This utility app allows owners of any Bad Elf GPS accessory to check the health of the Bad Elf hardware, view the GPS data being received, transfer and view trip logs, and install firmware updates.

Visit to learn more about the Bad Elf GPS, GPS Pro/Pro+, and the GNSS Surveyor accessories, which add a high performance GPS receiver to the iPod touch, iPhone, and iPad via the 30-pin dock connector, Lighting connector, or Bluetooth. The GPS data is usable by ALL location-based iOS applications in the App Store.

Note: Continued use of the GPS running in the background can dramatically decrease battery life.

Nice tool with great potential!

After a reboot of my iPhone 6S, Bad Elf Pro+ works perfectly. I would love to have integrated tools on the device like "GoBackPro", and be able to save POI's without saving a track. App works well, but crash sometimes. Just reboot the phone and it's OK.

Good in most ways

Lists trips in strange order? Not obvious how to change order to One's preference.
Headings not labeled in trip presentations.
Nonetheless it does a great job!

Great app !

Works well with my bad elf devices ( BE-2200 and 2300).
Latest version (v3) is even better than previous versions.
I'm quite satisfied.
