FuckApp

First: FuckApp will NEVER share your information. NEVER.

FuckApp consist of two parts - a service and an app. The App (FackApp henceforth) is the interface to you as a user. The service is working in the background, silently protecting your personal life, or with continuous information to you as a user. It's up to you and two checkboxes.

Since it's FackService that does all the work you will probably not use FackApp very often.

FackApp will continuously learn your cycles and make better and better predictions
