Timer starts at the same time as app launch. Time setting can be changed later! - The fastest timer app to launch - Just start this app when timer is needed. Countdown starts automatically! - You can always change the time setting - Even during countdown, you can freely change the time setting! The count is adjusted without affecting the countdown start time. - The default time can be set freely - You can freely set the default time which is automatically set at app launch. In the case of using on the fixed time setting, even tap is not required after app launch! Also it can be set to not start timer automatically. - Notification tells you even in the background - You do not need to keep the app open. Some notifications tell you the timer finish certainly. [The background of Quick Timer development] After filling hot water in the cup ramen, or after putting pasta in the pot ..., "How much time should I measure...?" I am often faced with such situation.... I think there should be app like "at first the timer launch, and settable later", and I made it. Actually this "settable later" function is more convenient than I had expected; there is no need to hurry to set time before timer launch, and also it can be corrected if there is any mistake, it works quite good. As such a timer, this have slightly unusual operation, however it will be soon got used to. If you like Quick Timer, please post a review. It helps my development greatly. Thank you! ■■■ About paid upgrade ■■■ All ads will be hidden in the upgraded version. ● About Auto-Renewing Subscription Subscription automatically renews unless auto-renewing is turned off at least 24-hours before the current period ends.
