I tried a lot of different relaxation apps before finding this one and I found exactly what I was looking for! I can choose whatever sound is soothing for me or that may be how Im feeling at that time and there are so many options! The only downside to having so many options is that it isnt as well organized as it could be within the app. I really enjoy all the places I can save sound mixes! This is one of the best relaxation apps out there and the best in terms of customization.
