## What is 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. Check your iPhone dashboard to review your day

Small habit. Big difference.
