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.

- 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.

This app does not run in background yet.

24KHz is only possible in phones with a 48KHz sample rate DAC. Some very expensive phones do not have such a DAC. This is a hardware limitation.

    Works perfectly (albeit with my speakers limitations). Would be nice to change the waveform? Thanks to the developer.

    When I change the orientation of my device from portrait mode to landscape mode or vice versa, the tones stop and I have to press Play again. Minor inconvenience but an inconvenience nonetheless. Please fix so that the tones keep playing when I change between portrait and landscape modes. Thanks.

    Here's an idea, how about using this app as a means to break up gallstones or other foreign bodies inside the stomach using attached speakers.

    I run this from 25 Hertz to 400 Hertz up and down and when I hear a rattle, I set that frequency so that I can go and find where the rattle is and fix it
