Xamarin Forms is great if you want to develop apps for different mobile platforms, but it is missing a critical functionality which every device with a touch screen needs. It cannot handle the various touch gestures. MR.Gestures adds Down, Up, Tapping, Tapped, DoupleTapped, LongPressing, LongPressed, Panning, Panned, Swiped, Pinching, Pinched, Rotating and Rotated events to each and every layout, cell and view and to the ContentPage. These events will be raised when the user performs the corresponding touch gesture on the element. In the EventArgs passed to the handlers you can see exactly what happened.
