Measure your posture.
Then change it.

One side photo, analysed on your device, gives you a posture score and an 8-week corrective plan built around where your back actually hurts.

What Lumba does

Most posture advice is generic. Lumba starts by measuring you, then gives you a short routine you can actually keep up.

📐

A real measurement

One side photo. Your phone reads head position, shoulders, upper back and pelvis, and scores each out of 100.

🔒

Measured on your device

The measurement runs on your iPhone with Apple's Vision framework. The scan never sends your photo anywhere — only the optional before/after preview does, and only if you ask for it.

🎯

Built around your pain

Mark where it hurts on the body map and your plan targets those areas — neck, upper back, lower back or hips.

⏱️

Ten minutes a day

Short guided sessions with clear animations. No equipment needed, no gym, no brace.

📈

See the change

Rescan each week and compare side by side. Your score, your pain log and your streak in one place.

🧘

45+ exercises

Breathing, mobility, stretching and strength — each with a guided animation and clear form cues.

Eight weeks, three phases

Each phase builds on the one before it. The plan adapts to your activity level, flexibility and how much time you have.

WEEK 1–2

Calm

Ease symptoms and rebuild trust in movement. Breathing, gentle mobility, no load.

WEEK 3–5

Stabilize

Deep core and shoulder-blade control — the muscles that hold your posture when you stop thinking about it.

WEEK 6–8

Strengthen

Build endurance for daily load: sitting, lifting, carrying, driving.

The measurement stays on your phone

You decide if anything ever leaves it.

  • The posture measurement runs entirely on your iPhone with Apple's Vision framework. Taking a scan never sends your photo anywhere.
  • Your personalised reading is written by AI from the measured angles only — the numbers are sent, the photo is not.
  • The before/after preview is the one feature that sends a photo. It is optional, it asks first, and Google deletes the image after generating the preview.
  • Scans, pain logs, sessions and badges are stored on your device, encrypted while your phone is locked.
  • The only thing that reaches our own servers is an anonymous ID and your subscription status.
  • You can delete your scans at any time, and deleting the app removes everything with it.
Not a medical device. The posture score is an in-app indicator for tracking your own change over time — it is not a clinical measurement or a diagnosis. Lumba provides general exercise guidance, not medical advice. If you have severe or persistent pain, numbness, or a recent injury, please see a healthcare professional.
