Hello, I recently purchased the Phantom 2. I was thinking it might be fun to use an app to provide reminders for pre / post flight checklists and keep track of battery usage/ status. It might be nice to have a record of how many minutes each battery has been used and how many charges. Routine maintenance reminders would be great as well. It should also be able to record flight data such as time, distance, altitude, wind, temperature, etc... Does such an app exist? If not, what kind of data would be worth while to track? What else should the ideal flight tracking app do?
