User reviews

Finally found what I needed!

Accurate measurements, clean UI, and works in landscape and portrait mode. I’m very happy with the app! No issues. Thanks to the development team.

Works great for me!

I’ve tried a handful of programs, and so many of them are not very useful. This one is! It agrees with my HP spectrum analyser, and gives me accurate sweeps, white/pink noise so I can use my iPad as a generator for aligning equipment. I’ve spent more for apps that are nowhere near accurate. One says its doing 20khz and only puts out 10k. This will be the one I use.

Some suggestions

Your app is really good. I’d like to give you some suggestions to improve it: when I export the data in csv format, using time base of 1ms or lower, the data generated in the file is rounded to steps of 0.01ms each, resulting in repeated values for the “time” column. Please, Just allow some more figures to be shown.

Excellent all round

Easy to use and great feature set.

One slight hiccup - on startup, the generated tones/noise rapidly pulse instead of being continuous - this appears to resolve when the app is put into background then back (Installed on a 6s)
Update: - Thanks for response; originally found issue on ios11; also present with ios12.

Version 1.02 update: rapid pulsing of generated tones still present on my 6s under ios12.
