Sick of paying a monthly subscription to ride through a cartoon island? Incyclist is different. No monthly fee. No fantasy world. Just real places. Ride real filmed routes from around the world. Import any GPX file and watch it come to life in Google Street View — revisit that vacation climb, or ride your local loop, from your own trainer. Add structured workouts to keep your training on track. All free, and open-source from day one. Fits into the tools you already use: • Sync GPX routes from Komoot • Sync workouts from intervals.icu • Upload completed activities to Strava and intervals.icu • Virtual Shifting — change gears with a Zwift Click or on-screen gestures Connects to your Bluetooth (BLE) or Wi-Fi (Direct Connect) smart trainer, power meter, cadence sensor, or heart rate monitor — no extra hardware needed. Unlike many "free" apps, we don't monetize your data. Incyclist doesn't store personal data — only short operational logs (sensor/trainer communication, session ID) used to fix bugs and improve the app, automatically deleted within 14 days. Nothing is sold or shared, with anyone, ever. It can even run fully offline for local rides. You'll only need a connection for online features like Strava, intervals.icu, Komoot sync, or Street View.
