CallMeBack

CallMeBack發送通知時，你不能打電話給你的數字。

How many times have you handwritten short messages to tell your friends to call you back when they are available? CallMeBack helps you send short callback messages with just two taps!

Once started, CallMeBack is completely HIDDEN and waits for your phone calls. After a call, a silent message will appear on the notification bar **for few seconds**. If a user is unavailable, then you can choose to quickly send him a message by tapping the app's icon in the notification: tap, confirm, done! :-)

- No data is consumed by CallMeBack after it is started, the energy consumption is practically zero!

- You can choose your preferred application to send the CallMeBack messages (SMS/WhatsApp*/Others).

- No any user information is sent to our servers! We care your privacy!

*Due to WhatsApp API limitation on Android version, it could require one additional click :-(

Detailed information about the permissions (for who concerns about the privacy):

- SEND_SMS, READ_SMS, WRITE_SMS

Required to send SMS by the app.

- RECEIVE_BOOT_COMPLETED

- INTERNET, ACCESS_NETWORK_STATE

Required for the little ad-banner, hoping that it will pay a coffee for the time spent by the developers! :-)
