StandLock vs Stretchly: Which macOS Break Reminder Is Right for You?
Last updated:
Looking for a Stretchly alternative for Mac? StandLock is a free, MIT-licensed break reminder built natively for macOS 13 and later. It has three break levels: Gentle shows an overlay you can skip at once, Firm delays the skip and asks you to type a phrase, and Strict can block keyboard and mouse input for the whole break. Strict needs the Accessibility and Input Monitoring permissions and has a hold-to-escape shortcut: hold Control, Option and Command for about ten seconds.
Stretchly is also free and open source, runs on macOS, Windows and Linux, and has a strict mode of its own: a fullscreen break window with no close button. That hides the way out but does not block input at the system level, so the two strict modes are not the same thing. If you need one app on more than one operating system, choose Stretchly. If you only use a Mac and want breaks that are harder to skip, and that wait for your calendar and calls, StandLock is the better fit.

StandLock
StandLock is a free, MIT-licensed menu bar app for macOS 13 and later, built natively in Swift, so there is no bundled browser engine and memory use stays low. It is made for people who dismiss ordinary break reminders: each schedule gets its own break level, and Strict can block keyboard and mouse input for the break once the Accessibility and Input Monitoring permissions are granted. Until then a Strict schedule runs as Firm. It reads your calendar and checks camera and microphone use to defer breaks during meetings.

Stretchly
Stretchly is an open-source (BSD-2-Clause) break reminder built on Electron. It runs on macOS (Monterey 12+), Windows, and Linux, so you can use the same app on every computer you own. Breaks come in two sizes: micro-breaks and full breaks, each with configurable intervals and durations.
In strict mode, Stretchly shows a fullscreen break window with no close button. That hides the way out; it does not block keyboard and mouse at the system level the way StandLock's Strict mode does, so the two are not equivalent. It pauses when Do Not Disturb is active, and resets its timer when you have been idle. You can customize break ideas, themes, sounds, and keyboard shortcuts. The tradeoff for cross-platform support is higher memory usage: Electron bundles a Chromium instance, so Stretchly typically uses 150-300 MB of RAM versus under 50 MB for a native app.
Stretchly does not read your calendar or detect active calls. If you are in a meeting, you need to either enable Do Not Disturb or manually pause the app.
Key Differences
- Native vs Electron: StandLock runs natively on macOS with low memory usage. Stretchly uses Electron, which costs more RAM but enables cross-platform support.
- Meeting awareness: StandLock reads your calendar and detects camera/mic activity. Stretchly only pauses during Do Not Disturb, which you must enable yourself.
- Discipline levels: StandLock has three (Gentle, Firm, Strict) with different enforcement behaviors. Stretchly has two modes: standard and strict, where strict removes the close button but leaves input free.
- Platform reach: Stretchly works on macOS, Windows, and Linux. StandLock is macOS only.
- Customization: Stretchly supports custom themes, sounds, and break idea text. StandLock focuses on scheduling and enforcement over visual customization.
Which Should You Choose?
Choose StandLock if you use macOS exclusively and want your break reminders to automatically pause during meetings. The native runtime keeps memory low, and three discipline levels give you fine control over how forcefully breaks are enforced.
Choose Stretchly if you work across macOS, Windows, and Linux and want a single break tool on all of them. Stretchly also has better theme and sound customization. The higher memory footprint is the cost of cross-platform compatibility.
StandLock is not the right pick if you need Windows or Linux, or if custom themes, sounds and break-idea text matter to you. Stretchly covers both.
