Blood pressure and sugar reading stay the same everyday . Went to doctor found out all wrong pressure was way higher and all numbers . Waste of money ### 1/5 — Misleading offer *2026-06-24, version 1.0.5* It leads you to believe you can try it for .99 p but actually does not expire for one week so I’ll be paying almost £7 for an app that is next to useless as it does not monitor blood pressure as is suggested. ### 1/5 — Scam!!! *2026-06-20, version 1.0.5* This App is a scam DO NOT spend your money on it, it does absolutely nothing….cheap thieves ### 1/5 — Engano?? *2026-06-14* Pq vcs falam que é grátis, quando é preciso pagar? ### 1/5 — Its not free *2026-06-13, version 1.0.5* Download is free but to use the app cost money. ### 1/5 — Misleading *2026-06-11, version 1.0.5* Advertisement showed it somehow measures blood sugar? How? Manually entering it doesn’t mean anything given you would need bloodwork done prior to using the app. I knew it was BS but gave it a try anyway. The pulse is completely off from my fitness band, there is no help screen, the app doesn’t remember age and a total waste of space on phone. Don’t bother downloading ### 1/5 — Beware- false advertising *2026-06-10, version 1.0.5* It does not measure blood sugar as promised and the blood pressure readings are off by more than 30 points as I measured right after the doctor did! ### 1/5 — Free??? Not!! *2026-06-06, version 1.0.5* The very first page asks you to sign up and asks for your billing information ### 1/5 — App is Free- Using it Isn’t *2026-06-02, version 1.0.5* Don’t advertise as a FREE app with in app purchases when the first thing a person sees upon opening your app is a page wanting money! Don’t waste peoples’ time and patience if you want to succeed. That little stunt has soured me on your company and I am deleting the app as soon as I send this message. ### 1/5 — Waste of time *2026-05-30, version 1.0.5* Wish all these apps would stop lying!!…… It’s not FREE only the first couple of days are free then as per usual you have to sign a subscription. So it’s not free. You get nothing for free not in this life. ### 1/5 — It’s not free *2026-05-20, version 1.0.5* Why say it’s free when it isn’t. ### 1/5 — A wast of time *2026-05-20, version 1.0.5* Not worth it 99p for the week then £9.99p a week that is just outrageous it’s just another way to scam money out of people that’s what £120 a year no thanks I’ve deleted the app now. ### 2/5 — Venden la aplicación como verificador del azúcar en sangre y no es así *2026-05-16, version 1.0.5* Confunden al usuario porque con esta aplicación no se puede comprobar fehacientemente el contenido de azúcar en sangre ### 1/5 — Fake app *2026-05-13, version 1.0.5* No known FDA approved apps can Check blood sugar with a phone app. Its a scam ### 1/5 — Don’t even bother *2026-05-11, version 1.0.5* Your ads are total scams, it states categorically that it quickly measures blood sugar without needles and is free neither of which is true, it only measures your heart rate. ## Most critical reviews (10 lowest-rated) ### 1/5 — Useless *2026-08-19, version 1.0.7* I held my finger over the camera, as indicated. Nothing! It registered one reading and it was metric. What a waste ### 1/5 — False Information *2026-08-19, version 1.0.7* The ad says you can check your blood sugar, but the reality is, it’s only a logging tool. Useless to me. ### 1/5 — Disappointed *2026-08-19, version 1.0.7* I never could figure out how this application worked to make my life easier ### 1/5 — Totally false advertising *2026-08-16, version 1.0.7* The ads for this app blatantly claim features it doesn't (and can't) have. A phone app alone cannot measure blood pressure or glucose. ### 1/5 — Did not work *2026-08-13, version 1.0.7* Down loaded paid, nothing. ### 1/5 — Memec3 *2026-08-05, version 1.0.7* The blood pressure reading has been faulty for me. Does not even come close to Mr blood pressure cuff readings when taken moments apart. ### 1/5 — Unhappy *2026-07-23, version 1.0.6* The app doesn’t work. A scam and complete waste o f money. The app won’t even let me complete my email and comments. Had to go to the App Store to communicate ### 1/5 — Doesn’t work *2026-07-18, version 1.0.6* Kept my finger still over the camera for over 3 minutes and nothing happened. No reading. ### 1/5 — False advertising *2026-07-05, version 1.0.5* Your advert clearly states that your phone can measure blood glucose, clearly this is a lie, seems that it’s about time someone starts legal proceedings against you for false and misleading advertising as you could very easily make someone ill with your claims ### 1/5 — Not free! *2026-06-30, version 1.0.5* The ad said it was free. Very first thing that popped up was a choice of plans, requiring a decision/payment. Some apps give you free access to some things and not to others. This one charges you right off the bat. Nothing is free. The ad is not only deceptive, it’s a flat out lie! ## Most praised reviews (10 highest-rated) ### 5/5 — Hígado Graso *2026-08-20, version 1.0.8* Como hago para conocer si mi hígado está graso?? ### 5/5 — checking heart health *2026-08-19, version 1.0.7* feeling good about results ### 5/5 — TRUST *2026-07-14, version 1.0.6* How can you trust an app that can’t even spell right on its address ### 5/5 — Bueno *2026-06-15, version 1.0.5* Bueno ### 5/5 — 好评 *2026-06-08, version 1.0.5* 好用 ### 5/5 — review *2026-03-03, version 1.0.5* AWESOME ### 5/5 — Exelente *2026-03-02, version 1.0.5* Bien ### 5/5 — Vitals *2026-02-05, version 1.0.5* The fact that all my vitals was accurate and I loved how the apps weight lost tips based off your personal BMI ### 5/5 — أربيل *2026-02-01, version 1.0.5* جيد جدا ### 5/5 — Good insight *2025-12-24, version 1.0.5* Let me know things I can do to improve my health internally --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
