Screwy Volume

Screwy volume when using the iPhone side buttons. Jumps up and down by 6 or more, also displays wrong volume level (sometimes even shows “muted” when not). NEEDS to be increased and decreased by 1. Slider works fine but I very much dislike sliders especially when they’re that small. Other than that nice app with lots of features. Using on iPhone 12 Pro and iPad Pro 9.7, same issue on both. Please fix! Will change to 5⭐️ when this issue is fixed.

Update: I wasn’t aware the volume button issue was an Apple limitation. Hats off to the developers for being so attentive to the end users. Outstanding app! Money well spent.

Developer Response ,

The increment/decrement of 6 via the volume buttons is implemented that way by Apple. I can’t change this. Since the volume range is 0-100, this is intentional I guess because it would require too many button presses for volume changes. Best, -tom

Outstanding App!

The details and options of controlling sound waves is more than you could ask for in a iOS app! It’s pure mathematics in your hand... and ears! Although I have many technical/scientific uses for it, I like to set up a deep-bass, oscillation, multiphase-waveform as I lay on a couch with a subwoofer underneath - a fully customizable back massage... the ultimate no-contact TENS device! Thank you to the developer for keeping it up all these years!

528hz, 432hz healing audio & binaural beats

This app makes it easy to play 528hz, 432hz, Solfeggio tones, white noise and other custom audio frequencies for healing and any other audio production, meditation or enjoyment purpose.

Any creative audio professional should get ahold of this app, especially if you want to use non-standard tunings. I use it to match tones, tune songs, audio files and instruments by ear, play true binaural beats, match frequencies on my modular Synthesizer and more. It’s my go-to reference for 432hz, 528hz and Solfeggio tones for my music.

Thanks for making this app!
