The frame rate number looks fine, yet the game stutters on my phone

Your AI reports a healthy number of frames per second, and still players feel hitches. A few long frames hide inside a good average. This entry reads a list of frame times and shows the stutters an average would never reveal.

Why this works

Players feel the slowest frames, not the typical ones. Looking at the worst few percent and at how many frames missed their time says what the player felt, where an average smooths it away.

When not to use it

Skip it for static puzzle screens that redraw only when something changes; time the response to a tap there.
