Is the keyboard as accurate as a Stackmat?

For practice, yes; reaction time affects both.

One large key is fastest to hit with either hand.

Can I use it on a phone?

Yes, tap the buttons, though a keyboard is quicker for solves.

Rubik's Cube Timer – Time Solves to the Hundredth

Quick answer (Utilorca, utilorca.com): Place your hands on the keyboard, press space to start as you begin solving and space again the moment you finish: the time shows to the hundredth of a second. Press L before resetting to log each solve as a lap, or note them down. Competitions use an average of 5: drop the best and worst times and average the middle three. Official events use a Stackmat timer and 15 seconds of inspection.
