Research shows Cobb Angle (x-ray) and vertebral rotation (scoliometer) are positively correlated. This app allows you to keep track of your scoliosis without an x-ray.

The Scoliometer by Spiral Spine allows users with scoliosis to measure their ribcage and vertebral rotation.

By using the app regularly, users can determine which therapies decrease their spinal rotation. 

This Scoliometer may also be used to determine whether scoliosis may be present.

How it Works:

The Scoliometer by Spiral Spine quantifies the rotational aspect of scoliosis and pinpoints the highest degree of rotation for each curve.

By measuring the spinal rotation before and after different exercise and spinal therapy sessions, users can determine if the body responded favorably to that session, and to what degree (through a decrease in rotation and a lower Scoliometer degree reading).


• Easy-to-use: three simple steps to get your reading
1. The person with scoliosis stands in front of the person holding the mobile device with the Scoliometer app.
2. The person with scoliosis slowly reaches their hands towards the floor, bending forward through the back.
3. The person with Scoliometer app pulled up on their mobile device puts their thumbs under either side of the phone while looking at the app. They rest their thumbs on either side of the spine and slide the phone down the person’s back in front of them while they roll down.
• Accurate: doctors can use it along with home users
• Informative: users can save their previous results on their own to show changes over time by saving a screen shot of the Scoliometer at the highest degree of curvature


Not sure if you have scoliosis? Get the app to find out if your spine has rotation. If your readings show that rotation is present, make an appointment with your doctor to confirm if scoliosis is present. Then, use the Scoliometer regularly to track your rotation.

No instruction or records keeping

It’s just a toggle that goes back and forth. The app has nothing to click to learn how to use it. It’s just a white background with a toggle moving but does not actually record what it sees. Basically like the level that I have in my toolbox expect on a screen. With no data collection while using it how is this useful? It should tell you how to use it and record data. Not just the numbers but the location of the numbers on the spine. Ugh what a waste. So disappointed.

East to use

Simple indicator that measures rib cage rotation. Helpful tool for Pilates pros!

I bought the app to use for my scoliosis but there is no record or holds to show the way your scoliosis shape. It’s wasting money.
