A kick on every beat, then hats on the beats, then the eighths, then the sixteenths. Each step splits the beat into smaller pieces. Those pieces make a grid, and every note in your song sits somewhere on it.
When you played your hats in, the app wasn't recording sound. It was writing down each hit: when it happened, which drum, and how hard. That written-down version is called midi.
