There are a few apps that seem to have tackled the problem successfully, so I shall have to find out how to do this to make my app work well.
- Google's skymap is reasonably smooth, but noticeably laggy - could do a lot better 4/10
- Sun Path sylde is very jiggly indeed - 2/10
- 3D compass is quite responsive, but does tend to go a bit wild 5/10
- Steady compass takes a few moments to settle when first started but then is then very steady indeed and has very little lag - just a shame it's only doing it in 2D. 8/10
