Support — Liquid Calm

A quiet place to put a finger.

Something wrong, or a question? Write to admin@utrendtek.com and a person will reply. Please say which device you are using and what happened.

How it works

The screen starts dark. Touch it and light appears where your finger is, threading outward, then slowly fading back to dark when you stop.

There is nothing else to learn. No score, no timer, no levels, no way to lose.

Common questions

How do I change the colour?

Tap one of the four dots along the bottom of the screen. Each one is a different world with its own colours, pace and sound.

Where are the settings?

Tap the small dim dot in the top-right corner. It asks you to solve a multiplication problem first — that is deliberate, so that a child cannot change the settings by accident.

Behind it you will find sound, vibration, calmer motion, higher contrast, and an option to lock the app to one colour.

There is no sound

Sound is off until you turn it on, and it is meant to be. Open the settings as above and choose Water or Tones. It fades in over several seconds rather than starting suddenly, so give it a moment.

Check your device is not on silent, and that the volume is up. On iPhone and iPad the app deliberately respects the silent switch and mixes with whatever else you are playing, so it will never interrupt your music.

Can I stop the colours being changed?

Yes. In settings, turn on Lock the colour. The four dots disappear entirely, so the world cannot be changed until you unlock it.

It does not vibrate

Vibration is off by default. Turn it on in settings, choosing Soft or Medium. Some older devices cannot vibrate gently, and on those the app stays silent rather than giving you a hard buzz.

Does it work without internet?

Always. The app makes no network requests at all, and on Android it does not even ask for internet permission. It works on a plane, underground, anywhere.

Is there anything to buy inside it?

No. You pay once and that is the whole transaction — no subscription, no in-app purchases, nothing locked away.

Schools, clinics and therapists
