You can do this very easily by putting your data in Google spreadsheet and use https://my.infocaptor.com to track it. Here is how you would connect to google spreadsheet http://infocaptor.com/help/google_spreadsheet.htm

A while ago I built a similar tracking tool for my kid and then introduced to his friend's parents in our neighbourhood and they love the concept. We still use but haven't checked if his friend's parent still use.

Basically it is a google form, so we trained my son to go in and add the time and note down the activity http://www.infocaptor.com/help/kid_activity_dashboard.htm
