LugMap: Drum Tuning

About

LugMap: Drum Tuning is a paid, local-first tuning workspace for drummers, drum techs, studios, venues, and backline teams. Build a kit with drum sizes and lug counts. Enter measured pitch at each batter and resonant lug, set target frequencies, and see the full head as a positional balance map. LugMap calculates average pitch and spread, highlights outliers, and ranks a practical tighten-or-loosen adjustment order. Keep target references for every drum and export a named tuning report for the next session, room, or technician. Kits and readings persist on device and remain editable. No login is required. The app has no subscription, in-app purchase, ads, analytics, tracking, cloud sync, microphone access, automatic audio analysis, or developer-server upload. Measurements are entered manually and files leave the app only when you explicitly export them.
