It does not. You can get your pulse (which I already can get through my watch) and monitor your respiration. I signed up for a year because of the good reviews. I tried to cancel the subscription about 10 minutes later when I realized I could not get my oxygen. Still on the hook for a year. I guess there is no 10 minute trail period. Recommend you sign up for monthly until you determine if you like the app. ### 2/5 — Inaccurate and misleading *2026-07-18, version 2.64.0* The app is not clear that it’s just a tracker and the heart rate reading was wildly off compared to manually measuring ### 1/5 — Rubbish *2026-07-01, version 2.64.0* Doesn’t work at all and isn’t effective at all I placed the ‘monitor’ on different parts of my body and it gave the same reading each time I also placed it on the blanket and it did the same thing, also there is no free trial so you pay upfront and you don’t get your money back! Rubbish don’t bother! ### 1/5 — Not what I expected *2026-07-01, version 2.64.0* The only reason I shelled out 24.99 was because I needed to know my blood oxygen level ASAP ### 1/5 — Not a free app or free service *2026-06-30, version 2.63.1* I want to use the apple provided blood oxygen app but it's missing from my apple watch, I downloaded this cause it had a lot of reviews and was "free" I cannot even use it on my watch without paying a subscription. No thanks. I can buy a machine to do that from REI for cheaper than a year's sub. ### 1/5 — Inadequate info *2026-06-27, version 2.63.1* This product is a waste of $ if the info you’re interested in is a reading of O2 saturation. The only result I get is “normal” and I need specific percentages so I can track my condition. ### 1/5 — Toda appp muy caroo *2026-06-23, version 2.63.1* Toda app muy caroo ### 1/5 — Makes you pay for oxygen *2026-06-20, version 2.63.1* Won’t let you use your smart watch at all. Also the only way it checks your blood ox without purchase is by asking you how much you’re breathing. Do not waste your time if you’re looking for a free app. ### 3/5 — Stop *2026-06-14, version 2.63.1* Stop asking for reviews. ### 1/5 — Zero stars would be better *2026-06-12, version 2.63.1* This app does NOT track your blood oxygen levels. Paid for the pro version to sync it with my watch and still it just asks questions or wants you to manually add your PoX. What a waste of money ### 1/5 — Don’t buy *2026-06-10, version 2.63.1* This is a waste of money, your Apple Watch can already tell you your heart beat. I got it for the oxygen saturation, but it doesn’t actually tell you a %. It just asks questions. It says you have to have an Apple Watch 6, I have the newest Apple Watch, and when opening the app on your watch, it asks you for your %. ### 1/5 — waste of money *2026-06-09, version 2.63.1* save your money ## Most critical reviews (10 lowest-rated) ### 1/5 — Not free *2026-08-19, version 2.65.0* It requires a subscription. I immediately uninstalled. ### 1/5 — False Info in AppTitle *2026-08-11, version 2.64.0* You MUST read through the entire written description very carefully! THIS APP DOES NOT MEASURE YOUR BLOOD OXYGEN. You need an oximeter or Apple Watch that measures blood O2 levels. All this does is count pulse and you count respirations with a timer. Then it ESTIMATES BLOOD OXYGEN. Don’t spend the money if you are a patient on supplemental oxygen or you have a chronic respiratory problem like asthma!!! You still need your finger monitor for O2 levels! ### 1/5 — Развод *2026-08-06* Приложение сразу просит оплатить подписку для измерения кислорода, не давая даже один раз проверить, будет ли работать эта функция сейчас, когда Apple ее отключила в своем приложении. Я не готов платить за кота в мешке. ### 1/5 — SCAM *2026-07-24, version 2.64.0* It doesn’t actually check your blood oxygen. I just guesses or you check it yourself with a device and manually enter it. It does NOTHING. ### 1/5 — Arg stopped working After the Update of May/26 *2026-07-20, version 2.64.0* May 9/26 is the last reading this Paid for app gives. The only thing that seems to work is the “sleep report” the 1 thing I Don’t Want from this app. What is wrong with this app? ### 1/5 — Does not work …not accurate at all ..don’t waste your money *2026-07-19, version 2.64.0* Does not work ### 1/5 — Misleading *2026-07-18, version 2.64.0* Does not measure oxygen, it simply guesses based on general health questions. Wish I could get my money back! ### 1/5 — Completamente falso *2026-07-17, version 2.64.0* No se sincroniza con reloj, hay q hacerlo manual, no tiene sentido, quiero mi dinero de vuela, 0 estrellas👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻👎🏻 ### 1/5 — Daily 02 not updated *2026-07-08, version 2.64.0* I wish I hadn’t bought the year subscription which I have now cancelled. This app does not keep the daily 02 updated sometimes not until late in the day. I’ve found other .99 apps that are much better!!!! ### 1/5 — Renewed but it’s not working *2026-07-02, version 2.64.0* Please help me get this to work ## Most praised reviews (10 highest-rated) ### 5/5 — Just what the Doctor Ordered *2026-07-12, version 2.64.0* I have several extremely rare autoimmune diseases and Dysautonomia is a constant this app provides me a journal of sorts to keep my data all in one place. ### 5/5 — Easy to use *2026-07-09, version 2.64.0* Just place your finger on the camera lens and you get a heart rate reading. ### 5/5 — App assistance *2026-07-07, version 2.64.0* Thank you for the quick response and solution to my Blood Oxygen App. It is working daily now. ### 5/5 — Health and fitness *2026-07-03, version 2.64.0* Very good health monitoring app for daily routine of heart and oxygen monitoring. ### 5/5 — When it’s important ! *2026-07-01, version 2.63.1* The amount of oxygen in the blood can tell you medical information about your heart and lungs. ### 5/5 — Just *2026-07-01, version 2.63.1* J ### 5/5 — It’s great *2026-06-24, version 2.63.1* Thanks it’s helping a lot ### 5/5 — Handy *2026-06-11, version 2.63.1* Great to have this information ### 5/5 — THANKSage13lotttosgames *2026-06-08, version 2.63.1* LOVEBIBLELIGHTS ### 5/5 — Great app so far! *2026-06-06, version 2.63.1* So far it’s been great --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
