Android app

The same dictionaries as on the site — the whole set inside your phone. The database ships with the app, so search works on a plane, underground, anywhere with no signal.

How to install

  1. Download the file

    On your phone, tap the button above — the browser saves the APK to Downloads.

  2. Allow the install

    The app is not from Google Play, so Android asks your browser for permission once. That prompt is normal.

  3. Wait for the unpacking

    On first launch the dictionaries unpack for about a minute. After that the app opens instantly.

About safety

The app is not on Google Play yet — publication is being prepared, and until then the file is served straight from this site.

Every build is signed with the same key. Certificate fingerprint (SHA-256):

29:B2:B6:91:8D:82:E1:7B:39:04:16:9F:BE:E9:E0:78:92:F6:A8:80:B6:47:CA:1C:58:66:E1:C8:F4:E4:97:59

The app shows no ads and does not track you. What it stores is described in the privacy policy.

What about iPhone?

An iOS version is in progress — stay tuned.
