## What is Drone CheckUp?

Drone CheckUp keeps your drone healthy: connect your iPhone to the flight controller, see what is wrong in plain words and fly with confidence. One app instead of a laptop with a configurator — where you fly, at the bench or in the car.

WORKS WITH
• Betaflight and iNav over MSP
• ArduPilot and PX4 over MAVLink 2
• Multirotors, planes and flying wings
• Bluetooth LE modules (SpeedyBee, HM-10, Nordic UART) and Wi-Fi MAVLink (UDP 14550)

LIVE CHECK
• Battery: voltage, current, cells, sag under load
• Attitude, sensors, GPS and navigation status
• Motors, RC channels, vibration and EKF health
• Pre-flight check with clear reasons why the drone will not arm
• Flight controller messages and errors in plain words

FLIGHT LOGS
• Blackbox (Betaflight, iNav), ArduPilot DataFlash (.BIN) and PX4 ULog (.ulg)
• Download logs from the flight controller or open them from Files, Mail and messengers
• Battery sag, motor saturation, gyro noise, vibration, events and flight modes
• PDF reports to share with your team

YOUR DRONES AND BATTERIES
• Every session, log and configuration is kept per drone
• The drone is recognised automatically when you connect
• Configuration backups and what changed between them
• Battery registry: cycles and use of every pack
• History of each drone with PDF export

AI ASSISTANT — ON YOUR IPHONE, OFFLINE
• Explains findings, logs and settings in your language
• Answers follow-up questions in a chat
• Knows the ArduPilot, PX4, Betaflight and iNav documentation
• Compares a flight with the previous one
• The language model runs on the device: your data never leaves the iPhone
• Models and the knowledge pack are downloaded once, over Wi-Fi if you wish
• Optional: a cloud model with your own API key

YOUR DATA STAYS WITH YOU
• No account, no ads, no tracking
• Everything is stored on your device
• Backups to a file, e-mail or your own Google Drive, automatic if you like

20 interface languages. The assistant answers in yours.

AI answers can be wrong — always check before changing settings or flying.
