### 3/5 — Free version doesn't do much

*2015-08-10, version 1.0.2*

This app is a pretty decent free app, but it's not much more than an audio player. I didn't see anything that would support the claim of matching your heart rate. And the picture and music selections are pretty limited.

My sense was that you could easily do the same thing with any audio player like the iOS Music app. Having said that, the audio samples the free version has are not bad. The sleep timer is a neat twist.

The frustrating thing was that the app offers the feature in the user interface, not grayed out. Then if you select the feature, such as the tempo, it prompts you to upgrade. 

The free version does give one a sense of what the app is all about.

### 4/5 — Relax

*2023-08-04, version 1.0.9*

L'application sonosync est une très bonne appli pour se détendre 
Mai si il y avait plus de musique ça serait 5 étoiles

### 4/5 — Very good music

*2021-10-11, version 1.0.9*

I really enjoy the calm music and the relaxing background images. I just have one request and that is to add a repeat track button so the user could repeat a song in a loop.

### 4/5 — Appli calme je ne m'en passerais plus pour m endormir

*2016-10-10, version 1.0.5*

Supere 👍

### 4/5 — Good App

*2015-08-17, version 1.0.2*

A good app to meditate and reflect with, I particularly like the water featured music and the ability to modify the tempo.  The photos are lovely and you get a much wider range with the update.  It would be nice to be able to control the length of time the app spends on each photo, but overall, enjoyable to use.

### 4/5 — Great for helping me sleep

*2015-07-23, version 1.0.1*

I found the music invaluable for helping me sleep in the late stages of pregnancy. My baby daughter fell asleep to it this morning too! I seem to enjoy the middle speed the most.

### 5/5 — Highly recommend

*2015-12-30, version 1.0.5*

I highly recommend this app, the music is great for relaxing or drifting off to sleep, and the images are lovely. There are 3 options to each tune offering a variation of tempo and sound depending on your mood and level of relaxation required. The sleep timer also works a treat. I recently contacted the creators and they were quick to respond. I originally had this music on CD so was thrilled to find it on an app. I have tried a lot of other ambient/relaxation apps but this has to be one of the best....!!
