IONIQ 5 OBD2 Monitor
GJSoft
IONIQ 5 OBD2 Monitor turns your phone into a live diagnostics dashboard for your Hyundai IONIQ 5. Connect a standard ELM327 Bluetooth OBD2 adapter and watch your car's high-voltage battery, charging, climate and more in real time, straight from the car's own computer. This is data the normal dashboard never shows you.
WHAT MAKES IT DIFFERENT
Most OBD2 apps look up your battery capacity in a table and print the same number for ever. This app measures it by watching how much energy sits behind each percent of charge over time, it works out your pack's real usable capacity and keeps it up to date as the battery ages. No model selection, no special charge cycle needed. Just drive.
WHAT YOU CAN SEE
Battery Status: real versus displayed state of charge, self-measuring usable capacity, pack voltage, current and live power
Vehicle Status: a live top-down picture of your car showing doors, hood, tailgate and lights, plus your decoded VIN and build details
Cell Voltages: every cell on a colour grid, with min, max and imbalance
Battery Temperatures: module sensors and the warm-to-cold spread
Charging: AC and DC power, charge-flap and cable status, and live time-to-80%
Diagnostics: state of health, cell imbalance (the best early warning of a failing cell), round-trip efficiency, high-voltage bus and insulation
12V system: auxiliary battery and DC-DC converter
Tyres: pressure and temperature for each wheel (TPMS)
Hypermiling: live efficiency and estimated range
Live Gauges: large, glanceable real-time dials
Vehicle details: speed, motor RPM, odometer and climate
Every value has a plain-language explanation. Tap any reading to learn what it means and what a healthy range looks like.
Settings:
The user can tune the app to its liking by configuring PSI/bar, C/F, km/miles, screen timeout and auto-connect.
PRIVATE BY DESIGN
The app has no ads, no trackers and no analytics. It does not even request permission to use the internet, so your car's data never leaves your phone.
FREE & PRO
Battery Status and Vehicle Status are free for ever, which is enough to check your battery's real health and your car's live state. An optional one-time Pro upgrade unlocks all the other screens. No subscription and no recurring fees.
REQUIREMENTS
A Hyundai IONIQ 5 (E-GMP platform)
An ELM327-compatible Bluetooth OBD2 adapter plugged into the car's OBD2 port.Without an adapter connected to the car, the app only shows the connection screen.
IMPORTANT
Do not operate the app while driving. Use it while parked, or have a passenger handle it.
