Most focus apps ask you to watch a timer. This one asks you to practice, and shows you the time you got back. Choose an ambient space, set a block of focus, and let the session run. Your record stays private, kept on your device. Every session you complete becomes a quiet line in your ledger. A few minutes at a time, counted and kept, so the focus you practice adds up to something you can see. WHAT'S INSIDE - Immersive ambient environments for deep work, study, and rest - Focus sessions with a clear beginning and a clear end - A private ledger of the time you reclaim, kept on your device - Spatial audio built for depth, not stimulation - No feeds, no comparisons, no interruptions Settle in, stay a while, and watch the practice grow. Try Pro free for 7 days. Then US$5.99 a month or US$44.99 a year, shown in your local currency at checkout. Cancel anytime in your Apple ID Subscriptions. Built by CortexonQuant Labs Pty Ltd.
