LeDrum is a precision drum tuner for iPhone. It listens to each hit, detects the fundamental frequency in real time, and shows the exact pitch in Hz — so you can tune every lug to the same note and get a clean, consistent sound across your whole kit. Built for drummers, not guitarists. Drum hits are short, percussive, and full of overtones that trip up ordinary tuners. LeDrum locks onto the fundamental inside the noise of a real strike. HOW IT WORKS 1. Place your iPhone near the drum. 2. Choose the frequency range that fits the drum. 3. Tap near each lug and read the frequency. 4. Adjust each tension rod until every lug matches. THREE FREQUENCY RANGES - Low (65–120 Hz) — bass drum and floor toms - Broad (20–450 Hz) — full kit and rack toms - High (245–400 Hz) — snare WHY DRUMMERS USE LEDRUM - Real-time frequency readout in Hz, plus the nearest musical note - Live spectrum visualizer — see the strike, don't just hear it - Lug-to-lug tuning for even tension and clear tone - Works across the whole kit: kick, snare, toms - Clean, distraction-free display built to read at a glance FREE & PRO Start free with a daily tuning session.
