Spin the City: Bike Tracker

Your bike ride, with a wheel attached. Spin the City picks your next challenge at random, then makes you go out and earn it. Ride, hit the target, collect the coins, keep the streak alive. SPIN FOR A CHALLENGE Three spins a day. The wheel hands you a target — distance, a sprint, a climb, a night run, an early start — in one of four rarities. Common pays flat. Legendary pays four times over, and turns up about once in every seventeen spins. TRACK EVERY METRE Full GPS recording: live speed, distance, moving time, elevation gain and top speed. Recording keeps running with the screen off, so a long ride never gets cut in half. Numbers are set large enough to read on the handlebar at a glance. HONEST NUMBERS A phone sitting at a red light still drifts on GPS, and most trackers quietly bank that as distance. This one doesn't. Fixes with poor accuracy are dropped, sub-two-metre jitter is ignored, impossible jumps after a lost signal are rejected, and elevation only counts when the vertical fix can be trusted. Average speed is measured against moving time, not total time. EARN IT BACK Ten coins per kilometre, one more for every ten metres climbed, plus the challenge reward on top. Keep a daily streak going, climb the levels from Rookie to Mayor of the City, and unlock achievements as the totals stack up. SEE YOUR LINE Every ride is saved with its own route, drawn and colour-coded by speed — blue where you were cruising, orange where you were flying. Distance, climb and top speed add up across everything you have ever ridden. YOUR DATA STAYS YOURS No account. No sign-up. No servers. Spin the City makes no network requests at all — there is nothing to leak, nothing to sell and nothing to log in to. Your rides live on your phone, and they leave with it. Built for city riders: commuters, loop-chasers, and anyone who rides better with a target in front of them.
