MacDive for iOS has the ability to download from various devices that have Bluetooth LE support, or via the DiveNav DC Buddy (accessory sold separately). You can also copy supported file formats (LVD, UDDF, etc) via iTunes File Sharing and import them.

If you have a device supported by the DC Buddy that you don't see here, please email support@mac-dive.com and we'll see about getting it added for you.

No extra purchase is required to download via Bluetooth.
