Thank you! ### 5/5 — Évaluation du logiciel. *2026-07-25* Très satisfait. ### 5/5 — Évaluation du logiciel. *2026-07-06* Très satisfait. ### 1/5 — Can not tell what the current levels are , why does it ask to record the level, when you are unsure *2026-06-27* Just record the level, do not have the consumer do it. They do not know where you are pulling the data from. What is current and what is past. ### 1/5 — Viel zu teuer *2026-06-16* Die Werte sind sehr fragwürdig (z.B. sehr hoher Stresslevel beim chillen auf dem Sofa) zudem die Premium-Funktion viel zu teuer ### 3/5 — Great *2026-05-19, version 1.4.2* Very helpful ### 3/5 — Good *2026-05-15* I like the app. It’s very comprehensive. But there’s no consistency to when it tracks the oxygen. Does it only work at night?? Why aren’t there regular readings during the day. I breathe all day long! I need to know why it’s not a consistent reading of oxygen all day long. ### 5/5 — Blood pressure *2026-05-05, version 1.4.2* 10% ### 5/5 — Chardinai *2026-05-02, version 1.4.2* Duvall1989 ## Frequently asked questions about Blood Oxygen App ### What does the Blood Oxygen App do?
