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!
This is a very technical app, but all the complexity is hidden from the user interface.

- Hey, 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.
