Would be nice if you could program sweet like designated frequency steps (like 20, 40, 80, 120, 160, 220, 440, 560, 800, 1000, 1400 etc) with eqch step twking the same (specified time). Then it could mimic Neutrik sound generator for measurements (if you happen to forget to bring it with you). The 1..x is nice on paper but not really that usefull.

Best frequency generator in the store. All the others were broken in some way. This one simply works and runs in the background with zero issues. Finally found a good one. Wish the volume was a bit more boosted, but it works.

fairly good app. it would be nice to have multiple frequencies. volume is very low in the sine wave. lastly an image if the wave form spectrum would be helpful. I'll give it another star if features can be added.
