Help and tips
How do I get full screen?
Tap the full-screen button or double-tap the clock. On iPhone, install the app first: tap Share, then Add to Home Screen, and open it from your home screen.
Why does my screen stay on?
While the page is open and visible, the site asks your device to keep the screen awake. If your browser does not allow it, set a longer screen timeout in your display settings.
Why is there no sound?
Browsers start sound only after a tap. Choose a sound with the sound button, check that your device is not on silent, and raise the volume.
How does the sleep timer work?
Pick 15, 30 or 60 minutes. The sound fades out gently at the end, and the clock stays on.
Will it drain my battery?
A screen that stays on uses battery. Keep your device charging at night and lower the screen brightness. The charcoal background and the slow movement are gentle on screens.
What is free?
The digital clock face and the waves sound are free for everyone, always. All 10 clock faces, all 8 sounds and the sleep timer are free for 3 days, then €1.99 per month.
Can I use it on several devices?
One subscription works on up to 3 of your devices on your home network. Sign in on each device with your email.
Does it work without internet?
Once installed, the clock opens without internet. A subscriber's full version keeps working offline for up to 7 days.
