Left the phone in the car on the school run, with a block open. It earned nothing — which is the point. Only walking counts, and that's now been watched rather than assumed.
Screen Time limits
Easy to ignore.
Ten minutes of moving, after you eat
Your apps switch off for two hours after you eat. Ten minutes of moving gives them back early — a walk, the stairs, a run, a ride. Indoors counts. Nothing to log, no photos, no streak to protect.
However you move, your phone works it out on its own. Nothing to start, nothing to stop, nothing to log.
This is the whole reason the app exists. In a 2025 trial, ten minutes of walking straight after a glucose drink lowered the peak that followed — more than a thirty-minute walk begun half an hour later did, though both beat sitting still overall. A 2009 study, this one after a real meal, found a slow and comfortable walk worked too. Both are findings about walking, not promises about you — which is why SugarWalk shows you no numbers about your body and never will.
The three peak heights are to scale with each other; the shape and the baseline are illustrative. No values, no measurement, and nothing about your body — SugarWalk has no sensor for that and never claims one. The chart is the 2025 trial: Scientific Reports (2025), where a ten-minute walk straight after a glucose drink cut the peak and a longer, later walk did not. The 2009 meal study is Applied Physiology, Nutrition, and Metabolism (2009). Read them yourself — they're short.
Ten minutes of your body working — that's the whole bar. However you like to move after a meal, if your phone or your watch can see it, it counts.
No watch needed. Works with the phone locked in your pocket.
Stairs, a treadmill or laps of the hallway are all just walking as far as your phone is concerned — it reads movement, not place, and has no idea whether there's a view. What it cannot do is notice you at all if the phone is on the desk.
Anything the watch records as a workout, credited next time you pick up your phone.
Being straight with you about two things. The research above is specifically about walking — we count the rest because it is the same kind of effort, not because each one has its own study behind it. And it can only credit what your phone or watch was there to see: not a car ride, and not the workout you did while your phone sat on the kitchen counter and your watch was on the charger.
There's no GPS and no location permission in any of this, because SugarWalk never needed to know where you are — only that you moved.
Everything that relies on you deciding, in the moment, works until the moment you don't feel like it. That's not a willpower problem — it's a design problem.
It works now — on my phone, not in the App Store. Building it was never the risk: the apps that do exactly this have shipped and then gone unfound, and the closest one to SugarWalk has been live for months with no reviews at all. Starting with the finding-people part is the thing none of them tried. Updates land here first, and only when something actually changed.
