Last updated: July 5, 2026

Plumb helps you notice slow posture drift by taking a consistent side-profile photo each day against an on-screen vertical guideline, then letting you compare today against a week or a month ago.

Purchases

Plumb Pro is a one-time, non-consumable purchase ($2.99, paid once, not a subscription) that unlocks unlimited photo history, multi-point comparison of 3–5 dates at once, and custom guideline colors/styles. The free app fully solves the core problem on its own, forever: daily photo capture with the guideline overlay, a 30-day visible timeline, two-photo comparison, streak tracking, and reminders.

Frequently asked questions

How do I restore my purchase?
Open the app, go to the Settings tab, and tap “Restore Purchases.” Make sure you are signed in with the same Apple ID you used to purchase.
Is Plumb Pro a subscription?
No. It is a single one-time purchase. You pay once and it is yours for good — nothing renews or recurs.
Is my data private?
Yes. Every photo you take stays on your device. Plumb has no network access, no account, and no third-party advertising or tracking SDKs. See our Privacy Policy.
Does Plumb detect my posture automatically?
No. Plumb is honest about what it does: the vertical and horizontal lines on the camera screen are a manual alignment aid so you stand the same way each time, and the plumb-line tool on saved photos is a draggable measurement you place yourself. There is no AI or machine-learning posture analysis in this app.
What happens to older photos on the free tier?
They are never deleted. The free tier just doesn't display check-ins older than 30 days in the Timeline. Everything reappears automatically the moment you unlock Plumb Pro.
How does the plumb-line measurement work?
Open any saved photo, then drag the two handles onto the points you want to compare (for example, ear and hip). Plumb shows you the angle that line makes from true vertical — a simple geometry calculation, not a diagnosis.
How do I delete all my photos?
Go to Settings → Delete All Photos. You'll be asked to confirm, since this permanently removes every check-in photo from your device.
