How to download SoundAssistant
If you wish to adjust volumes of ThinkUp and other apps like Spotify (so you can clearly hear your voice besides the background sound of binaurals beats) you can use a free app called "SoundAssistant" on Android to adjust the volume of each app on your phone. You can get it here.
Unfortunately, as of now, there's no alternatives for iPhone. I've looked for one long and hard and one of the reasons I switched phones was due to this. (It's an OS limitation with Apple). In this case, I'd just recommend recording your affirmations loudly and/or choosing a low volume binaural beats track.
