Become a Supporter

$1.99 USD/mo

One price for full access. No lock-in.
Subscribe in-app.

Unlimited Conversions

Free accounts get 200 conversions a month. Supporters get no cap — convert as much as you want, whenever you want.

Your exports come out clean, with nothing but your music on screen. Ready to post anywhere.

New features land for supporters first, instead of arriving on a staggered rollout.

Questions and bug reports from supporters go to the front of the queue.

What happens to my .comet files after my subscription expires?

Only the converter is restricted. You can keep your .comet files and play them whenever.

Do you keep my MIDI data?

No. We do not collect MIDI data, and the .comet file that you create is stored locally on your device.

Which Operating Systems are supported?

CometMIDI is available in Windows. Mac and Linux coming soon.
