About

The Usual Suspects

Features
Read full description

The Usual Suspects is the app for your crew — the people you actually run (or ride) with. THE BOARD Every run is a card, not a message that scrolls away. Who's in, who's considering, one tap to RSVP. The next run is always at the top. CREW CHAT THAT KEEPS THE PLOT GIFs, photos, @mentions, reactions — and when someone posts a run or a race, it lands in the conversation as a card the whole crew can join with one tap. RACE CARDS ON REAL PAPER Trail races come as topo postcards, road races as bibs, local 5Ks as ticket stubs. Paste a race link or describe it and the assistant fills in the details. Finish one and it gets the stamp. YOUR SPOTS, ON A MAP Save the crew's regular meeting spots — tap the map, paste a maps link, or use your location — and get directions from every run. FIND YOUR CREW Public crews get a webpage anyone can find. Private crews stay invite-only. Owners choose. Also: direct messages, push notifications that respect your mutes, live typing and presence, and one link that handles invites whether or not someone has the app yet. Free. No ads. Your data stays yours — delete your account any time from Profile.
