The KISS Principle (Keep It Simple Stupid):
My goal was to design and program a simple app that does the job, and not full off options that would introduce bugs and turn the app difficult to learn an use. Sometimes, less is more!

Under the wood
This is a very technical app, it has hundreds of hours of work, but all the complexity is hidden from the user interface.

Permissions
- This app does not read all your contacts!
- In-app purchases: this permission allow users that want to support the future development and maintenance of this app to upgrade to PRO VERSION, paying a small fee, and without installing a new separate version. This process is the new trend in phone apps. This is a one time purchase only.

Limitations
This app does not run in background yet.

Recently changed in this version

Version 1.78
+ Add master volume control (feature asked by many users).
+ Add fine volume control. Android volume control is very coarse, with only 16 levels. The 1 level may be to high for users that use this app to meditate or with tinnitus. Now you can fine tune the lowest volume setting.

= Correct issue when the user is pro and there is no internet connection to check the licence.

This update in only possible thanks to the users that are supporting the development of this tool.

    Produced a weird jittery tone as well as the one I needed. No use at all.

    It could be annoying! But fun at the same time or at least know what the heck I am doing.

    I did a science experiment about hearing and frequencies, and this is the app I used. Thank you for your app. Fun Fact! Did you know that if there is an infrasonic sound wave at 8-16 Hz, at 177 dB, it could control your breathing? At 189 dB, I can stop your breathing with that noise.

    Easy to use. Does what it is supposed to. Purest tones of any app that I've tried and the new "exponential fade-in fade-out" means I can hear throughout the range of frequencies.
