Both the TIMER and RTC modules are dedicated hardware timer modules, where the main difference is that the TIMER modules are clocked by the 16MHz peripheral clock, while the RTC timers are clocked by the 32.768kHz low power clock.

This makes the TIMER modules better for situations where you need fast, high accuracy timing, while the RTC timers are better when you want to keep the current consumption as low as possible.

The app_timer module is essentially a software based timing module that allows you to generate multiple timer callbacks at different intervals based on a single RTC timer, to work around the fact that you only have a limited set of TIMER and RTC modules available in the device.
