Still sitting since 9 am?
Chairtax takes over your screen. Do a few reps in front of the camera and it's yours again.
Sitting all day is bad for you
Hours in a chair raise your risk of heart disease, weight gain and high insulin.1
- Energy
- Every break gets you up and moving.
- Strength
- Squats and chair stands work the biggest muscles in your legs.
- Heart
- Jumping jacks and high knees raise your heart rate.
- Blood sugar
- Chair stands every 30 minutes cut the rise in insulin after lunch.2
How a break goes

Heads up
Thirty seconds before a break, a notice gives the movement and the target.

Get moving
The screen is covered on every display. Stand where the camera can see your head and hips, and do the reps.
-

Back to work
Success! You can continue with your work.
Six movements the camera counts

A card over your work. You can dismiss it, and that ends your streak.

Questions
Does the camera picture go anywhere?
No. Chairtax only uses the camera to count your reps, on your Mac. The picture is never saved, uploaded or shown to anyone, and the app's one connection is the licence check. The break screen shows a stick figure by default; your camera picture appears there only if you turn it on. The privacy policy has the details.
What happens if a break comes up during a video call?
Breaks wait while another app is using the camera or microphone. Before each break Chairtax checks, and if one is in use, the break waits five minutes and checks again.
Can I get my screen back in an emergency?
Yes, at every rank. Press Emergency override on the break screen, and the screen comes back after 60 seconds. If you finish the reps first, it comes back then. Every break ends on its own after 15 minutes.
What do I need to run it?
A Mac with macOS 14 or later and a camera, built in or connected. For the camera movements, stand back far enough that the camera sees your head and hips.
