Bad Elf Flex2.0.6 - App Store

This is the free companion utility app for the flexible, intuitive, and affordable Bad Elf Flex and Flex Mini GNSS receivers.

Designed for GIS and survey professionals, the Bad Elf Flex and Flex Mini connect to your iPhone or iPad via Bluetooth and provide high-accuracy location data to ANY and ALL field data collection apps in your workflow.

This app allows you to view the health of the Flex and Flex Mini hardware, change settings, and perform firmware updates. For the Bad Elf Flex, the app also supports purchasing and loading Flex Tokens into the hardware for enabling hardware-based features and correction sources. Several correction sources are supported including SBAS, RTK via NTRIP, and Atlas (L-band) satellite corrections.

NOTES:

* This app requires a Bad Elf Flex or Flex Mini to operate.

* Our "Bad Elf GPS" companion app supports our legacy mapping-grade receivers: Bad Elf GPS Pro, GPS Pro+, Surveyor, and GPS for Lightning dongle.

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