Your professional network, in 3D. Gravity renders your real network — your connections, their connections, and the companies, universities and organizations you share — as a living 3D solar system you can fly through. You sit at the center; direct connections orbit as planets, their connections as moons. Double-tap anyone to re-center the universe on them. EXPLORE • The Orrery — your network as a living 3D star map, not a list • Companies, universities and organizations appear as hubs that reveal the paths between you and anyone • Insight — analytics over your own network: where your people are, what they do, who connects you • Discover people like you through shared experience, skills, schools and paths you cross in the real world (coarse cells only — never exact positions) CONNECT • Realtime chat with read receipts, typing, and groups that scale to thousands • Peer-to-peer voice and video calls • Share photos, videos and large files, resumably • Circles — auto groups from your school, major, entry year and workplace • Live location sharing for meetups — explicit, time-limited, expires on its own YOUR PROFILE • A media-rich timeline alongside experience and education • AI quick-fill: import your profile from a PDF or pasted text • Share-to-see fairness: you see others' photos and résumés by sharing your own Gravity is invitation-based — join with an invite code from a member, and the person who invites you becomes your first connection. Free. No ads. No advertising ID.

Verdict
The clearest difference is ads: Gravity at none against 100k Mentor Challenge's shown. Gravity also leads on update cadence (weekly vs monthly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
