I Built a Web-Based Metronome That Lets You Edit Rhythms Freely (My Side Project Story)

As a developer, my escape after work is playing guitar and piano—it’s my therapy. But I had a huge frustration: my rhythm sucked. Even with a metronome, I’d miss beats, struggle with complex patterns, or find rigid "tick-tock" metronomes useless for syncopated rhythms.

So I build an online Customizable Metronome.

And I would like to ask for feedback
For musicians: Does this solve your rhythm struggles? What’s missing?
For indie hackers: How would you grow this? (SEO? Partnerships?)
