If you are using iCloud to keep the data in sync with multiple devices realize that you should backup your data but should not restore the backup unless iCloud data has been deleted or lost.
Do not take a Gun Log +P backup and try to save/restore it to Gun Log or Gun Log SPC, the iCloud data from Gun Log +P will cause a "save error" message to be displayed unless you are running 5.9 or higher.
These steps are the same for all of the Gun Log Apps.
You need a desktop computer and iTunes.
Step one. Connect iOS device to computer using the USB cable and open iTunes.
Step two. Select you iOS device in the left panel of iTunes. (The left panel is called the Sidebar. If you do not see the Sidebar go to the View menu and "Show Sidebar".)
Step three. Select "Apps". "Apps" is near the top middle.
Step four. Select "Gun Log +P". It is listed under "File Sharing" and below "File Sharing" is "Apps".
Step five. Select "Shooting_Buddy.sqlite" or "Shooting_Buddy_iCloud.sqlite".
Step six. Drag the sqlite file to your desktop or some similar location.
If you are using Gun Log SPC or Gun Log you can take the back up and transfer it to another device. Just hook up the device to your computer and in iTunes File Sharing just drag "Shooting_Buddy.sqlite" to the app's documents. It's just that simple.
