DOWNLINK is a sports telemetry camera. It records your ride and draws your speed, lean angle, G-force, altitude and route onto the video — saved into the file. INSTRUMENTS FOR EVERY ACTIVITY • Motorcycle: lean angle arc, deepest lean each side, G-force • Car / Track: route panel, cornering G, 0–100 and 0–60 timer • Bicycle: grade, elevation strip, climb and descent • Ski / Snowboard: slope, vertical drop, run count LIVE MAP The minimap turns with your heading, zooms out as you speed up and draws the road you have ridden over Apple Maps. Switch it off in Settings when a start or finish should stay private. ONE-TAP REEL When you stop, DOWNLINK finds the best moments in the telemetry — top speed, deepest lean, tightest hairpin — and cuts a 15-second vertical video: the route draws itself on the map, then each moment slows into its peak. Ready for TikTok, Reels and Shorts. RIDE SUMMARY AND SHARE IMAGE Top and average speed, distance, climb, route and place name on one page. Make an image of the ride with the route on the map, with the start and finish hidden if you like. HONEST NUMBERS Every value comes from this phone's own GPS, barometer and motion sensors. When a sensor has no reading, the display says SIM instead of guessing. Lean and G assume the phone is mounted upright; phone GPS updates about once a second — a good record of the ride, not timing equipment. PRIVATE BY DESIGN No account, no ads, no tracking. Your videos and rides stay on your phone. Free: record with one activity and the Drive instruments. DOWNLINK PRO unlocks every activity, the ride summary, the share image and reels without the watermark with a single purchase. Screenshot and preview footage: A. Thiessen, roadstertouren, J.
