Pretty good app but most of its rewards are redeemable only if you're from US and India, there are rewards that are available worldwide but it has low value, others need premium pass: yes, most of its high value rewards(like Discord Nitro, PSN and Play Store GCs) are redeemable only if you have a premium subscription. Gaming Hardwares shipments are available only to US too which is kinda sad. Only use this app if you're from India and US. Enjoy and have fun! :)
