Hello Chip,
The app is designed to be an extension of your PC logbook, fast data entry of new items, review of your reports/stats, and simple sync. It is not necesssarily a good idea to have your entire logbook on a device as they aren't nearly as powerful as a PC. It could lead to corruption, an extremely slow app, and some people that would use it as their sole logbook could end up losing it, losing everything, etc. I suggest taking a look at
this newsletter article where we discuss this in a poking pun at "Logbook Pro Watch Edition" warning people of this concept, and sure enough it happens all too often as we hear nightmares of other apps with total data loss such as happened with the iOS 5 upgrade, etc.
As devices become more powerful we will consider a full stand-alone logbook option with full sync of other logbooks such as PC, Web, etc. For now we are acting in your best interest by providing a solution that will be reliable, simple and fast to use, and effortless.
Thank you for your feedback. We hope the free apps we offer will help you keep your Logbook Pro PC edition logbook up-to-date with minimal effort.
