Stop watch app inventor
<p>I'm new user of App inventor. I need small stopwatch. Basic function:
 - set time ex. 25 min (if time=0;alarm=true)
 - start time
 - reset time (if you want reset time you will see the comfir box (yes or no)</p>

<p>Can anybody show me what block I must use to create it ?. Sorry for my English.</p>
