Getting a good reading
Prop your iPhone on its side on the floor, about 2 m away, with your whole body in view from hips to feet. For the middle split, face the phone; for a front split, turn side-on. At your deepest point, hold still for a second. A level phone gives the most accurate angle.
A hold won't count
The timer only runs while the camera sees your hips and feet and you're still. Check that your feet are in the frame and the room is well lit. You can also choose “Count without the camera” from the ⋯ menu.
Subscriptions
Manage or cancel in Settings → [your name] → Subscriptions on your iPhone, or from Settings → Manage subscription in the app. To get a purchase back on a new phone, use “Restore purchases”. For refunds, see Apple's refund page.
Safety
Never force a stretch, and stop if it hurts. One Eighty isn't medical advice.
