Links to Apple health app. No extra bells and whistles. Not needed either. ### 5/5 — 3 years all good *2025-11-11, version 1.0.82* I used to wear both a fashion watch and a Fitbit for the last three year The Sequent has performed flawlessly and I have only had to charge it once every 6 months or so instead of twice a week with the Fitbit. ### 4/5 — Improving all the time *2025-11-01, version 1.0.82* Nice to see some updates finally coming. Stable and works well. ### 5/5 — Dr *2025-09-07* Good readings ### 5/5 — 3 years all good *2025-05-22, version 1.0.81* I used to wear both a fashion watch and a Fitbit for the last three year The Sequent has performed flawlessly and I have only had to charge it once every 6 months or so instead of twice a week with the Fitbit. ### 1/5 — Was great *2025-05-02, version 1.0.80* Was great but now the app starts like a fresh install asking to register or log in, and I can’t log in (login timeout) and the pass word reset doesn’t send a reset email. ### 5/5 — Getting better and better v2 *2025-03-22, version 1.0.80* The Sequent Oxyco app is a fantastic fitness tracker that offers a comprehensive range of features in a user-friendly package. With its customizable options, detailed insights, and easy-to-use interface, this app is a must-have for anyone looking to stay motivated and achieve their fitness goals. ### 5/5 — Still Works *2025-02-14* I have one of the original Elektron watches from the kickstarter (I think early 2021?), and it is still completely functional with the app. Pleasantly surprised. **Developer response:** Thank you so much. Keep posted on novelties coming! :-) ### 5/5 — Works just as it should *2024-09-18, version 1.0.74* Always works, never have any connection hassles with the watch, no complaints at all ## Frequently asked questions about Sequent OXYGO ### What does the Sequent OXYGO app do?
