When it all feels too much, you can start here. One tap on the light opens a guided pause of about 90 seconds: a short lead-in, breathing with the light, looking around and time to settle. It ends with one sentence for stepping back into your day. You can pause or leave whenever you want. A quiet room Skillhouette is dark and still. One warm light hangs low in the room and stays with you through the pause and the breathing exercises. Nothing flashes, nothing hurries you. 19 short activities Breathe in different rhythms, each with a quiet ending after about a minute and a half; optional 4-7-8 breathing remains a separate choice. Notice your body and surroundings. Draw lines in sand, touch bubbles or lay out patterns. Give your mind a small task, like counting backwards in steps. No pressure: no scores, no streaks, nothing to win. Private, paid once No account, ads or tracking. Settings stay on your device. A one-time purchase includes the guided pause and all 19 activities. No subscription or in-app purchases. Quietly adjustable The breathing sound starts off. With Less motion, the guided pause keeps moving through its steps without scaling animation; a manual mode is also available. Keep breathing lets you stay with the breathing guidance for longer. The optional check-in at the end is never saved. Safety information Help numbers for selected countries can be read offline, with sources and a check date. The list is incomplete and details can change. Calls need a phone connection; external links need internet. Skillhouette itself offers no counselling and is not affiliated with the listed services. Skillhouette is not a medical device and does not diagnose, treat, cure, or prevent any medical condition.
