Made to implement any poly-rhythm imaginable with any sounds user wants to use. Can't find a metronome with beat sounds you like? With this app, you can use any sound you can obtain local audio file with, or by recording it yourself. Type in rhythmical patterns and chords from sheet music to preview melody and use as accompaniment. Customize chord sounds with overtone configuration. Poly-rhythms are supported by playing several rhythms at the same time, all with customizable beats per measure and beat patterns. On the fly editing allows user to make any changes to the rhythms and hear them immediately. Easily customize volumes of each rhythm, even during playback to find the most comfortable setup. For players new to sight reading, a noise indication of next beat proximity may become a useful tool. Try your musical ideas with notation editing and export your creations as local wav files. Train by starting at lower tempo and having it seamlessly increase over time. Disappearing beats are supported. You can define constant beat dropout probability or have it increase over time. Sequential beat sounds are several sounds used for the same beat, which is useful for counting beats in a rhythm. All of the app's features are available for free, in-app purchases are used to increase certain limits for users who need them. ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Tip the Developer | $4.99 | one-time | | Tip the developer (tier 2) | $19.99 | one-time | | Full Unlock | $9.99 | one-time | | Unlock Beats per Bar | $1.99 | one-time | | Unlock Musical Notes | $1.99 | one-time | | Unlock Rhythms | $1.99 | one-time | | Unlock Bars | $1.99 | one-time | | Remove Set Limit | $0.99 | one-time | | Unlock Undo | $0.99 | one-time | | Remove Sound Limit | $1.99 | one-time | | Unlock Acceleration | $0.99 | one-time | ## Version history (last 5 releases) ### 1.6.4 — 2026-01-18 Added new visualization and many customization options, including rhythm color customization.
