I recently purchased the White Noise and the White Noise Storm apps.
First of all: great work. Especially for the 'Storm' version.
But: I do have an issue. I put the sound at level 40 or 45. When receiving an e-mail, SMS, or other social media warning, the sound suddenly rises to 100 again. Quite annoying if you're trying to get some sleep.
How can we fix this?
