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.

Notes
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.

Recent changes:
Version 1.83
+ Improved help in the freq. offset and phase features.
