Drum Tuner – PlusAnchor

DrumTuner is a frequency tool designed specifically for tuning acoustic drums. Free to tune. Pro is a one-time purchase. Basic tuning is free with no time limit. Try every Pro feature free for 30 days in the app; afterward you keep the free version, or unlock Pro permanently with a one-time purchase. No subscription and no automatic charge. Reinstalling does not restart the trial for the same App Store account. Previously purchased lifetime access remains valid. Place your iPhone beside the drum shell, make one clean strike near a tension rod, and DrumTuner analyzes the head's decay to show one final frequency. Compare positions around the hoop until the tension is even, then use a suggested starting point or set your own target frequency. Free: • Real-time drumhead frequency readings • Batter-head, resonant-head, and target tuning • Tighten/loosen guidance and position matching • Save up to 3 drums Pro (try fingerprints twice and recall three times for free, then a 30-day free trial or one-time purchase): • Drum fingerprints and original-hit recordings • Batter, resonant, and whole-drum coordinates • Recall checklists and drift history • Unlimited saved drums Sharing drum hits and diagnostics is on by default and you can turn it off at any time in Settings & Privacy. While it is on, short triggered clips and diagnostic information are sent encrypted to help reproduce issues and improve frequency detection. On-device tuning does not depend on sharing, and you can request deletion at any time. Actual frequency depends on drum size, heads, tension, strike position, room acoustics, and microphone distance. Suggested values are starting points, not rules.
