Visible

Visible (Visible Health Inc.) develops activity- and symptom-tracking technology designed for energy-limiting chronic illnesses rather than fitness. Its stated focus is Long Covid, ME/CFS, fibromyalgia, POTS and EDS, and its central use case is "pacing" — balancing activity and rest to reduce the risk of crashes or post-exertional malaise (PEM). The product has two parts: the Visible Band 2.0, a screenless, waterproof armband for continuous heart-rate and activity tracking that the company states is manufactured by Polar and offers up to five days of battery life, and a paid membership giving access to the Visible app.

The app provides PacePoints for budgeting daily energy, real-time over-exertion notifications, activity tagging to show how specific activities affect the user, and tracking of heart-rate variability (HRV), symptoms and medication. Additional features include a Stability score (including from overnight measurements), morning/evening/monthly check-ins, HRV biofeedback breathing exercises, trends and exportable health reports that can be shared with clinicians, and an Early Access Hub for new features. A separate free research app, which requires no membership, lets users measure biometrics such as HRV and resting heart rate using a phone camera, log symptoms and exertion, and opt into app-based research studies; users can also opt in to share data with researchers.

The company maintains a scientific advisory board of researchers and clinicians in complex chronic illness, including Michael A. Osborne (University of Oxford), David Putrino (Mount Sinai), Todd Davenport (Workwell Foundation), Suzanne Vernon (Bateman Horne Center), David Strain (Action for ME) and Resia Pretorius (Stellenbosch University).

Founding story

Co-founder Harry Leeming describes developing ongoing symptoms for three years after a mild infection at age 29 and encountering a lack of recognition, support and tools for his condition, which led to building a patient-powered platform intended to help him and others with similar illnesses.

Business model

Consumer subscription hardware-plus-software model: members receive the Visible Band 2.0 wearable and pay for a Visible membership that unlocks the app's all-day pacing insights; the Google Play listing indicates in-app purchases and a free tier alongside monthly and annual fees. A separate free research app is offered with no membership required.

Paid membership/subscription for the app and wearable band, with in-app purchases; the company states the membership is HSA/FSA eligible.

Traction

The website states over 100,000 members use the wearable platform; the Google Play listing cites over 250,000 people using Visible for pacing, 100,000+ downloads and a 5.0 rating from about 4,810 reviews. The company reports that 86% of members feel more in control of their illness and 91% are better able to manage their energy.

Latest developments

Recent app updates include a colour change from red to orange for over-budget/exertion states, faster syncing between the band and phone, and general fixes; the Google Play listing shows an update dated 2026-08-10. The company also promotes HSA/FSA eligibility and an Early Access Hub for testing new features.
