    Call-Timer can make your phone automatically hang up when your call reaches a configurable predefined time.

    Why it is needed? Many network carriers or telecom services offer free calls for first 5, 10, 20, xx minutes. If you don’t want to monitoring the elapsed time and manually hang-up the call while talking, then you can have this application do it for you.

    • DUAL SIM phones: In order to keep Call-Timer working well on dual SIM phones, you need to configure default SIM card for voice calls AND make calls from that default SIM card.


    + Auto hang up: user sets time limit once and the application will be in standby mode; whenever there is an outgoing call or incoming call (optionally), the application will be activated and begin to time the call.

    + Allow the timer to start counting time when other party answers call.

    + Periodic notifications: This is useful for people who are charged per minute.

    + Specific numbers: Allow you to specify individual phone numbers to apply limit of talk time to. You can add phone number to specific number list either by picking up contact from contacts list or by adding phone number prefixes, which are common beginning digits of the phone numbers that you want to add to the specific number list. Please note that when you choose to use “Specific numbers” feature, call-timer will not be activated (no auto hang up nor notifications) for phone numbers which do not belong to those numbers that have been added to specific number list.

    + Multi-call support. Please

    + Auto redial.

    + To be notified before hang-up

    + Exclude contacts from timer: If you don't want call timer to have effect on certain contacts or prefixes (for example, toll free numbers), you could do that though "Exclude numbers".
