As this year's flying season goes slowly to an end in the northern hemisphere, and many of us will reach for the logged igc files, I can honestly recommend the Soaring Lab on-line app:

I have recently decided to go for the Pro version, which is not expensive (10 Euros or 12 USD/year). The map imagining is impressive, and all in all it is a good substitute for the IGC Flight Replay app which we used to like so much.
