The exercise and timer beside the breathing shape

Anyone uneasy about location-based check-ins, though those features are optional.
Rana offers guided breathing, including SOBER breathing, box breathing and the physiological sigh, and learns from your ratings which ones help. You can check in on mood, cravings and HALT needs, keep a journal, save photos and reasons, and track progress and milestones. My Places maps confirmed reports and places that help, and optional reminders can prompt a check-in near alcohol or cannabis stores or late at night in isolated places, with that learning kept on the device. A supporter mode guides loved ones. It is free with no paywall.
On the iPhone Duo, Home, My Places, Journal and Progress adapt to the open screen: a larger map, the journal read beside its list, and breathing exercises in a full-screen view.
