Guided breathing
Choose from several guided breathing techniques, including 4-7-8, box and coherent breathing, with a pulsing visual guide to follow.
Create your own breathing technique
Not happy with the presets? Build your own rhythm: set the inhale, the hold after inhaling, the exhale and the hold after exhaling in seconds (set a hold to 0 to skip it) and optionally give it a name. While you tune it you see the cycle length and breaths per minute. Save it and it starts right away and stays saved for next time.
Breathe together
Open the TOGETHER room in the breathing section and breathe 4-7-8 in the very same second as everyone else who is there. If you are the first, you breathe on your own and whoever joins later snaps right into your rhythm. You see how many people are breathing with you, can send a heart (SEND CALM) or invite a friend, and only an anonymous headcount is ever shared. Every evening at 21:00 Prague time there is a shared 10-minute session, with a calendar reminder you can download.
Gentle reminders
Turn on local reminders that nudge you to pause and breathe every 15 minutes to 4 hours — nothing is ever sent to a server.

SYNTHLUCIDA BLOCKS that unlocks music
Clear lines in a full SYNTHLUCIDA BLOCKS game to permanently unlock ASMR, piano and chill tracks — every 20 lines earns a bonus round and a bomb charge that instantly clears rows. Progress and visual theme are saved in your browser.
Interactive ambient night sky
Tap the night sky to play a generative synth, layer binaural waves and nature sounds, or build your own loops in a step sequencer. Set a sleep timer, record your session as a .wav file, and watch the sky shift with the real time of day and the actual moon phase.
Drawing canvas that comes alive
Paint with different brush feels, fill in coloring pages like mandalas and butterflies, or add stylised text and emoji. A soft ambient tone follows your brush as you draw, and marking a part of your picture lets you animate it — a wing that flaps, a star that twinkles — then replay or export it as video or GIF.
