iPhone
New: automatic calibration — no manual setup needed. Cleaner Road view highlights just the vehicle ahead. Other cars' plates are blurred automatically for privacy.
See how close you're following — before it's too late.
ProxiDrive uses your iPhone's rear camera and on-device computer vision (no LiDAR, no cloud, nothing leaves your phone) to estimate the distance to the car ahead and warn you — on screen, with sound, a spoken alert, and haptics — when you're following too closely.
TWO WAYS TO VIEW THE ROAD
• Road view (default): live camera feed with lane markings, the tracked vehicle boxed, a top-down schematic of the road, and a HUD strip with speed, distance, time-to-collision, safety level, weather and clock.
• Drive view: a minimal, distraction-free big-number distance readout.
SET UP ONCE, OR NOT AT ALL
ProxiDrive can now calibrate its own camera angle and mounting height automatically while you drive — no more manually lining up the horizon. A quick manual calibration screen is still there if you prefer it.
YOUR RULES, YOUR UNITS
Use the international 2-second/3-second following rule, build your own speed-to-distance table, or use the local regulatory table. Distances switch automatically between meters/km or feet/miles based on your region and how close the car ahead is.
PRIVACY BY DESIGN
Other vehicles' license plates are blurred automatically on screen (you can turn this off for dashcam-style use). Nothing is ever recorded or stored. Only a coarse, rounded location is used, for your own speed and optional weather.
HONEST ABOUT ITS LIMITS
In good daylight, distance estimates are typically accurate to within about 15–25%. Accuracy drops at night, in rain, or fog — ProxiDrive lowers its confidence rather than showing a confident wrong number.
FREE, WITH AN OPTIONAL COFFEE
Every safety feature — warnings, time-to-collision, lane overlay, calibration, every distance rule — is free, forever. If you'd like to support development, buy the developer a coffee (a one-time purchase, not a subscription) to unlock two extras: the weather widget and HUD layout editing.
ProxiDrive is a best-effort driving aid, not a certified safety system. It does not replace your own attention behind the wheel.
