We rebuilt BeltTune from the ground up. Smarter Detection Engine — Completely reworked audio analysis delivers dramatically more accurate frequency readings, even in noisy garages and workshops. Harmonic filtering now tells the difference between your belt's true pitch and its overtones, so you get the right number every time. All-New Design — A cleaner, more intuitive interface makes tuning faster and easier to read at a glance. Spend less time squinting at numbers and more time getting your belt right.
