     <string name="description">The original maintainer, AWAiS, made InstaGrabber as a small and basic little personal app with intentions of [steali-]downloading posts off Instagram. Very unfortunately, this was abandoned and me, Austin Huang, took over the ship. [Let\'s hope that\'s at least a lil\' bit cash money.] After all, this app is fully open source, ad-less, and tracking-less [aside from what Instagram knows]. Even if you don\'t care about downloading stuff [like me], it\'s still a great Instagram client to use!\n\nGot questions [or just wanna talk]?
