⚡ Tap once a day

Sprout Network is a mobile-app-based platform that claims to let users “earn digital currency” — called SPROUT — simply by participating via a smartphone.
The official “About” page says their mission is: “digital currency should be simple and within reach of everyday people.”
Key features as advertised:
Invite-only community. They emphasise growth via trusted invites rather than open mass join.
A “24-hour earning cycle” — meaning you tap once a day and your phone app remains active to earn.
Team-based earnings: you invite others, build a “team”, and that boosts your mining-rate or earning rate.
Mobile-first design: lightweight, no heavy hardware, claim of “zero battery drain”.
