Add a PortaPack H1 to your HackRF One software-defined radio, and leave your laptop behind! The PortaPack H1 attaches to your HackRF and adds a touchscreen LCD, navigation controls, headphone jack, real-time clock, micro SD card slot, and custom aluminum case.
Just add a USB battery, and you're ready to explore radio spectrum wherever you are. The PortaPack firmware runs on the fast ARM processors in your HackRF. No computer is necessary (except for reprogramming firmware).
Here's a quick run-through of the current firmware features as of 2016 February 22:
