Plumb: Posture Check

Plumb makes invisible posture drift visible over time. Most posture apps just nag you to sit up straight in the moment. Plumb does something different: it uses your phone camera to capture quick, private snapshots of your posture throughout the day, then shows you the trend — so you can actually see whether your posture is improving, holding steady, or slowly drifting worse, week over week. HOW IT WORKS - Today: a fast, guided check-in using your front camera - Timeline: a visual history of every check-in, so drift becomes obvious instead of invisible - Compare: place two check-ins side by side to see the real difference - Settings: reminders, units, and full control over your data PRIVACY FIRST Every photo is captured and stored only on your device. Nothing is uploaded, nothing is shared, nothing leaves your iPhone. You can delete your history at any time. PLUMB PRO — $2.99, ONE TIME Unlock unlimited history, side-by-side comparisons, and advanced trend charts with a single one-time purchase. No subscription. IMPORTANT Plumb is a self-awareness and habit tool, not a medical device. It does not diagnose, treat, or provide medical advice about posture, spine health, or any condition. If you have pain or a medical concern, talk to a healthcare professional.
