Client Overview
About the Project
OnSite Social is a location-based mobile app that helps users in the United States build real-world connections — from professionals seeking real-time networking opportunities to social explorers looking to meet people in their immediate surroundings. Rather than relying on swipe-based matching disconnected from physical reality, the app surfaces nearby users within a tightly defined radius, turning everyday proximity into an opportunity to connect.
Since launching on the App Store, OnSite Social has surpassed 10,000+ downloads, with users reporting a noticeable increase in both casual social connections and professional networking opportunities made possible by real-time proximity matching.
SaaSify Labs delivered full-stack development for OnSite Social — from the Flutter mobile app to the NestJS/MongoDB backend and AWS infrastructure — shipping the MVP to App Store launch in roughly 6 months in 2023.
The Challenge
What Problem We Solved
People regularly cross paths with interesting potential connections — at coworking spaces, events, cafes, conferences — with no way to know who's nearby or open to connecting. Existing social and dating apps optimize for browsing profiles anywhere in the world, not for the people physically around you right now.
OnSite Social needed a way to surface nearby users accurately and in real time, without compromising user privacy or draining battery life — plus a path to let users connect their digital identity (via NFT/MetaMask wallet integration) to their real-world social graph.
What We Built
Core Features Delivered
300ft Radius Discovery
Precise real-time geolocation surfaces nearby users within a tightly defined radius, balancing accuracy with battery and privacy constraints.
Real-Time Presence
Live presence updates show who's nearby and active right now, not stale check-ins from hours earlier.
NFT Marketplace Integration
MetaMask wallet connect lets users link their digital identity and NFT collectibles to their social profile.
Privacy & Compliance Controls
Granular location-sharing controls and compliance safeguards keep users in control of their visibility.
