Drone CheckUp

Check your drone's flight controller right in the field

Connect your phone to a Betaflight, iNav, ArduPilot or PX4 flight controller, see what is wrong in plain words and fly with confidence.

Free to download. No account, no ads, no tracking.

  • Betaflight
  • iNav
  • ArduPilot
  • PX4
  • USB cable (OTG)
  • Bluetooth LE

Everything for the check before and after a flight

One app instead of a laptop with a configurator: on the field, at the bench or in the car.

Live check

  • Battery: voltage, current, cells, sag under load
  • Attitude, sensors, GPS and navigation
  • Motors, RC channels, vibration and EKF health

Why won't it arm?

  • Clear reasons the drone refuses to arm
  • Pre-flight checklist
  • Flight-controller messages in plain words

Flight logs

  • Betaflight and iNav Blackbox, ArduPilot DataFlash (.BIN), PX4 ULog (.ulg)
  • Download from the controller or open from mail and messengers
  • Battery sag, motor saturation, gyro noise, vibration

Your drones and batteries

  • The drone is recognised when you connect
  • Configuration backups and what changed between them
  • Battery registry: cycles and use of every pack

AI assistant, offline

  • Explains findings, logs and settings in your language
  • Searches ArduPilot, PX4, Betaflight and iNav docs and cites sources
  • Runs on your phone: data never leaves the device

Reports and backups

  • PDF reports to share with your team
  • Backups to a file, e-mail or your own Google Drive
  • Drone history with PDF export

How it works

The app is used on the ground: before take-off and after landing.

  1. Connect

    By USB cable, a Bluetooth LE module on the controller or Wi-Fi MAVLink.

  2. Check before the flight

    Battery, sensors, GPS, RC link, failsafe and arming blockers on one screen.

  3. Analyse after landing

    Download the flight log, see what happened and compare with the previous flight.
