Star Walk – the app that helps users find over 200,000 stars, planets, constellations, satelites, and galaxies – has received a new update designed specifically for iOS 7. This makes tracking the night sky a faster and smoother experience, especially this November when people can use the app to find the ISON comet. Talk about a perfect time to be checking out this app! Users can even set reminders to make sure they don’t forget about any celestial event.
