Hi. I am looking for a timer that I can set for an amount of time, say 60 minutes but it would need to do 2 things, 1, not quit ringing until the stop button is pressed. That way, you don't just have a short reminder beep and if you miss it you miss it. I also need it to do this, 2, once the first 60 minutes or whatever amount of time has passed and you press the stop button it needs to automatically set another timer for that same amount of time with out having to manually set it up or pressing a start button every 60 minutes. Having it not need to be in the switcher would also be nice but not required. Having the ability to here the timers when the device is locked would also be nice but is not required. Is there such a thing? Thank you. .
