Advanced electronic pilot logbook featuring: Fast flight entry, custom reports, secure backup features, social sharing and so much more. Use and synchronize across all your iOS devices for one simple price. *** User Feedback *** “This one’s a keeper. I’ve tried a bunch of logbook apps and they all had something wrong with them. This one is excellent. Easy to use, and the reporting system, where you create your own criteria to calculate times, and estimate when you’ll reach certain goals based on past performance, is far more intuitive to use than anything ****** has to offer. Also, the 3 tiered back-up system is excellent. Never gonna lose my data now…” "Us­ing the free tri­al, found it easy to use and full of func­tion­al­ity. Great job the de­velopers! The ease of con­nec­tion to aims has been great, and the pdf formats are su­perb. Will def­in­itely be buy­ing when the tri­al ex­pires." "Excellent Logbook ...
