I switched my testing order so the phone goes first and the desktop goes second, on every RAXXO tool without exception
A desktop-first habit hid layout and tap-target problems for months because the biggest screen forgives the most mistakes
Testing on a phone first forces the same discipline as writing a short sentence instead of a long one, cut what does not fit
The rule survives even for tools built for a keyboard and a terminal, because the landing page and the first impression are still mobile
The Habit I Had Backwards
