Looks like a good little app but more importantly i'm glad to here that there is a naips app on the way. There are more android phones at work now than iphones so there will defiantly be a market for them and i'd happy to pay for it so that we keep getting development of Australian based aviation apps for android.
How is the naips app going? The copyright issues aren't being a problem are they? Any more development with a release date? It would be great if you released a public beta and we could help iron out any bugs before the release.
Once you get the naips app going have you thought about an reader for ERSA, AIP, DAPS, etc. Doesn't need to do anything fancy, just hold the latest versions and let you read it.
