Excellent but a bit overpriced.
Id rate this 5 stars, but I paid $10 for it which seems a bit overpriced. The main thing I need is notification of K indices >=5 to make sure my quadcopter doesnt have GPS problems and this seems to be the only app that does it. The app is well designed but needs an update for the iPhone 6+ screen ratio. It would also be nice to see a universal version with iPad ui support.
