APP timer V.S timer0, timer1, timer2

Dear, We are developing the nRF51822 for an application of BLE device. The timer is the key process in the application. Anyone kindly share the experience with me about the APP timer and normal timer(timer0/timer1/timer2). How do I know to use the timers and it would not impact the APP timer? Actually, I would like to generate a frequency during 30KHz ~ 40KHz. By the way, does the APP timer use a software timer based on timers (timer0 or timer1 or timer2 or RTC timer)? if so, what is the limit number?

APP timer is a software timer based on RTC1(32kHz), so it is independent from Timerx. On the other hand, you have to be aware that Timer0 is used by SoftDevice and it can not be used by user application…

On the other hand, you have to be aware that Timer0 is used by SoftDevice and it can not be used by user application (when softdevice is used). There is no hardware limit for instances of APP timer (user can specify it during initialization).
