Herta captures every hit from your e-drums and shows you how you're playing. Get a full breakdown of each session - timing, dynamics, coordination, hand balance - and see how it all changes over time. Connect your e-drums over Bluetooth or USB. Hit record. Play. When you stop, Herta breaks down everything that happened. **SESSION BREAKDOWN** Every session gets a full analysis: per-pad hit counts, timing evenness scored Tight/OK/Loose, velocity distribution across ghost notes to accents, and coordination sync between limbs - hi-hat+kick, hi-hat+snare, cymbal+kick, and multi-limb clusters. **HAND BALANCE** On supported pads, Herta uses positional MIDI data to detect which hand played each hit. See per-hand velocity, consistency, and how your weak hand compares to your strong hand. **SONG DETECTION** Playing along to music? Herta detects song changes from Apple Music or Spotify, splits your recording into separate sessions per song - each with its own title, artwork, and analytics. **SESSION REPLAY** Play back any saved session and hear your hits through a built-in drum kit. Same dynamics, same phrasing, same timing. **PRACTICE HISTORY** Practice streaks, activity heatmap, session type breakdown, achievements across 40 milestones. Every session saved and synced across iPhone, iPad, and Mac via iCloud. Works for all levels - beginners learning first beats to advanced players refining technique. Rudiments, grooves, play-alongs, free play. --- Terms of Service: https://misfitscorp.com/terms-of-service Privacy Policy: https://misfitscorp.com/privacy-policy Questions or ideas?
