Start-Stop Counter at App Inventor2
At my this post, i will continue to use App inventor 2. This is the first time of using app inventor2 since it is updated at 28 Feb.
My aim is making a downcounter that counts from a number that is entered from the screen. Then it starts downcounting when we press start button. If i press to stop, it freezes at that current number. After that we press to start again, it continues to count from the last number until it arrives to zero or stopping again.
