If you're cheap like me and thought paying $75 was enough for a logbook database you might still be using LogTen Pro, not the subscription product, LogTen Pro X. Of course Coradine hasn't updated the old LogTen Pro software, but it's still been working after many subsequent iOS updates. Has anyone who uses LogTen Pro updated to iOS 10 and does it still work? Does syncing between an iPhone and iPad still work? When LogTen Pro does stop working I'll probably switch to one of the free alternatives, but I do like the program and would like to keep using it as long as possible. If I don't hear any response I'll back up my flight times, try it myself, and post my experience here.
