Frequently asked questions

Is it really free?

+

Yes. One full analysis per Apple account, for life. Not a trial that expires, not a preview with the coaching removed — the same breakdown the app gives, every aspect and every rep.

Why do I have to sign in?

+

Because the check costs real computing time, and an account is the only honest way to give everybody one without a bot taking a thousand. Sign in with Apple takes two taps on an iPhone and we never see your email if you choose to hide it.

How long does it take?

+

Usually a couple of minutes. App users go first, so when the app is busy your check waits its turn. It always runs. You can close the tab and come back on any device, because the result is tied to your Apple account.

How should I film it?

+

From the side, phone steady, whole body in frame from head to feet. One set is plenty. Good light helps more than a good camera.

How long can the video be?

+

Up to four minutes and ten seconds of actual lifting. Upload something longer and you drag a slider to the set you want checked, which is what you want anyway — one set gives a sharper reading than five.

What happens to my video?

+

It is deleted within 24 hours. We never publish it, never show it to anybody, and never use it for anything but your own analysis. Nothing you upload is ever publicly reachable.

Do I need the app?

+

Not for this. The app is for the set after this one: it remembers every session, shows whether you are improving, and never queues.

You must be 16 or older to upload a video. Clips are deleted within 24 hours unless you ask us to keep them. To have something removed, or to report a video, emailhello@corect.app.
