The fundmental thing about a strobe tuner is that it is a continuous display of the difference between a target frequency and an observed frequency. The display could be neon lamps and a rotating disc, or ring of LEDs, or even a computer screen, but it is the difference frequency that is displayed directly, and not a moving average computation (which is absolutely, positively, necessarily significantly delayed).
What makes a strobe tuner interesting, though, compared to a needle, is that it shows not only how the fundamental overtone (of whatever note is being played) tunes, but also all the harmonic overtones above it. The Peterson software-based tuners show several overtones in the simulated display, but they are not independent like they are on a real strobe tuner.
