there is nothing on the app you can get with sweatcoin only, officially the only way to get anything with this is spending real $$. free subscribers get things you could get for free on other websites (free trials, samples). they're just ads that you're paying for with fake money. You still have to pay shipping with actual $$, a classic scam. It'll take you 10+ years to afford a giftcard. I can't find any info on how legit their charity is, which is the only reason to keep it, if it's real.
