Know your Prysm Score—in 15 seconds.
Prysm iO tracks carotenoid levels in your skin with a simple fingertip scan—so you can understand the impact of your nutrition and build better wellness habits over time.

FAQs
Quick answers to the most common questions.
Why is my Prysm Score fluctuating?
Some natural variation is expected—even under controlled conditions. Larger changes are usually caused by inconsistent finger placement/pressure, movement, a dirty lens/finger, or needing recalibration.
How often should I calibrate?
For best performance, recalibrate about every two weeks (the app may notify you).
Will my scan history be saved?
When connected, the app can sync scans to a secure cloud system. Your device can also store scans done offline—sync periodically to upload and save them.
I can't connect my device—what should I do?
Confirm the device is charged and Bluetooth is enabled on your phone and for the app. If needed, you can factory reset by plugging in the charger and holding the power button for 10 seconds until LEDs flash three times.
