Electronic Clock is a minimal full-screen digital clock — and a way to give the old phone in your drawer a second life. Plug an old phone or tablet into power, open Electronic Clock, and it becomes a big clock for your desk, nightstand or wall, with the local weather on screen too. Instead of letting an old device gather dust or end up as e-waste, put it back to work — and skip buying another clock. Time and weather at a glance: large hours and minutes fill the center of the screen, with seconds and a weather emoji right beside them, and the date, weekday and local temperature along the top. No unlocking, no opening other apps — one look tells you the time, the temperature and whether you need an umbrella. Ideas for an old device: • An old iPhone as a bedside clock, a retired iPad as a living room or kitchen clock • A spare phone on your office desk, in the entryway or at a shop counter • Second-hand phones, backup phones and hand-me-downs all find a use Features: • 12-hour or 24-hour clock that updates every second — set automatically for your region • Date and weekday at the top, with the weekday in English, Chinese or Japanese • Seconds and a weather emoji next to the time • Optional: uses your location to show the local temperature (°C or °F) and conditions • Weather data from MET Norway's public API — free, no ads • Choose the font, text size, text colour and background colour, or pick a built-in style preset • Celsius or Fahrenheit, matched to your region by default • App available in English, Traditional Chinese, Simplified Chinese and Japanese • Landscape full-screen layout on a black background by default; text scales to fit iPhone and iPad • Keeps the screen awake and hides the status bar for a clean display Optional Pro (one-time purchase, yours forever): • Custom colours for text and background • 5 extra fonts and 6 extra style presets • Flip clock animation Privacy: No account, no ads, no analytics, no developer servers. Location permission is optional; if granted, coordinates are rounded to about 1 km and sent only to MET Norway to look up the weather — never stored or tracked. See the privacy policy for details.
