Devim GPS turns your iPhone into a speedometer and performance timer. Whether you're testing a 0–100 km/h sprint on a track day or just want a clean, reliable speed readout on the road, Devim GPS gives you the data you need with a minimalistic interface.
Measure 0-100 km/h, 0-60 mph, or any custom speed range with automatic timing, standing-start launch detection, and detailed post-run analysis. Built for drivers who want clean performance data without clutter, Devim GPS combines a classic analog-style dashboard with practical tools for testing, reviewing, and comparing runs.
Use Devim GPS as a live speedometer or as a performance timer for acceleration testing. Set any lower and upper speed range from 0 to 400 km/h or 0 to 268 mph. The timer starts automatically when your lower threshold is crossed and stops when you reach your target speed.
When your lower bound is set to 0, Devim GPS can enter standing-start mode. The app performs a short calibration while the phone is stationary, then uses motion sensors to detect the moment the vehicle begins to move. This helps capture launch timing before GPS speed starts to rise.
Every completed run is saved automatically for later review. Incomplete runs can also be stored and are clearly marked, making it easier to compare attempts, diagnose missed launches, or review interrupted tests.
Key features:
- GPS speedometer with a clean analog instrument look
- 0-100 km/h, 0-60 mph, and custom acceleration timing
- Custom speed range testing from 0 to 400 km/h or 0 to 268 mph
- Standing-start launch detection
- Automatic run saving
- Optional audio announcements at speed milestones
- Real-time altitude display
- GPS accuracy status indicator
- Speed, altitude, and distance review for recorded runs
Each saved record includes detailed analysis tools to help you understand performance beyond a single number. Review speed over time, altitude change, covered distance, and speed splits across the run. Devim GPS also calculates slope and road grade information and provides a slope-corrected time to help you compare runs recorded on different roads more fairly.
Trip statistics are also available, including:
- Average speed
- Total distance
- Elapsed time
- Net altitude change
You can switch between km/h and mph, choose metres or feet for altitude, and enable or disable features such as standing launch detection and audio announcements.
No account required. No data collection. No ads. Your data stays on your device.
Use Devim GPS responsibly and only in safe, legal conditions.
