# Hairpin: Mountain Roads — Corners, hairpins, high passes > Corners, hairpins, high passes (iPhone/iPad app by NICOLA GADOLINI.) - Source: https://appshunter.io/ios/app/hairpin-mountain-roads/id6791478023 (this page in markdown: same URL + `.md`) - Developer: [NICOLA GADOLINI](https://appshunter.io/developer/6791478025) - Category: Travel, Navigation - Price: Free - Age rating: 4+ - Requires: iOS 26.0 · 17 MB - Languages: American English, German (Germany), Italian - Released: 2026-09-21 - Data updated: 2026-10-31 ## What is Hairpin? A driving log for people who go to the mountains for the corners. Hairpin records your rides by car and by motorcycle, and measures them by what actually matters on a mountain pass: hairpins, corner radius, elevation gain. Not speed. HOW IT WORKS Hit Start before you set off, pick your vehicle, and go. The app follows the route, counts hairpin points as you drive, and draws the track on the map. At the end you get the map, the numbers, and a speed graph laid out over the distance you covered — so a coffee stop doesn't squash it into a corner. ON A MOTORCYCLE With the phone in its mount, Hairpin measures how far you leaned. No extra sensor: the lean angle is already inside the lateral force, and at the end of the ride you get your maximum lean next to the hairpin count. In a car, peak lateral G takes its place. PASSES GET STAMPED Twenty-two Alpine passes, from the Cuvignone to the Stelvio. Reach the top and the stamp is yours: once, and only by going there. Every badge carries the line you actually drove over that pass — not one drawing for everybody — and shares as an image. HAIRPIN DNA From your rides the app works out what kind of corners you look for: median radius, rhythm, how much climbing you take per kilometre. Then it tells you which passes you haven't ridden yet are like the ones you love. THE ROADS YOU REPEAT GLOW Every ride lights up its own track. After a few months it stops being a map: it's the record of where you actually go. WITH FRIENDS Start a crew or join one with a code. Your people's rides show up in the feed, with headlight flashes instead of likes. You compete on corners, elevation and passes reached. THE OBD PORT Plug in a Bluetooth OBD reader and you'll see engine revs during the ride too. ON THE LOCK SCREEN While you're recording, time, distance and hairpin points stay visible without unlocking the phone. The home screen widget keeps your week's tally. WHAT YOU WON'T FIND No speed leaderboards and no records on public roads: it isn't that kind of app. Speed stays in your own ride telemetry, and that's your business. Your rides start out private: only your crew sees them. Make your profile public and anyone on Hairpin can see them, and they reach the people who follow you. Account and data can be deleted whenever you want, from inside the app. ## Is Hairpin safe? Not enough ratings yet to assess Hairpin. ## Is Hairpin legit?

Hairpins and curves are counted only while you are moving, no more false counts when standing still. New: "Report a problem" at the bottom of the home screen. Discarding a drive now asks for confirmation. ### 1.3 — 2026-09-30 What's new in 1.3 • Invite a friend to your crew with one tap: from the Crew tab, a ready-made message goes out with the App Store link and your crew code. ### 1.2 — 2026-09-24 What's new in 1.2 • Car or motorcycle: choose what you ride. On a motorcycle Hairpin also reads your lean angle, from the phone in its mount. • Ride telemetry: slide along the road on the map and see speed, braking and G-forces meter by meter. With an OBD reader, throttle and engine RPM too. • A new You tab: your rides at the top, to swipe through. Hairpin DNA and your stamps live in two cards that open up. • Rides start on their own when you set off, and end when you stop. • How you drove: after the ride, your braking and cornering read from the accelerometer. None of it depends on how fast you went. • Sessions: on closed circuits, compare your runs sector by sector, with a three-step guide on how it works. • Tiles: in Explore the map lights up wherever you've been, your daily commute included. • Turn the phone sideways and it becomes a dashboard. • Rides name themselves: the pass you stamped, or the road you took. • Hairpin now speaks English and German. • No invitation code needed to get in. • Apple's typeface across the app, snappier buttons and faster maps. ### 1.0 — 2026-09-21 No release notes. ## Apps similar to Hairpin | App | Rating | Price | Category | | --- | --- | --- | --- | | [Trippy: Tips to Trips](https://appshunter.io/ios/app/trippy-tips-to-trips/id6787430679) | — | Free | Travel | | [MotoTrip: GPS Route Planner](https://appshunter.io/ios/app/mototrip-gps-route-planner/id6757126100) | — | Free | Travel | | [Motoavventure - your best ride](https://appshunter.io/ios/app/motoavventure-your-best-ride/id1466210755) | — | Free | Travel | | [Alpi Maps](https://appshunter.io/ios/app/alpi-maps/id1045609978) | — | Free | Travel | | [Route-Finder](https://appshunter.io/ios/app/route-finder/id803666899) | 3.9 (42) | Free | Travel | | [OnOff Trento](https://appshunter.io/ios/app/onoff-trento/id6463413817) | — | Free | Travel | ## More apps by NICOLA GADOLINI - [BikeReady App](https://appshunter.io/ios/app/bikeready-app/id6801170847) - [LIFTOFF - Impila e Lancia](https://appshunter.io/ios/app/liftoff-impila-e-lancia/id6802243946) - [GarageOS](https://appshunter.io/ios/app/garageos/id6802679897) All apps by NICOLA GADOLINI: https://appshunter.io/developer/6791478025 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
