★★★★★ The sounds transmitted are very very poor
★★★★★ Very basic without paid features, which are not great if you have spent becoming proficient in auscultation and ECG interpretation. Seems the latest updates also broke the app and the Eko device no longer connects.…

★★★★★ There is no way to speak to a human on the customer service line.
★★★★★ No option for it to stop asking.
★★★★★ I then reached out to Apple Pay and they would only refund a prorated amount stating they have no way to varify that I didn't get access to the subscription.

★★★★★ Have to pay for everything - would not recommend.
★★★★★ After a recent app update, the murmur detection feature was removed, and now it is locked behind a subscription paywall.
★★★★★ So I paid $400+ for this stethoscope, and now have to pay $112 a year to use the app functions they TOOK AWAY and are now making us pay for.

★★★★★ There's a bit of a learning curve for this old school nurse but worth it.

★★★★★ There is another nurse practitioner that I work with that has been wanting one but wasn't sure if it was worth it.

★★★★★ Very helpful In my medical practice!
2 of the 4 and 5 star reviews.
★★★★★ The device is beautiful and has a very professional look but if you can't use all the features it's kinda like having a beautiful dress that doesn't fit you.
★★★★★ Interface not very obvious when you just want to listen , not record, for instance abdominal sounds, femoral bruits etc

Latest reviews, United States App Store.
Dynamic auscultation with maneuvers like valsalva or stand to squat take time and the new short 15second limit is sometimes a disappointment, too short. Love the rest of the app and the great stethoscope
The new update limits recordings to 5-15 seconds vs. previously being able to adjust up to 60 seconds. Please can you resolve this issue as 5-15 seconds is not enough time to properly evaluate. Tysm
Ich finde es eine Frechheit, dass man Aufnahmen nur teilen kann, wenn man ein Abo für 130€ pro Jahr ausgibt!
Amazing! I received my stethoscope last year as a gift and unfortunately it broke. We contacted customer service about the problem and they immediately sent me a new stethoscope. We are so impressed! Thank you
Limits my stethoscope
This app is great for recording my findings as I learn how to recognise different heart sounds and rhythms. I find it very accurate when used with the Littmann Core stethoscope.
