Devim GPS: 0-60 and Drag Timer

New version 2.0: 1/4-mile distance runs, OBD support, GPS+OBD analysis, garage, weather/wind, comparisons, CSV export and Pro performance tools.

Devim GPS is a clean GPS speedometer and car performance timer for 0–100 km/h, 0–60 mph, 100–200 km/h, quarter-mile and custom runs.

Set up your test while stationary, place your iPhone securely, and let Devim GPS record the run automatically. Use it for track days, closed-course testing, tuning notes, or simply a clear live speed readout.

MEASURE SPEED AND DISTANCE • Live GPS speedometer with an analog dial • 0–100 km/h, 0–60 mph, 100–200 km/h and custom speed ranges • Distance timing for 1/8 mile, 1/4 mile, 1/2 mile, 1 mile and custom distances • Standing-start launch assist for 0-based runs • Spoken speed-threshold announcements • Metric and imperial units

OBD AND GPS+OBD Use built-in GPS on its own, connect a compatible Bluetooth ELM327-style OBD-II adapter for vehicle speed, or combine both with GPS+OBD analysis. OBD support can help compare GPS speed with vehicle data and review timing after the run.

REVIEW EVERY RUN Each saved run can include: • Measured time and selected range • Speed, altitude and distance charts • 10 km/h acceleration splits • Route map with start and finish markers • Slope, corrected time and result-quality details • Notes and vehicle assignment • Head and Tailwind calculation. (Weather and wind context when available)

GARAGE, COMPARISON AND EXPORT Build a small garage, assign runs to vehicles, compare two saved records, and export detailed GPS/OBD data as CSV. Share a full run detail image when you want a clean result card for friends, teammates or your own build log.

OPTIONAL PRO Devim GPS Pro unlocks advanced tools such as GPS+OBD mode, multiple garage vehicles, run comparison, CSV export, weather/wind analysis and unlimited saved records. The one-time Pro unlock is for core local Pro features; cloud-backed services and future premium feature families may depend on availability or an active subscription.

PRIVACY AND SAFETY No account is required. Your run records are stored on your device unless you choose to share or export them.

Devim GPS is not certified timing equipment. Results depend on GPS reception, OBD adapter behavior, phone placement, road slope, weather and other conditions. Use Devim GPS only in safe, legal environments and never operate the app while driving.
