Project Overview
Flagg is the “Strava meets Yelp meets TikTok” for every outdoor and indoor activity you can imagine:
climbing crags · basketball courts · beach-volleyball spots · disc golf courses · skateparks · pump tracks · secret swimming holes · pickleball courts · street workout parks · kitesurf launches · you name it.
Instead of searching generic Google pins or outdated forums, users open Flagg and instantly see every spot around them, how busy it is right now, the current conditions, and what the community says.
The Challenge
People waste hours trying to answer simple questions like:
“Where’s the closest outdoor gym that actually has rings?”
“Is the climbing gym renovated yet or still closed?”
“Any flooded tennis courts after last night’s rain?”
“Where can I play pickup soccer tonight in Montreal?”
Existing platforms (Google Maps, Facebook groups, niche forums) are either too generic, completely static, or buried in noise.
Our Solution – Flagg iOS & Android App
A fast, beautiful, community-powered map that feels alive.
Flagg – built from the ground up by Eugeniuses – is the electric, community-powered map app that finally lets people discover and share real-time sports and outdoor spots.
120+ activity categories, user-dropped pins that go live after lightning-fast moderation, instant status updates, 24-hour photos/videos with condition tags, a Snap Map-style live “heat” layer showing how busy each spot is right now, hyper-precise search (“outdoor bouldering <30 km, open after 6 pm, not crowded”), saved-spot alerts, in-app DMs and pickup-game group chats, plus seasonal leaderboards that turned “flagging” a spot into a full-blown haptic-celebrated ritual (the waving-flag animation is now a TikTok meme).
