App lock, reading mode and AMOLED theme

Three additions are rolling out to every ttdictionary dictionary app on Google Play. All three are on Android for now.

App lock

A dictionary is a personal thing: your own words, your notes, your favorites, the history of what you looked up. App lock keeps all of it closed on a shared or borrowed phone.

Turn it on in Settings and choose when the lock should apply:

• After 30 seconds in the background.
• After 60 seconds in the background.
• Every time the app is fully closed — the lock is asked for on the next launch.

There is no new password to invent or remember. The app uses Android's own device lock, so you unlock the dictionary exactly the way you unlock your phone: PIN, pattern, password or the biometric method your device is already set up with. The app stores nothing of it and sends nothing anywhere.

Reading mode

Reading in a dictionary is rarely one line — a full definition, the examples, your own note underneath. Reading mode replaces the bright white background with a warm, paper-coloured one. Less blue light, less glare, and a page that is easier on the eyes in the evening and during long sessions.

AMOLED theme

Next to it there is now a pure-black theme. On OLED and AMOLED screens black pixels are switched off completely, so the app looks deeper at night and draws less battery than an ordinary dark theme.

Both sit in Settings next to the existing light, dark and follow-the-system options, apply to every screen — search lists, word cards, notes, training — and take effect immediately, without restarting the app.
