Used for years, great app
Have used the free version of this app for years as a sound maker for my kids. Use it on walks in the stroller, in the car, in their rooms, and on trips around the world. Been an absolute life saver blocking noise and helping them (and me!) sleep. Prob one of my top 3 apps on my phone.
