Jоkеr Drum app analytics for October 24

Jоkеr Drum is an offline-first workbench for acoustic drum kit setup and tuning. Every drum, head and piece of hardware gets its own full-bleed atlas plate you swipe through, and each piece carries its target note, lug-by-lug tension map, photos and voice notes. TUNE WITH NUMBERS, NOT GUESSWORK Tap a lug and the built-in Tuning Lab listens. On-device FFT and autocorrelation analysis show cents deviation from your chosen target note on a chrome LugDial arc that matches your drum's real lug spacing. A torque-pattern checklist walks you through the star pattern, cross-lug and fine pass so a full kit re-tune stays repeatable. KIT ATLAS Swipe one plate per piece — kick, snare, toms, side snare, hats, ride. Each plate holds shell size, head configuration, target note and last-tuned state, so you always know where a drum stands. TENSION MAP, PHOTOS AND VOICE NOTES The circular TensionMap shows every lug and its target-versus-measured pitch at a glance. A 3-slot photo strip documents the bearing edge, batter head and mounting position, and you can record voice texture notes describing how the drum actually sounds in the room. Photos and notes stay on-device and are pinned to the same piece record they describe. HEAD & DAMPENING LIBRARY 24 seeded head profiles (ply count, coated or clear, tuning range, attack, sustain, focus) and 14 dampening recipes (moon gel points, tape strip widths, internal felt, ported reso), filterable by your shell sizes and playing style. SETUP GEOMETRY PLANNER Drag shells, stands and cymbals onto an overhead kit grid with snapping, a pieces palette, full undo and redo, and layer lock. When the layout feels right, export a labelled setup sheet as an image to share with bandmates and drum techs. ERGONOMIC ADVISOR Enter height, inseam and playing style to get suggested throne height, snare tilt, tom angles and bass-drum beater contact point, rendered as a side-elevation diagram with live sliders and every angle written out in degrees. A/B TUNING COMPARE Record before and after takes of a single drum, study the overlaid spectrogram and envelope graphs, then play both back side by side with looping and gain-matched playback. 12 GENRE PRESETS Jazz, rock, fusion, gospel, funk, reggae, metal, brush, big-band, pop, worship and studio, each with cross-drum interval relationships, droop and rise ratios and reference tones played through the app. SAVED SETUPS AND REMINDERS Keep venue and preset variants of the kit — small club, festival, rehearsal — each with its geometry, target pitches and checklist. A widget shows today's setup, and scheduled reminders prompt head-replacement tuning reviews. Everything runs offline on your device. Your kit photos, measurements and voice notes stay local.
