Your charger is real wattage, iOS App
See your real charging wattage — no dongle
What it does
iOS has never shown charging wattage. You plug in a cable and get a lightning bolt — no idea if it's 5W or 20W. WattCheck estimates real-time wattage by tracking battery % rise against your iPhone's known capacity. No dongle, no extra hardware. Plug in → watch the speedometer go from Bicycle to Jet. ⚡ Compare cables side by side 📊 Session history 🎯 Fully native SwiftUI 🆓 Free with ads · $1.99 one-time, no subscription ever
