v2.9.1

Download one APK and open it on the phone. Nothing else is needed —
no computer, no adb, no account.

• offline — start here. No INTERNET permission at all, so
  Android will not give it a network connection whatever its code
  asks for.
• online — only if you want translation or GIF search.

Then turn it on under Settings → System → Languages & input →
On-screen keyboard. Full instructions, and how to check what you
downloaded, are in the
README.
