11 of the 1 and 2 star reviews.
★★★★★ 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.…
★★★★★ Pay $500.00 for the Eko core 5000 then you'll need pay 100.00 per year to use it. I'm reselling mine and now use my Apple Watch instead. Hire a better marketing team that understands you'll get more money by letting…

★★★★★ 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.
5 of the 1 and 2 star reviews.
★★★★★ The company has lost its way.
★★★★★ It just records. Exam functions not available since the update. If this is not true I will adjust the review later.
★★★★★ I can't comment on the synchronization of the audio and the tracing, because I couldn't hear the audio.
4 of the 1 and 2 star reviews.
★★★★★ 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.
15 of the 4 and 5 star reviews.
★★★★★ I find it very accurate when used with the Littmann Core stethoscope.

★★★★★ Need watch app to allow easy connect and recording
★★★★★ This app is remarkably easy to use and has helped me gain greater insight into my patients' health!
★★★★★ Although the Eko's stethoscope head is quite bulky, this is a very easy to use electronic stethoscope.
6 of the 4 and 5 star reviews.
★★★★★ Very helpful In my medical practice!
★★★★★ This helps overcome the unilateral hearing loss.
★★★★★ It would also be helpful to have some way of identifying if the unit is on or off and the ability to “wake up” the unit after being idle for awhile.
5 of the 4 and 5 star reviews.
★★★★★ Love the instant feedback.
★★★★★ I could no longer hear bowel sounds and lung sounds and knew I needed a quick solution to avoid practicing a less than desired level of care with my patients.
★★★★★ The device works smooth along with the app.
5 of the 4 and 5 star reviews.
★★★★★ There's a bit of a learning curve for this old school nurse but worth it.
★★★★★ I downloaded the app and created an account only to find that I can't even use the stethoscope features without signing up for the two week free trial.
★★★★★ There is another nurse practitioner that I work with that has been wanting one but wasn't sure if it was worth it.

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.
