Every musician knows the feeling. You have a melody, a chord progression, a spark — but the room is empty. No drummer to lock in with. timml changes that. Just play. timml listens through your microphone, finds the tempo of your music within seconds, and joins in — with a groove that fits your style. No tapping. No setup. No menus. Just you and a rhythm that follows where you lead. WHAT TIMML DOES timml uses real-time audio analysis to detect your BPM and musical style, then drives a full drum kit that adapts as you play. When the energy builds, the groove fills out. When you pull back, it settles. When the moment calls for a fill, it lands on the one. THREE SKINS – ONE APP Choose between the warm Organic Mode, the precise Tech Mode, and the new Retro Digital Mode with 7-segment displays inspired by classic hardware drum machines. 12 DRUM STYLES Rock, Pop, Jazz, Blues, Funk, Metal, Hip-Hop, Latin, Bossa Nova, Country, EDM and Shuffle — each with style-appropriate patterns and fills. APPLE WATCH CONTROL Start and stop the groove, switch styles and generate new patterns — right from your wrist. Tap tempo directly on the Watch. Digital Crown adjusts BPM or swing. ABLETON LINK Sync timml with GarageBand, Ableton Live or any other Link-enabled app on the same network. Tempo and beat grid are shared automatically.

RECORDING Record your jam directly in the app — as lossless WAV or compressed M4A. Saved automatically to the Files app and shareable via AirDrop or Mail.
