How people cheat step challenges, and how to stop it
By Joseph Tung, who makes Stepr · Updated October 16, 2026
Almost every step challenge that ends in an argument ends there because of cheating, or the suspicion of it. The good news is that the common tricks are few and well known: typing a number, editing a screenshot, adding steps by hand in the Health app, installing an app that writes fake steps, and shaking the phone. Most of them disappear the moment steps can only come from a device. Here is each one, and what stops it.
Typed totals and edited screenshots
The easiest cheat is the one most challenges invite: a shared spreadsheet or a group chat where everyone reports their own number. Nobody has to do anything clever; they just round up, or post a screenshot from a good day. Screenshots are trivially edited and impossible to verify.
The fix is structural rather than social: do not accept reported numbers at all. If steps arrive from each person's phone automatically, there is nothing to type and nothing to screenshot.
Steps added by hand in the Health app
Apple Health lets anyone add a step entry by hand, and many challenge apps read Health without checking where the steps came from. A thousand steps typed into Health look the same as a thousand walked, unless the app checks.
Stepr excludes hand-typed Health entries entirely. Health marks them as user-entered, and Stepr never counts them.
Fake-step apps
There are apps whose whole purpose is to write invented steps into Apple Health. To an app that reads every Health source, those steps are indistinguishable from real ones.
Stepr only counts steps from trusted sources: the iPhone's own motion sensor, Apple Watch, and fitness trackers such as Garmin, Fitbit, Oura, Polar, Withings, COROS and WHOOP. Steps written by any other app are ignored, and the league can see which device recorded each person's count.
Shaking the phone
The one trick no app can fully prevent is moving the device itself: swinging an arm, strapping a phone to something that moves, or a gadget built to rock it. The motion sensor counts the movement because, to it, the movement looks like steps.
In practice this matters less than people fear. It takes real effort to fake thousands of steps a day, every day, and it shows: a sudden jump to an implausible total from someone who has never walked that much is visible to everyone in the league. A rising daily goal also helps, because faking one big day does not win anything when each day is judged on its own.
Rules that settle it before it starts
Write down three rules before day one and most arguments never happen: steps come only from a phone or a watch, nothing typed or screenshotted counts, and the organiser's decision on anything odd is final. Then pick a tool that enforces the first two for you.
Stepr was built around exactly that. Steps come from the motion sensor and trusted Health sources, hand-typed and untrusted steps are excluded, each report is signed by the phone with Apple's App Attest so it can only come from a genuine copy of the app, and everyone sees which device recorded each count.
Questions people ask
How do people cheat in a step challenge?
Mostly by typing or rounding up their own totals, editing screenshots, adding steps by hand in the Health app, using an app that writes fake steps, or shaking the phone. All but the last disappear when steps can only come from a device.
Can you fake steps on iPhone?
You can add steps by hand in the Health app or with a fake-step app, and you can shake the phone. Apps that check where steps came from, as Stepr does, ignore hand-typed and untrusted entries, so only movement of a real device counts.
How do you stop cheating in a step challenge?
Do not accept reported numbers. Use a tool that reads steps from each phone automatically, excludes hand-typed Health entries and untrusted apps, and shows everyone which device recorded each count.
Does Stepr count steps added manually in Apple Health?
No. Steps typed into Health by hand are marked as user-entered and Stepr never counts them. Steps written by apps outside its trusted list are ignored too.
