Stethoscope is evolving. Many doctors use traditional stethoscopes such as Littmann (not Littman). Some are trying Eko stethoscope, evolved but still hung over the neck. Stemoscope is very different. It is designed for everyone to listen to the heartbeat (heart beat) or breath sounds, or many other sounds of life, for STEM education, recreations and many other purposes.

It is a tubeless stethoscope. It is a wireless stethoscope. It is a Bluetooth stethoscope. It is a digital stethoscope. It is a mobile stethoscope. It is a smartphone stethoscope. It is a wearable stethoscope. It is likely the smallest stethoscope in the world. It is Stemoscope.

Sounds tell stories of life. They come from inside of a person, your pet or a plant and emanate outwards for us to discover and to appreciate.

Stemoscope detects sounds and transmits them wirelessly to your smart devices, phones or tablets, eliminating the cumbersome tube of the traditional stethoscope. A user can choose either a wired or wireless earphone to listen to these engaging sounds.

Stemoscope is the world's first wearable stethoscope. With the specially designed strap (might need to be ordered separately), you can easily wear it or carry it easily with you. It is so small that you can store it with your earphone in the same bag.

The stemoscope comes with an engaging App with many rich and useful features that are easy to use by anyone. You can save the sounds and the locations where the sound comes from. You can share the recorded sounds with others through emails. The App supports playback at half the normal speed so that it is easier for anyone to recognize the detailed sound characteristics. In the STEM mode, the stemoscope can even detect infrasounds that can‘t be heard by our bare ears. You can design your own sound filter or shift the sound pitch to hear sounds in a different and sometimes more insightful manner.

New Features (That Don't Work)

I was really excited to see that stemoscope has now provided the ability to livestream audio over the Internet to another user. I was about to try that today but immediately encountered an error when the other party attempted to make a contact with me through the app. It no longer connects and says i have an Internet connection problem. Restarting my iPhone 12 Pro Max doesn't solve the issue, and even uninstalling and reinstalling the app doesn't fix it.

It's awfully disappointing to have new features added to an app that are immediately broken in release. I'm okay with the app overall, but broken new features reduce my star rating from a 4 to a 3

Good concept. Audio quality is sub par

Took 3 months to come from China I had almost given up. Totally useless if you want to hear heart sounds amplified via the iPhone speakers. Have to use earphones or headphones. Even with that the clarity and volume that one can hear from a cheap $5 disposable stethoscope is much better. Only positive I can think of is because of Bluetooth one can be away from the patient and still hear something. Maybe helpful in covid situations. Lung/ airway sounds are more audible - would be interesting to know if it’s easier to discern pathological sounds.
Expensive toy with limited utility
In the meantime time try taping it to a tree or a piece of stone and hear some molecular motion!— Just kidding ! This is a basically a cheap Bluetooth microphone with bad Chinese electronics encased in a small disc. You can hear spontaneous crackles and a reverberations when the iPhone is close to the instrument. Needs better MOFSETS and a better designed circuitry to be of any practical use.

Decent app once you crack the code

When I first used the app I bounced off like you did/will. It’s confusing and finicky. Hopefully I can help if you don’t want to fiddle with it. I’ll mostly focus on the listen function:
-on heartbeat, the first listen option, is 20-200, this is the bell side of a traditional stethoscope. Just switch to the second one to get the diaphragm side. The UI makes sense once you know that.
- use the STEM option and put the 100-500 settings in, amplify it to 16x and pitch shift up to 1.5/2. That’s the best sound I’ve gotten, but I’m sure it could be dialed in.
— in the STEM menu, do the pitch shift and amplify first because the screen moves very easily and the slider hit boxes just aren’t right. Then type the numbers in you want.
-when you record a sound, make sure you take a picture first because I can’t seem to find a way to add one after you save it.
- the sound you recorded immediately disappears to the history menu.

Good luck! Hopefully some App love will make this 5 star worthy!
