Latest reviews, United States App Store.
It measures your heart rate but there is no read-out of oxygen level as promoted in information about the app online. The title said “pulse oximeter” and showed exactly the same logo. Maybe this developer is presenting a knockoff.
Accuracy is non-existent. It is 25-30 points different. iPhone is +- 25 beats. ie: iphone@~72 Finger machine @~ 97 Quiet and resting both times. Tried it several over 5/10 min.
Dachte zunächst, die App wäre super. Dann habe ich ein paar Tests gemacht und sagt bei meinem Tisch, dass dieser eine Herzfrequenz vom 80bpm hätte 😑. Naja die App ist nicht wirklich vertrauenswürdig!
App fängt sofort an zu messen und zeigt alles von 40-140 an stürzt dann nach 20 Sekunden ab. Konkurrenz ist einfacher und genauer.
Apple Search Ads this app ran in the last 90 days, from Apple's public ad repository.
Apple only publishes ads shown in the EU (EU Digital Services Act), with a 7 day delay. An app that advertises only outside the EU shows nothing here.
