It's about as good as it gets for an electronic logbook. It does everything including importing schedules from sabre, to exporting them to your calendar. Also calculates pay.

A few downsides though. Expensive subscription, Mac/iOS only. It uses icloud for syncing which is not very reliable (they need their own dedicated server for the price they charge). I also noticed on the newer versions, that I can't get all of the auto-fill fields to populate when I import my schedule (minor irritation). The old version worked a little better but doesn't support CFR 117 legalities.
