Smart Metronome & Tuner +17.8 - App Store

The "Three Essentials" of music practice, unified on one screen.
Metronome, Tuner, and Recorder. We have integrated the three indispensable tools for every musician into one elegant and intuitive interface. No more switching between apps-stay fully focused on your music.

- Professional Precision: 1/44,100 sec.
Do you have doubts about the accuracy of digital metronomes? Smart Metronome controls timing and sound playback via hardware, not just software. This guarantees an exact pulse, independent of CPU load, with a precision of 1/44,100th of a second. Technically, it is the same as listening to a recorded CD.

- Ultra-Realistic Visual Pendulum
We have recreated the physical movement of a mechanical metronome. The sound triggers exactly as the pendulum passes through the center, allowing you to "see" the tempo as well as hear it for intuitive synchronization.

- Exclusive Features to Maximize Your Efficiency

*** 3-in-1 Interface: Everything at Once**
Tune your instrument while you play. Record your session instantly and analyze rhythmic errors visually thanks to the "Metronome Guide" overlaid on the audio waveform.

*** Repeat Mode: Master Difficult Passages**
Ideal for tackling tricky sections. Start at a slow tempo and increase the speed automatically. Set the start and goal tempos and the number of repetitions to build your scales and arpeggios with total focus.

*** Program Mode: For Complex Pieces**
Freely program changes in time signature, tempo, and bar counts. Perfect for contemporary music or pieces with shifting rhythms (rit. / accel.). Includes rehearsal marks on screen so you always know where you are in the score.

*** Continuous Timer & LOG: Practice Management**
Manage your routines with the continuous timer. Every minute of your practice is saved in the LOG, allowing you to visualize your progress and consistency over time.
