Rollog: Inline Skate Tracker

Rollog is a GPS tracker built for inline skating — not a running app wearing skates. CORE FEATURES • GPS route tracking: distance, speed, elevation, auto-pause at red lights • Skating-specific calorie model (MET-based); pair Apple Watch for heart rate and fat-burn zones • Skate diary: every session logs place, weather and route automatically; add a note and road photos • Same-route comparison: rides on the same route are grouped automatically — compare with your last ride and your best, and celebrate new records • Share card: real route map + stats + photos in one image • Voice announcements, hydration and long-ride reminders, warm-up prompts tuned to your age • Slope alert: warns when a downhill gets steep and fast • Apple Watch: heart rate and remote control on your wrist ROLLOG PRO (one-time purchase) • Race mode: pace-first dashboard, per-km voice pace and splits, records kept separate from casual skating • Gear management: mileage per skate, wheel-rotation and bearing-service reminders • GPX export with privacy trimming (first/last 200 m) • All theme colors PRIVACY FIRST No account. No server. No tracking. All data stays on your phone.
