Is there any specific plugin for speedometer in Ionic3 ?
Do you mean the Accelerometer?
The various native plugins work with device specific stuff like hardware. If this isn’t what you are looking for you can browse through the other options.
Im looking like this: https://play.google.com/store/apps/details?id=com.guruinfomedia.gps.speedometer&hl=en_IN
I really can’t write the app for you, but you’d start here with the GPS device, present in the phone:
You’d be determining how far the phone as traveled over a set amount of time and then doing the math to covert it to MPH or KPH.
Thanks i will check with geolocation plugin
