In this case you must store the information in a server , because the way I did it only works localy , comparing last data with new , eg. when you start a countdown send it to a server and when its finish send the information back to the user , and change the variables , the user must be connected on internet and you must check it too before everything , its a bit more complicated to do it , if I find a free and easy way to do it I let you know !
