Drive turns the phone in your pocket into a telemetry logger for the days you actually care about driving. Mount it on the dash before you set off. Drive reads the sensors already inside your iPhone — the accelerometer, the gyroscope, the barometer and GPS — and records what the car did. Then you can export your session as a poster to share. --- THE GAUGE A live friction circle shows the forces on the car: braking up, throttle down, cornering left and right. The border is one g. A blue trail keeps the last two seconds, so a corner's shape stays visible. Peak markers hold the hardest moments of the session. Your speed, your max g-force and the outside temperature sit alongside it. --- HUD MODE On a windshield mount, tap the windshield button and the screen turns see-through: the road ahead fills the background, lined up with where you sit, your stats on top. Nothing from the camera is recorded or leaves your phone. --- PICK YOUR FOUR Tap + to choose the four stats under the gauge: • Turns and best corner speed, distance, elevation and grade, density altitude • Butt dyno — your estimated peak horsepower, from how hard the car pulls. Add your cars once and switch between them in a tap. • 0-60 mph, 0-100 mph, 1/4 mile and 1 mile — your best standing-start times. Track use only. --- RECORD THE RUN Press record and Drive keeps the whole drive: the route as a GPS trace, a pin where you cornered hardest, and the stats that go with it. Every drive lands in a history, one card per drive with its own map, and any drive can be sent as a poster. --- ROADS YOU LOVE Drive remembers the roads you record. Arrive at one again and it can offer to record; on a Friday evening it can suggest a Saturday morning run. --- PLATE READERS, ON THE MAP Automatic licence-plate readers have gone up on most main roads. Drive shows the ones the OpenStreetMap community has mapped: a marker for every camera near you, and a heads-up as you approach one, with the distance and which way the lens faces. The list is built into the app, so nothing about your drive leaves your phone to look a camera up. It is community-mapped and incomplete — no alert does not mean no camera. Drive is a privacy tool, not a law-evasion tool; you are responsible for how you use it. --- WHAT PRO ADDS The live gauge, your speed and the outside temperature are free, and stay free. Pro unlocks the stat cards, the map with its plate-reader markers and heads-up, and the drive history. Try it free for a week with no payment details, then buy it once or subscribe monthly. --- BUILT FOR THE PASSENGER SEAT AND THE PADDOCK Drive is set up before you move and read after you stop: track days, autocross, a morning on a road you love. It is not a driving aid, and nothing in it should be operated while you are driving. Drive asks you to confirm that every single time it opens. --- PRIVACY No account. No sign-in. No ads. Your drives, roads and cars stay on your phone — never uploaded. The camera, in HUD mode, is only ever shown on screen. Drive uses your location for speed, distance, the map, the plate-reader heads-up and road reminders, all worked out on the phone. It sends your coordinates to Apple Weather for the outside temperature, and a car's name to Google only when you tap Find weight. Usage analytics are anonymous and aggregate: no advertising identifier, no cross-app tracking. --- REQUIREMENTS iPhone with iOS 17 or later. Drive needs location and motion access to do anything; both are requested on first open, with the reason shown in each prompt. Use a dash, vent or windshield mount. --- SUBSCRIPTION TERMS Drive Pro Monthly ($2.99 per month) renews automatically until cancelled in your App Store settings. Drive Pro Lifetime ($19.99) is a one-time purchase and does not renew. The free week needs no purchase and charges nothing.
