I can't speak at all for Logbook Pro or for the newer subscription-based Log 10 X (I currently still use the non-subscription-based Log10Pro). However, I can tell you that any software that is subscription-based must be considered carefully. I don't care how cheap it is per minute/hour/day, if you stop paying, you will no longer be able to input flights to your logbook. Personally, I think you'd be hard-pressed to find professional pilots who are willing to commit to having their logbook held hostage in this manner. But then again, I didn't see our current political landscape coming either. Oh, and if you do find a pilot who's happy paying the monthly/yearly fees, then I suspect they'll regret it eventually. My 2 cents.
