Meteor Counter App for iOS
'Be a part of NASA meteor research with Meteor Counter!
When you go out to watch a meteor shower, bring your iPhone with you. With Meteor Counter, you can easily capture meteor observations with an innovative "piano key" interface. As you tap the keys, Meteor Counter records critical data for each meteor: time, magnitude, latitude, and longitude, along with optional verbal annotations.
Afterward, these data are automatically uploaded to NASA researchers for analysis.
Meteor Counter also provides a news feed and event calendar, which are updated by professional scientists to keep you informed of the latest meteor happenings and upcoming showers.
It's everything a meteor hound needs to get informed and get involved!'
