Devim GPS is an enthusiast-built GPS speedometer and performance timer for drivers who want to understand a run, not just save a number. Measure acceleration or distance with your iPhone, inspect the data behind the result, and compare runs with the context that matters. No account or adapter is required to start. MEASURE SPEED AND DISTANCE • Time 0–60 mph, 0–100 km/h, 100–200 km/h, or any custom speed range. • Measure 60 ft, 1/8 mile, 1/4 mile, 1/2 mile, 1 mile, or a custom distance. • Automatic standing-start detection waits for confirmed movement. • Use iPhone GPS on its own or connect a compatible BLE OBD-II adapter. • Hear spoken speed-threshold announcements and follow live speed in metric or imperial units. UNDERSTAND EVERY RUN • Review speed graphs, splits, slope, altitude, G-force, route, and indicators that help you judge the result. • See the timing method, sample rates, signal context, and other evidence behind the time. • Organize results by vehicle and add photos and notes. • Build a clean share card and decide whether to include the graph, speed splits, or location. IPHONE AND APPLE WATCH • The Apple Watch companion is included at no extra cost. • Follow live speed, measurement state, distance progress, trip statistics, and recent results from your wrist. • Away from the iPhone, Apple Watch GPS works as a standalone speedometer. Recording or saving a measurement requires the connected iPhone with Devim GPS open. DEVIM GPS PRO Devim GPS Pro is a one-time purchase. Its core Pro features remain unlocked: GPS + OBD analysis, multiple garage vehicles, side-by-side run comparison, measurement CSV export, and unlimited saved runs. Weather, wind, and other online Pro features are included for two years from the purchase date where services are available. OBD compatibility depends on the vehicle and adapter; a compatible BLE adapter using ELM327-style commands is required. PRIVATE BY DEFAULT No account is required. Saved runs stay on your device unless you choose to share or export them. Optional analytics is off by default. GPS and OBD readings can vary with signal, device, vehicle, adapter, phone position, slope, and conditions. Devim GPS is not certified timing equipment. Configure the app while parked, secure the phone, and perform tests only in safe, legal, closed-course environments. Never operate the app while driving.
