How to manually transfer a safe to and from the iOS app?

You can either use email or iTunes.

To use email, you need to email yourself the safe file. If sending it from an iOS device, unlock the safe and tap the share button to the bottom. Then, select "Email Safe". Otherwise, when receiving the email on the iOS mail app, tap on it and then select the option to open it with pwSafe.

To use iTunes, connect your device to your computer using the USB cable and open iTunes. Then, click on your device, on the "Apps" section on the left pane under "File Sharing" and then on pwSafe on the left list. Finally, use the document list to drag and drop. Please note that only unsynced documents are available on iTunes File Sharing.
