Stay away from these oxygen thieves… ### 1/5 — Maniek *2024-07-06, version 01.04.02.00* Scam. Application doesn’t work. ### 1/5 — It is not working dont order it *2024-05-05, version 01.04.02.00* It is not working at all ### 1/5 — Useless app *2024-03-31, version 01.04.02.00* Can’t register as app won’t recognise that you have read Privacy Policy ### 1/5 — Doesn’t work, no sync *2024-03-21, version 01.04.02.00* 1st sensor applied, and doesn’t pair with the app. It is recognised as already expired. Through facilitation, they recognised the issue and are gonna send another one, but it’s will take another 2 weeks to arrive, and let’s see if it works… They didn’t offer any compensation for the inconvenience. ### 1/5 — No funciona *2024-03-21* No se me sincroniza el aparato con la app. ### 1/5 — App does not work *2024-01-23, version 01.04.02.00* It is impossible to register, no matter which email address I put in it does not send a verification code. Without a verification code you cannot create an account. Without an account you cannot use the app. Very disappointing. ### 1/5 — Für viel Geld Ärger gekauft *2024-01-20* Konnte mich bei der App gar nicht erst registrieren. Das einzige was die App kann, ist mir sagen ich soll das User Agreement und die Privacy Policy lesen (ja, hab ich). Jetzt bin ich stolzer Besitzer eines Sensors mit dem ich nichts anfangen kann. ### 2/5 — Needs improvement *2026-03-27, version 01.07.02.00* Love the concept but needs big improvements to make it useful. You can only look back 24 hours and it’s so small you can barely read what time you were in Ketosis. Cannot look back or pull data historically. You also can’t log any food or exercise when you realise you had been in ketosis, so impossible to track when and why you raised at that time. Graph needs to be bigger, needs historical data, so not much use. The developers need to look at Vively for glucose. Much better experience. ## Most praised reviews (8 highest-rated) ### 5/5 — Life Changing *2025-02-04, version 01.05.00.00* This has finally allowed me to tune into what my body is doing with the foods I eat. I’m finally able to maintain ketosis and know how far I’m in it. Highly recommend this to take control of your metabolism and to see where you’re getting energy from! ### 4/5 — Very basic, good but could do more *2024-01-10, version 01.04.02.00* The set up journey is good, data connection seems solid and the dashboard view is great but there very little extra functionality beyond seeing your readings. Would be good to have more options for rolling averages and alerts for ketone level dips but the killer feature I’d like would be data export or sync to google sheets or something ### 3/5 — Good improvements but some bugs *2024-10-24, version 01.05.00.00* Great to have added alerts and being able to enter events such as eating or exercise to see how they affect ketones 👍🏻 But unfortunately the graph for 3 & 6 hour views now doesn’t draw the line, only dots and the line linking data from a previous sensor to current one goes all over the place… ### 3/5 — Basic *2024-05-25, version 01.04.02.00* Very basic would be great to add notes for food and exercise ### 3/5 — Great, but… *2024-01-07* I love the sensor, it helps me a lot with my keto diet. The app is very basic and I am waiting for improvements. Would like to know average fat burn the last 24 or 12 or 6 or 3 hours. And a linkage with my Oura ring! ### 2/5 — Optimisation potential *2024-04-04* Positiv: Connection to sensor is easy and real time monitoring works well. Stable ketosis is much more difficult to maintain, than I expected from former single point measurements. I really learn a lot. Room for optimisation: - make historic data available for more than 7 days. - since I use ketosis to fight migraine (successfully) the possibility to export the data would be very helpful. I‘d like to correlate it to meals, sleep, exercise etc. ### 2/5 — Viel zu wenig Funktionen *2024-02-23* Ich zähle mal auf was fehlt damit die App nur in die Nähe vo 4 Sterna kommen könnte 1. Alarmgrenzen 2. Apple Watch 3. Export der Werte 4. Zoomfunktion Bis dahin gibt es zwei Sterne. ### 2/5 — Verbesserungsfähig *2023-11-17* Ich habe keine Option gefunden, mehr als die letzten 24h anzuzeigen. Darüberhinaus wäre eine Kompatibilität mit Apple Health schön. Oder Alexa :) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
