Volume control bar too close to ‘select noise’ button.
I love Dark Noise, I use it every day to mask my tinnitus, especially at night.
However, the volume bar, the ‘select noise’ button and the iPhone’s home bar are all so closely positioned at the very bottom of the screen, such that every time I want to change the volume, either the app closes or I accidentally press the button to select another noise.
A minor downside, but a great chance to even further improve the beautiful app, in my opinion.
