Need Hourly reminder/alarm for TP

[lefty11]

Hello, I am hoping someone can help me out without much of a bother. I need a basic app ( I am sure there is freeware , so not asking for warez) that has an adjustable hourly audible alert or hourly alarm . I did search and so far have not been able to find one that has a working file . You can pm me if you know of one or post a good freeware link. I realize this is rudimentary probably but I need one to use for a reminder every hour. Thank you PS, I ust need an app , not a new ROM or anything
