GaitLab is the proprietary software method of programming the Freedom Innovations Quattro knee and Kinnex 2.0 microprocessor foot/ankle prosthetic components manufactured by Proteor USA. The application is used to connect to a Quattro knee or Kinnex foot, program it, troubleshoot it, and update firmware.

No other application on the VA App Store or the Apple App Store is capable of programming these components due to the proprietary nature of the software.
