Your workout starts when you walk in the door. ooolog automatically logs your workouts using the places you save — your gym, your yoga studio, the climbing wall. Arrive, and the session starts. Leave, and it's saved. No timers, no start buttons, no forgetting. HOW IT WORKS • Save the places where you work out • ooolog quietly watches for arrivals using geofences — no GPS tracking of your movements • Every visit is logged with its duration, automatically • Your history builds itself: streaks, time totals, and your most-visited places BETTER WITH FRIENDS Follow your workout buddies and see the time they're putting in at the places you share. A little friendly accountability goes a long way. PRIVATE BY DESIGN ooolog only monitors the specific places you choose — never your location in general. Your workout history stays on your device and syncs only what's needed to share with people you approve. Sign in with Apple, no ads, no data sold. Ever. Getting started takes one minute: sign in, save a place, and forget the app exists. That's the point.
