Hi everyone, here is my experience: after having tried different electronic logbooks I have recently discovered FLIGHT LogBook (https://play.google.com/store/apps/details?id=com.mattia.flightlogbook) which I can say so far is the best for quality/price I've tried. Apparently it's a young project made by a group of pilots with passion for IT. No subscription needed, only paid 12 euros at first purchase and they claim there will never be any monthly or yearly fee to pay. I have to say it’s definitely worth the price, it features tons of different statistics, dropbox backups and excel exports. Also generates a Jeppesen copy of your logbook to print and let you monitor your weekly/monthly activity. Interface it’s really easy and simple to use, and they also seem to respond to emails quite fast each time you need support. Absolutely satisfied.
