Ratings and Reviews

Everything you could ask for and more.


This has everything I would need and more for a tone generator. It also has some interesting features I was not expecting but am thinking will be very useful. Very glad I opted for this one. Don't believe apple in app purchases label, the developers have made it all available for the initial purchase price which is amazingly little considering haw much functionality you get. Used to use "Tone Generator Pro" before they wrecked it with a complete overhaul. This APP is way better .



Quality App, I never write reviews but felt I had to for this, if you need a sig gen like I did dont bother with the others.

Ad City! Avoid


All was going well until the latest update. Then, the dreaded Ad disease kicked in. It was so bad that I am deleting it and moving to a competitor. Counter-intuitive, programmer! One star.
