Quiet volume
This has been an issue for awhile, as Ive had multiple iPhones. It’s quiet coming out of the iPhone speaker turned all the way up. Turning on amplification just adds a lot of distortion. When I connect to a Bluetooth speaker, I can have volume half way and it’s plenty loud (sometimes I don’t always have my bt speaker to be able to connect to it.) All other apps that play audio are way louder than this app at full volume thru iPhone speaker. Other than that, it’s been pretty great
