HA.

Laugh once. Get a score across five acoustic axes and one precise note for your next take. Practice privately, then post to your Room only if you choose.

Your laugh is a motor skill. HA. measures it, scores it out of 100, and tells you the one thing to work on next.

TAKE A LAUGH Make one short recording. HA. scores attack, cadence, separation, voicing, and commitment, then turns the weakest axis into a precise coaching note.

BUILD THE SKILL Practice in about a minute, compare each rep with your day-one baseline, and watch your score, streak, and mastery move over time. Ear training and a reference laugh help you hear the target before you try it.

PRIVATE BY DEFAULT Recording and scoring happen on your iPhone. Nothing is posted unless you choose to post it. There are no ads, subscriptions, analytics, or cross-app tracking.

THE OPTIONAL ROOM If you choose to join the 13+ Room, you can post a short reel to people you connect with by invitation. You control what you post. Reels can be reported, accounts can be blocked, and you can delete a reel or your complete Room account in the app.

The playful net-worth ladder is entertainment. HA. is vocal training and entertainment—not medical care, therapy, financial advice, or a medical device.

The whole app is free.
