Just start typing on the numpad — the clock turns into a calculator. C on 0 (or ten idle seconds) returns to the clock. The 2nd key reveals %, √, ± and the memory keys. Turn the Crown to scroll your calculation history and tap a result to recall it.
Swipe to the CA-90 face — it opens as a watch. Tap to start, steer the ship with the Digital Crown, tap to fire (every shot beeps, hit or miss). Three landed UFOs end the game; long-press returns to Time mode.
watchOS returns to its own face after a delay. On the watch: Settings → General → Return to Clock, scroll to the app list, choose LCD-84 → Return to App / After 1 Hour.
The weather block needs location access: on the watch, Settings → Privacy & Security → Location Services → LCD-84 → While Using. A first fetch can take a few minutes; the app retries automatically.
Open the iPhone app, tap any item marked PRO, then Restore Purchase on the sheet. The unlock is tied to your Apple Account and works on all your devices.
Tap the display for a 6-second EL glow. Key beeps and the backlight color are configurable in the iPhone app's Customize tab; Silent keeps the haptics without sound.
