PlusAnchor Drum Tuner

DrumTuner is a frequency tool designed specifically for tuning acoustic drums. 30-day full trial, then a one-time purchase. Download free and redeem a 30-day trial in the app to use every feature. After the trial, a one-time lifetime purchase is required to continue using the app. 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. Included in the trial and lifetime purchase: • Real-time drumhead frequency readings • Batter-head, resonant-head, and target tuning • Tighten/loosen guidance and position matching • 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 completely optional. If you allow it, 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 turn sharing off or 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.
