PIDOSO Smart Metronome Watch Wearable Digital Music Tool with Vibration Light Sound Tempo Beat Rhythm Adjustable Dial for Multiple Instruments Piano Guitar Drums Ukulele Bass Violin Saxophone

The app is not on Google Play apps. I tried downloading the app using the QR code in the instructions and my phone will not open or install the file. Using without software the device functions but the tactile part, basically the whole reason to buy this device, is terrible. It doesn't send a single pulse, instead it vibrates for a quarter second or so with every beat and the vibe is weak. It does not vibrate with subdivisions. At 180 bpm it is vibrating almost constantly from just the whole note. So the vibration is essentially useless - may as well just buy a regular metronome.

Perfect metronome!The design idea is very nice, using experience is very well, better than mechanical metronome a lot. I didn't want to hear sound, so I used the APP to turn off the sound and adjust the vibration intensity to the maximum. Drum mode is great, I used a few times, there are a lot of types to be chosen.Very nice metronome.

Kind of difficult to adjust the metronome tempos. Kept sticking and breaking the cheap rubber watch band. No app for Android. The sellers reached out and offered great help to fix the problem.

Does what it says on the tin but it can be very frustrating when pairing with the app. The vibration can be a bit stronger. While playing sometimes I won't feel it vibrate even on the highest setting as I'm moving my hands a lot. It is also much bulkier than one would presume looking at the pictures

This watch would not pair to the app at all. Also, the turn dial function was not acceptable. It was catching on itself and not turning. I was not able to test the actual functions of the watch since I could not pair it via Bluetooth as it was designed. Waste of time and money

The media could not be loaded.  Great product, my daughter used this metronome practice for a period of time, it really solved her practice problems, She does not have to disturb by the noise of mechanical metronome, and does not have to worry about the sound will disturb my feeling when practicing anymore.You could scanned their manual QR code to download and install the app.Excellent product, I will recommend it to others!

If you want to use anything beyond the most basic functions you need to download an app that is not on Google Play Store. The app is on their sketchy chinese site. Without the app you are stuck with vibration, lights, and beeping on with no way to adjust. Can not adjust time without app. The app requires full time access to your location, files, contacts, pictures, and media just to sync with Bluetooth. Most suspicious app I've seen for something so basic.

My android 11 phone cannot open the app file using their instructions. I decided to return it rather than settle with an inferior user experience. I did not try it without the app. Maybe if they get their act together and get an app that works and is available at the google store I will try it again.
