THOUSANDS OF 5-STAR REVIEWS “Visible has been LIFE-CHANGING. I had fibromyalgia before COVID and thought I did well at pacing, but this has helped me on a whole new level.” – Roma “This is the first app in the 33 years since I have been diagnosed with this condition that shows me the data my doctor and I need. Fitness apps don't work well because they are not geared for people with POTS and PEM. This is the very first app that warns me when I have to SLOW DOWN and the monthly reports help my doctors get a better picture of how I'm doing.” – Lesli “Visible has been life changing making an invisible illness visible. It has been credibly validating to have concrete evidence to show to others about what is going on behind the scenes." – Eleanor Visible is not intended to provide medical services such as diagnosis, cure, mitigation, prevention, or treatment of any disease or medical condition.
