SitWit vs Poxture App
SitWit has a free version that tells you, through Notification Center, when you lean too far forward or back. Break reminders and statistics are sold as Premium. Poxture App works the other way round: a free hour every day, with every feature all day for your first 14 days, and one payment keeps it on all day. Every fact about SitWit below comes from SitWit's website or its Mac App Store listing.

Download Poxture App for MacChoose SitWit if
- You want posture alerts without paying. SitWit has a free version.
- You want to hear about leaning too far back as well as forward.
- You like a posture score, a colour in the menu bar, and statistics by hour and day on Premium.

- You'd rather pay once, $19, than pay for Premium every month or year.
What SitWit is
SitWit is a Mac app from No Problem Software. It "uses the webcam in your computer to analyze your sitting position". You calibrate it by showing it what good sitting looks like for you. Then it "will notify you as soon as you lean too far forward or back", through Notification Center, and calculates a posture score, and shows a colour in the menu bar. Its Premium page also lists a screen overlay that darkens the screen when you sit too close for a while.1,2,3,4
SitWit has been on the Mac App Store since April 2020. On 8 November 2026 its US listing showed six reviews from 2020 to 2024: four with 5 stars, one with 3 and one with 1, but too few ratings to show an overview. In February 2024, one reviewer praised how fast SitWit's developers sent a fix.4
Free, and what Premium adds
SitWit is free to download from the Mac App Store, and its site says the free version "will help you improve your posture when you sit badly". Premium adds break reminders and detailed statistics by hour, day and 7 days. SitWit's Premium page lists three subscriptions: $3.99 a month, $14.99 every 6 months and $29.99 a year. Its US App Store listing shows $3.99 a month, $19.99 for 6 months and $29.99 a year.2,3,4
In Poxture App, breaks aren't a separate plan. Sitting still too long is one of its eight checks: it nudges you after 40 minutes at your desk, by default, and standing up or stepping away starts the timer again. Poxture App is free to use: the first hour of each day is free for good, and for your first 14 days every feature works all day, and $19 once keeps everything on all day.
Which Mac you need
SitWit's site says it "works on every Mac that runs macOS 10.15 or later". Its App Store listing says it requires macOS 14.0 or later. Its last App Store update, version 4.3.2, is dated 9 April 2025.1,4
Poxture App runs on Apple Silicon Macs with macOS 15 or later.
Privacy
SitWit says "The images are processed in real time and are not stored anywhere", that you don't need an account, and that the app works offline. Its App Store privacy label lists identifiers, usage data and diagnostics, collected but not linked to you.1,2,4
Poxture App's camera images never leave your Mac. Poxture App sends usage counts with a random install number and, once a day, rounded posture scores with no install number, and supporters can turn both off in Settings. The privacy page lists every item, and how to check the camera yourself.
