I downloaded Sweatcoin and i received an error “Oups, something’s wrong! Please check your device time and data settings and is not using a proxy” but I don’t use any proxy. I also tried to reset my phone and still received the same error. Im using ios 14.4
Try making the time in your clock/time settings automatic based on your location and then try again.
If the time on your phone is set manually, it can be used to “extend” your day, which is cheating, which is most likely why they have that condition.
In short, set your time on automatic based on region/country/location.
