Underground by astosia

There’s another cool watchface on the Rebble App Store!

astosia says:

Underground is a customizable, easy to read, large font watchface using the London Underground font.

Now with optional weather! Shake or tap to show weather for 10 seconds. Weather uses Open-Meteo, which doesn’t need an API key. If you prefer OpenWeatherMap, you’ll need your own OWM Onecall 3.0 api key and subscription: there is a free tier.

Features:

Auto-detection of 12h/24h based on your watch settings - Auto-translation of weekday supported for: English, Spanish, German, French, Portuguese, Italian.

Day & Date and Battery complications

Time shrinks down when timelime quickview is visible (on Time, Time Steel and Pebble 2)

Choose background and text colours

Bluetooth disconnect vibration warning and icon (can select whether there is a vibe or not during quiet time)

Quiet Time icon
Make the complications the same colour as the background to hide them.

Sunrise/Sunset time based on your current location (uses Suncalc, based on latitude/longitude from your phone’s gps or a manually entered location)

Go check it out in the App Store!
