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. ## Key features - 0-60 mph and custom speed range timing - Distance measurement (1/4 mile, 1 mile, etc.) - Automatic standing-start detection - GPS and BLE OBD-II adapter support - Detailed run analysis (graphs, splits, G-force) - Apple Watch companion app - Vehicle profile organization ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/devim-gps-0-60-and-drag-timer/id6761691878/reviews.md ### 3/5 — It’s okay *2026-07-15* Did multiple pulls 60-130 and got a 1.8 uncertainties each time. Which means I could be running 7’s or not. So yeah could very well be my gps signal but I was closer to the city so I couldn’t see it being gos more than the app not holding a stable connection? **Developer response:** Thanks for the feedback. With ±1.8 s uncertainty, the phone’s GPS was not precise enough during this pull to confidently confirm a result in the 7s. This reflects the speed data reported by the phone, not necessarily a lost connection. Devim GPS reports the uncertainty so you know when a result should not be treated as exact. We agree this needs to be clearer, and we’ll improve how GPS quality and timing confidence are shown in the app in next version. ## Frequently asked questions about Devim GPS ### What is Devim GPS?

APPLE WATCH • Follow live speed, ready, measuring, and completed states, distance progress, trip statistics, and recent results from your wrist. • Switch between Speed, Distance, and Trip, adjust targets, and use trip controls on Apple Watch. • Away from the iPhone, Watch GPS works as a standalone speedometer. Recording measurements still requires the connected iPhone with Devim GPS open. MORE DEPENDABLE MEASUREMENTS • Standing starts now filter stationary GPS and motion noise and wait for confirmed movement before timing begins. • Completed runs are safeguarded as soon as they finish and can recover after an interruption or relaunch without creating duplicate records. • Once a measurement is armed, its mode, target, data source, selected vehicle, and standing-start settings remain fixed until it ends. SMARTER OBD SETUP • Guided BLE OBD-II setup now includes live-speed verification, automatic reconnection, easier adapter management, clearer troubleshooting, and GPS fallback. • Some Tesla vehicles can opt in, vehicle by vehicle, to experimental CAN speed input when standard vehicle-speed data is unavailable. Support varies by model; this beta remains untested on some vehicles. SHARING AND CLARITY • Choose whether result cards include the graph, speed splits, and location; Pro can optionally attach a measurements CSV. • Clearer timing evidence shows the GPS/OBD method, sample and signal context, alignment, and result status without overstating small differences. POLISH • Added Keep Screen Awake and easier access to support, with improved error handling, accessibility, small-screen layouts, and localized text.
