Your professional network, in 3D.

Gravity is a professional networking app that shows your network as a 3D star map instead of a flat list. You are the star; your connections orbit you as planets, their connections as moons, and companies and universities appear as ringed giants that link people together. You can orbit, zoom, tap anyone to see who they are, and double-tap to dive into their own system.

From your real network: your connections, their connections, and the organizations you share — employers and schools. Gravity also notices when you and someone nearby cross paths repeatedly (using a coarse, privacy-preserving location cell, never your exact position) and suggests them as people you may actually know.

Yes — realtime one-to-one and group chat with read receipts and typing indicators, file and image sharing, and optional live location sharing so meeting up is easy. Large groups with thousands of members stay fast.

Gravity is free and invite-only: signing up needs a code from an existing member. Sign in with email or phone, or with Google or Apple. Gravity and Snore Analyzer are separate products with separate accounts.

Yes. On iPhone and iPad, get it from the App Store (apps.apple.com/app/id6804564539). On Android, get it from Google Play (play.google.com/store/apps/details?id=dev.hplab.gravity), or download the APK from hplab.dev/gravity/get. Gravity is also an installable web app (PWA): open hplab.dev/gravity in your browser and choose "Install app" / "Add to Home Screen".

A Gravity-only discovery signal. When two people repeatedly appear in the same coarse area around the same time — the same campus, office district or conference — Gravity suggests they might know each other. Only rough location cells are used, and only to make suggestions.
