Easy to use, and no issues so far


Where did the cast option go?
Trolik

I would like to cast over WiFi. Please add that option and you’re good


Works great for me

What I really like about this app, is that; 1. It doesn’t go quiet when you shut down your screen to save phone battery. 2. It saves your Hz from your previous session. Nice job.


Awesome app

I like how simple and effective this tone generator app is. I already purchased White Noise from this company and use it regularly to create a tranquil atmosphere at home or in the office. I’d love to have some additional features in this tone generator app. 1. Pulse - the user can have the tone pulse on and off automatically. Allow the user to select the length of “on” time and “off” time. 2. Audio Channel - the user can select which audio channel(s) the tone is sent through. Allow the user to select an option to alternate sending the tone to the left and right audio channels. Allow the user to set the switching speed to control how often the tone switches between the left and right audio channels. The audio channel options could be: - Stereo - Left Channel - Right Channel - Alternate Channels (with speed selection of “Alternate ____ times per minute”) Thanks for great apps!


Great tone app

One of the best free tone generators. The only suggestion I would make is to add the ability to manually enter the tone frequency.


Works as expected
Roman_Noble

Only thing I think it needs is to display the note of the sound played. A, A#, etc.


Good app

I like this app. It’s quick and easy. I do have some suggestions... The slider makes it a little difficult to hone in on a freq. In addition to the plus/minus buttons for incremental adjustment, maybe a 20 Hz jump button to get you close faster? Also, an octave jump button would be cool.


Great app

Just what I needed for 50 Hz tone to put new surrounds on a pair of speakers
