 is:

Updates are manual, for now

An app installed this way does not update itself. When there is a new version, come back to this page and install it over the top — your account, your studies and your downloaded translations all survive the upgrade. Once the Play Store listing is live, updates arrive on their own.

What is in this build

  • Ten translations. The King James text is bundled — it reads offline out of the box; the rest download on demand.
  • Strong's lexicon on the King James text, with a full concordance for every word.
  • The Scriptorium: write studies, embed passages by typing a reference, export to PDF.
  • Studies sync across your devices; drafts stay private until you publish them.

The guide walks through all of it in detail.

iPhone

Not yet. Apple has no equivalent of this page — an iOS build has to come through the App Store, so it will arrive when it arrives.

Any browser

Toshokan runs in full on the web, on a phone or a desktop, with the same account and the same studies. Nothing is held back for the app.
