RYNG - The gym app that calls you.

Most fitness apps solve what to do — routines, tracking, calories. RYNG solves the part that actually breaks: getting yourself there. It calls you — a real phone call, not a notification — before your scheduled workout. An AI coach cuts through your excuses and asks one thing: "Are you going?" No tracking. No routines. Just accountability at the moment resistance kicks in.
