Marketplace
It's a free-to-download app that has a $5 IAP that is currently $0. The purchase confirmation screen should indicate $0 when making the purchase. Should be under settings ( gear icon ) and top first option, click it for premium and your all set!
Never used before, but sounds good. I’ma regular reader of Soylentnews (spinoff of Slashdot years ago when they went “V2”).
Done. Thanks!
