You don’t need a bike computer anymore!!! Yes it’s so good, it even has Strava Live Segments! I’d rather pay annually for a good developed product and update my phone every two or three years than buy a bike computer for the same price of my phone and carry both with me on my rides. Yes battery life won’t be the same as a bike computer, but you can buy a power bank light and mount it under your phone and you’ll get more juice than you’ll ever need.
