About Uncross
Uncross helps you become aware of and break the habit of crossing your legs while sitting — a common cause of poor posture and discomfort. Wear your Apple Watch. Start a session. Uncross quietly monitors your movement and sends gentle reminders asking if you're crossing your legs. Confirm or deny with a tap. Over time, you'll see your patterns clearly and naturally sit better. FEATURES • Apple Watch detection — motion-aware session tracking right from your wrist • Gentle nudges — randomized reminders so you stay aware without feeling nagged • Daily dashboard — sitting time, crossing estimates, and a confirmation rate score • Streak tracking — build momentum with consecutive improvement days • Weekly & monthly trends — charts that show your progress over time • Quiet hours — set a schedule so reminders only appear when you want them • Watch complication — your streak count always visible on your watch face • CSV export — take your data anywhere • Privacy first — everything stays on your device, nothing is ever uploaded HOW IT WORKS 1. Open the Watch app and start a sitting session 2. Uncross monitors your movement and pings you at random intervals 3. Tap to confirm or deny whether you're crossing your legs 4.
