The best movement reminder is the one you'll actually leave installed. That means it has to (1) reach you reliably, (2) respect your attention instead of weaponizing it, (3) work on every screen you live on, (4) keep the basic feature free, (5) not collect data you don't want it to, and (6) be made by someone whose interests align with yours. Most apps in this space get two or three. A good one gets all six.
There are a surprising number of movement reminder apps out there now. Some are very good. Some are very loud. Some are very expensive. We made one of them and obviously we think ours is the best, but the most useful thing we can give you is the way to evaluate any of them yourself, including ours.
Below are the six dimensions we'd weigh, in roughly the order they tend to matter. Run any candidate through them and you'll know what to install before the trial expires.
does the reminder actually reach you?
This is the only criterion that's binary. If the reminder doesn't land when you're heads-down in something, the app has failed at its single job. Test it by setting it for ten minutes, opening a focus app, leaving your phone face down, and seeing whether anything pulls you out at the ten-minute mark.
The strong versions of this category use background-reliable notifications, lock-screen alarms, and (on the newest iPhones) full-screen alarms that ring through silent mode. The weak versions are just a foreground timer in a tab. Both can be marketed as "movement reminders." Only one of them works when you forget.
Phone on silent, app closed, you're absorbed in something. Did anything reach you?
does it respect your attention?
This is the criterion that disqualifies the most apps in the category. Many movement reminders are built to maximize how often you open them, not how often you move. That looks like punishing streaks (lose your 47-day chain because of one bad Tuesday), guilt-trippy red dashboards, leaderboards, "you've sat for X hours today" shame counters, and notification copy that reads like a personal trainer with anger issues.
The whole point of a movement reminder is to protect your attention from the chair. An app that takes back attention with one hand while pretending to give it with the other has the wrong business model.
Read its notification copy. Does it sound like a friend or like a guilt machine?
does it work on every screen you live on?
Your sitting happens across a fleet of devices. A laptop in the morning. A phone in afternoon meetings. A bigger screen for the evening editing pass. A movement reminder that only fires on one of those devices misses most of the time you're sitting.
What good looks like: iPhone, Apple Watch, Mac menu bar app, Android, browser extension, all carrying the same nudge, all knowing when you've paused on one so the others go quiet too. One pause, all devices. Nudges that travel with you.
Pause it on your phone before a meeting. Did your computer also go quiet?
is the core feature free?
The category has a sneaky pattern: free download, then the actual movement reminder is paywalled. You install, the trial gives you a few days of nudges, the nudges go away unless you pay. Movement is a public health thing. Paywalling the basic reminder is, charitably, off-brand for the category.
Reasonable: paid tiers for power features (lock-screen alarms, screen takeover, health-app writes, custom routines, premium aesthetics). Unreasonable: paywalling the actual reminder. If the trial ends and the nudges end, the app's economics are pointing the wrong way.
What happens to the basic reminder after the trial expires? If it stops, choose differently.
what does it know about you?
A movement reminder needs roughly three things: when you sit, when you move, and how often to nudge you. It doesn't need your email, your name, your weight, your gender, your fitness goals, your phone contacts, or a third-party advertiser's tracking pixel. The list of things a good one needs is short.
What good looks like: no account, no required sign-in, all the state lives on your device, no third-party analytics, no ad networks. If your move count needs to roam between devices, that happens through end-to-end-encrypted sync, not "the cloud" generally. Privacy is a feature decision, not a policy paragraph.
Can you use it without creating an account? If no, what is it doing with your identity?
who's behind it?
The last criterion is the one nobody talks about. A movement reminder is a long-term relationship; you're going to see it every hour for months or years. The economics of the company that makes it determine, over time, what the app becomes.
Some patterns to look for. Venture-funded companies eventually need to grow user counts and revenue per user, which tends to pull movement reminders toward dashboards, subscriptions, and engagement loops. Open-source tools tend to stay simple and tend to be desktop-only. Indie makers tend to be lovely but unpredictable; they have day jobs. Nonprofits (this is us) tend to be slower-moving and oddly stable, because the people running them are doing it instead of doing something else, not as a step on a ladder.
None of these are wrong. They produce different apps over time. Pick the one whose long-term incentives line up with what you want from the relationship.
Read the "about" page. Do you trust the people behind it to still want what you want from the app in three years?
What we built, against this rubric.
Honest disclosure: we made an app in this category and you're reading our website, so consider everything below biased. With that said, here's how Supermoo scores itself against this framework.
Reach: background notifications on every platform, an opt-in lock-screen alarm on iPhone 26+ that rings through silent mode, an opt-in screen takeover on Mac. Attention: no streaks that punish, no leaderboards, no red guilt dashboards. You can pause for any duration, including "until you say so." Even Dracu-Moo, the villain cow, is gentle. Devices: iPhone, Apple Watch, Mac menu bar, Android, Chrome. One pause syncs everywhere via end-to-end-encrypted iCloud key-value sync (between Apple devices) or the underlying account on Android. Free: the hourly nudge is free, forever, on all devices. Premium unlocks the lock-screen alarm, the Mac screen takeover, Apple Health write, and a few quality-of-life extras. Privacy: no account required, no third-party analytics, no ads. Apple Health is opt-in and only writes (never reads). Who's behind: a 501(c)(3) nonprofit (Reweave, Inc.) whose actual mission is making slow films for children. We sell premium to fund the films, not to grow a number on a dashboard.
If you ran another candidate through the same six criteria and it scored as well or better, we'd respect the decision. Someone moved. That's the actual win.
Other movement reminder apps worth knowing.
We don't want to pretend we're the only option, because we aren't. The movement-reminder category has existed longer than Supermoo, and several of the apps in this space deserve a real introduction, especially on the page where we explain why we built our own. Listed alphabetically. Descriptions are factual, drawn from each app's public listings, with our honest take on what each does well.
A guided movement break app with stretching and mobility routines, full-screen alerts, and a character of its own. Runs on iPhone, Android, and Apple Watch. Free tier with a paid subscription for the full library.
Notable for: the depth of its guided-routine library. If you want someone telling you exactly which stretch to do, Moova has the most-developed answer.
An open-source break timer with micro-breaks, longer breaks, and an optional strict mode. Runs on Mac, Windows, and Linux. Free, no account, no ads.
Notable for: being entirely open source, with a vibrant contributor community, and never asking for anything. If you want a desktop reminder with zero strings attached, Stretchly is the one.
A long-running Mac break app that gently fades the screen at break time, supports normal and micro breaks, and respects idle time so it doesn't nag when you're already away. macOS only. Free with optional paid support tiers.
Notable for: the screen-fade UX (less jarring than full-screen alarms) and over a decade of maturity. It was here before most of us.
An open-source tool focused on breaks and repetitive strain injury, with adjustable enforcement. Runs on Windows and Linux. Free.
Notable for: being the most rigorous option for RSI-conscious users, and for surviving more than a decade of evolution. The interface feels older than modern apps because it is; that's a feature for some.
If you read any of those descriptions and one sounds right, give it an honest try. We'd be happy to be your fifth choice if four of them get tried first. What matters is that you find one you'll leave installed. The chair was never going to interrupt itself.
Why we describe rather than tabulate.
Earlier versions of this page had a side-by-side table putting us against the apps above on numerical attributes. We took the table down because tables age badly: the moment another app ships an update, the table is lying.
What you see instead is description-based: each app introduced fairly, plus the criteria framework above that you can apply to any of them yourself. We'd rather give you the framework to decide than pretend a table from June 2026 still tells you the truth in 2027.
If after reading this you go install a different movement reminder, that's still a win. Someone moved.
or just try ours and see if you like it. free.
Free, no account, on iPhone, Apple Watch, Mac menu bar, Android, and Chrome.
If it doesn't pass your version of the six criteria after a week, delete it and we won't take it personally.
