    Poorly designed app, took 10+s to get to the main screen before you can tap on a number to do any operations. Please improve this app to make it open immediately without the lengthy loading process. Sometimes you just don't get the call after it crashed in the background. Message notification is delayed as well even i have turned off all the battery optimization for this app on my galaxy note 10. Suggested to add "Default number" so that i can jump into the main screen of the dialer app.

    It is not work as what it said. The app always stop without any notification, and also all sms are not push to notification. Haven been blame by all my customers as the number all is untouched-able, and sms not pushing is a very big issue. The company only replied very standard and basic reply. Tried to reinstall the app or that is my cell service provider's problem. NOT GOOD AT ALL.

    Not the best. Slow to start up. Can't delete certain contacts. It crashes every time I press edit. Annoying. Otherwise OK.
