The best of CHORDA
-
Say it, get a workout
Describe what you want and what hurts. CHORDA builds it from the library.
-
Change it in plain words
"5 rounds, plank last", by voice or text. You see every change first.
-
A video for every move
Nearly a thousand exercises, each with a short clip of how it's done.
-
Rest you can see
The screen flips its colors while you rest. The beeps get through silent mode.
-
A link anyone can run
No account needed to open it, and a public profile that goes with it.
-
Your AI agent can help
Claude, Codex and other agents build and share workouts, only with your OK.
One app, two ways to use it
Change it in a sentence
"Shorter rests, no jumps." You see what will change, and Undo is right there.
Train without the clock
A video and a countdown for every move. Beeps for work, rest and the last seconds.
See what you did
Every workout you start, your total for the week, and one tap to run it again.
Add your own exercises
Film it, frame the video, and CHORDA fills in the description and the tags.
Send it to your people
By name or email. Someone new gets a link that signs them up and opens it.
Put it on the web
Anyone can run it in the browser, and your public profile shows what you put out.
Hand the busywork to an agent
Claude, Codex and others find exercises and build workouts. They ask before deleting.
