Yes, it will occupy RAM. When the app timer is declared, ~4 bytes of RAM is reserved for the timer.

uint32_t app_timer_create(app_timer_id_t * p_timer_id, app_timer_mode_t mode, app_timer_timeout_handler_t timeout_handler)

we use the function to init timers.it can set "APP_TIMER_MODE_SINGLE_SHOT" or "APP_TIMER_MODE_REPEATED"

you say that only limited by the available RAM..i want to know if i set it to APP_TIMER_MODE_SINGLE_SHOT,when i not use or use use up it , it will also occupy the RAM??

Hi,

There is no fixed max limit. You are only limited by the available RAM. So you should be able to create a couple of hundred timers.
