Slouch no more!
"I've had the tendency to lean forward on my keyboard since I started working. This often results in assorted back pain and troubles. After trying various seating arrangements, Posture Reminder AI has helped me keep a more comfortable / healthier position!. ”
5 out of 5 stars
Great Posture Monitoring app!
"This is the most interesting/creative AI app that I have seen and super helpful, especially now we are all working from home. ”
Setup
Choose a camera that can see your face and shoulders, then show the app your natural upright posture and your usual slouch. Sitting and standing each use their own calibration. A new camera may need recalibration before monitoring resumes.
Step 1
Sit the way you want to work: relaxed, upright, and natural. Keep the camera angle you will use during the day.
Step 2
Show the position you usually drift into, so reminders fire for the pattern you actually want to change.

The full-featured trial lasts one hour from your first app launch. After it ends, choose a monthly or annual Mac App Store subscription to continue monitoring, or restore an existing purchase.
You can still open Settings and the tutorial after the trial ends.
Click the app's Dock icon to reopen its window. You can also choose Show Window from the menu bar while Energy Saver is active.
Energy Saver keeps posture monitoring running in the background. The menu bar also provides Settings and Recalibrate actions.
Yes. Choose Sitting or Standing on the main window. Each mode uses its own upright and slouched calibration, so calibrate Standing before monitoring at a standing desk.
You can switch modes without restarting. If the selected mode needs calibration, the app prompts you before monitoring.
No. Camera selection, Posture alerts, reminder frequency, and Launch at Login changes apply without restarting Posture Reminder AI. Camera and notification permissions also refresh when you return from macOS System Settings.
If you select a camera without a matching posture calibration, the app pauses monitoring until you recalibrate with that camera.
Download Posture Reminder AI from the Mac App Store and try posture monitoring for one hour without a credit card.
After the trial, monitoring requires a subscription. The US Mac App Store lists monthly and annual plans at $9.99 and $99.99. Prices and plan details can vary by region; check your local App Store before subscribing. Apple manages billing and cancellation.
Posture Reminder AI requires macOS Tahoe (26.0) or later and a built-in camera, external webcam, or supported iPhone camera through Continuity Camera.
Allow camera access for posture monitoring. Allow notifications if you want posture alerts. Keep your face and shoulders in view while you calibrate and work.
Recalibrate when you change your camera angle or desk setup, or when reminders no longer match your posture. Sitting and standing modes each need their own upright and slouched reference positions.
You can switch cameras in Settings without restarting. If the selected camera does not match the saved calibration for the current mode, monitoring pauses until you recalibrate with that camera.
Yes. An external monitor works as long as a camera can see your face and shoulders. Choose your Mac camera, an external webcam, or a supported iPhone camera through Continuity Camera in Settings > General > Camera.
The camera changes without restarting the app. If the new camera has not been calibrated for your current posture mode, recalibrate before starting monitoring again.
For camera placement ideas, see our ergonomic accessories guide.
Open Settings > Notifications, turn on Posture alerts, and choose Remind every. You can set the minimum time between reminders from 10 seconds to 60 minutes.
The new setting takes effect without restarting the app. It controls how often an alert can appear while slouching is detected; it does not send reminders on a fixed timer when your posture is upright.
If the app opens but the camera view is blank, open System Settings > Privacy & Security > Camera and allow Posture Reminder AI. Return to the app; it refreshes camera permission without a restart.
If the camera is disconnected or being used by another app, reconnect it or choose another camera in Settings > General > Camera. Recalibrate if the new camera needs a posture baseline. If the app itself will not open, contact support.
macOS Focus can silence Posture Reminder AI notifications unless the app is allowed in that Focus profile.
Once allowed, posture reminders can appear even while Focus is on.
Yes. Posture Reminder AI is designed so your posture data stays on your Mac.
The camera is used only for live posture detection, similar to a coach watching your posture in real time without keeping a recording.
You can enable Launch at Login inside the app.
After that, Posture Reminder AI opens automatically in the background whenever you sign in to your Mac.
There is no iPhone app right now, but you can use your iPhone as the camera for Posture Reminder AI through Apple's Continuity Camera on Mac.
You need a Mac running the latest macOS Tahoe release and an iPhone that supports Continuity Camera and is updated to a current version of iOS.
For the best results, mount the iPhone at eye level on a stable stand. See our recommended iPhone stands.
The camera is how Posture Reminder AI tells the difference between your upright posture and the slump you want it to catch.
Without a camera view, the app has no signal to measure your posture.
Posture Reminder AI uses on-device computer vision and a personalized model built from the setup examples you record.
During setup, you capture your natural upright posture and the slump you want the app to catch.
After that, the app monitors posture in real time on your Mac and sends a reminder when it detects that same drift.
For a technical overview, read how Posture Reminder AI works.
Yes. Posture Reminder AI is currently available only on Mac.
There is no Windows, iPhone, or Android version today.
The app is built specifically for macOS and uses Apple's on-device machine learning frameworks to analyze posture privately on your Mac. If you want support for another platform, contact us.
