Metropoly - Polyrhythms

New in 1.3: the lane view. Build a polyrhythm, practice along, and export the loop as video. One purchase for iPhone, iPad and Mac.

Metropoly is a polyrhythmic metronome that turns polyrhythms into something you can see and feel. It helps you develop an intuition for complex rhythms by visualizing them in a way that makes their structure obvious at a glance.

BUY IT ONCE AND OWN IT

• No subscription.
• No ads.
• No sign-in.
• Every feature works offline.
• One purchase for iPhone, iPad and Mac.

BUILD A POLYRHYTHM

• Up to six rhythms, each with its own beat count, all lining back up every cycle.
• Every rhythm gets its own configurable color and sound, so the parts stay separable by eye and ear.
• If preferred, add a count-in of one full cycle of the first rhythm, so you know where the loop starts before it starts.

EXPORT THE LOOP AS VIDEO

• Render the current polyrhythm to a square video at 1080p or 4K.
• Choose a gray, black, white, or transparent background that drops straight into your edit.
• Loop it 1 to 64 times, with or without audio. Loops are frame and sample accurate, so they cut together seamlessly.
• Rendering carries on while you use another app, and tells you when it is finished.

PRESETS

• Save any configuration as a named preset and load it back instantly.
• The app reopens on the polyrhythm you were last working on.

THEMES

• Three light themes and three dark themes, following the system appearance or pinned to one.
• Separately configure the background color of the polygon view.

ABOUT THE DEVELOPER

Made by Thijmen Dam, an indie developer and musician building small, focused tools with care. Metropoly started as a way to practice polyrhythms, and grew into something I actually enjoy opening every day. Thanks for giving it a spin (literally!). It means a lot to me. If you have any feedback, do not hesitate to reach out.
