Everyone is a gangster (Rajdhani, Shatabdi, Tejas) until the real Gangsta (Vande Bharat) walks in 😂 - Mushfique Khalid

u can try speedview and Uliysse speedometer ( freely downloadable from Google Play )

i have gps enabled handset

try these both. but remember mobiles have A-GPS that is GPS is dependant on internet connection so if you lose your internet connectivity then u cant measure speed. Also u get only approximate speed and many times they are wrong for eg i used to 100+ kmph on EMU when the MPS in 95 kmph . I still prefer the milestone and watch method for speed

the apps i mentioned are android apps. I dont have idea of apps for OS like iOS, Windows OS or for Blackberry os

thanks
