You’re 5 Minutes from Improving Your Shoulder Health

Whether you’re interested in your shoulder’s range of motion to avoid injury or recover from one, you’re holding the solution in the palm of your hand. Thanks to Reflex, your phone is the only tool you need to understand your current mobility. When you’re healthy, this app can help you recognize weak spots and avoid injury. When you’re in recovery, this app is your partner in monitoring recovery, assessing progress, and improving performance.

Using your phone’s camera, sophisticated AI technology recognizes your shoulder and guides you into position to capture measurements. In just five minutes, you can complete the exercises that help measure your range of motion. These exercises also pull double duty to help you rebuild strength in your shoulder muscles and ligaments.

You want to include static and dynamic stretches into your regimen to achieve optimum health. Reflex guides you through several exercises. Over time, the app tailors to your progress and suggests personalized stretches to improve your shoulder health.

You can make significant gains in your health at no cost with Reflex. You can download the app and set up a free account to complete two range of motion measurements per month and measure daily pain and sleep. If you appreciate the benefits of Reflex, you can upgrade to get unlimited measurements and custom features to enhance your experience.

No longer a good tool

This was a great app when it first came out. I gladly paid for it monthly to monitor my frozen shoulder progress. But as I just wasn’t seeing any improvement I decided to stop using the app. After ACR/MUA 11/2022 I decided to subscribe again to track my progress. Unfortunately I have not had the same positive experience. If I click on “history” I am just kicked off the app. None of my ROM progress pictures are recorded. The developer, who was very helpful with issues when using previously, after 3 weeks has not been able to fix any of the issues. They instructed me to contact Apple for a refund. They rejected my request. So a month of paying for this all was just wasted. I can no longer recommend as helpful. I’m not sure if the constant need to change and update caused the issues. But it is not the useful tool it was in the beginning 🤷🏻‍♀️

Just a waste of time. Confusing to use. Then “out of free measurements”
