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.
