Off-Road Altimeter · iPhone

Stack the bucks.
Earn the ridge.

Measure every ride in Bucks — one thousand vertical feet each. Barometric altitude, unlimited log, shareable summit cards. Built for overlanders, weekend warriors, and anyone who counts their weekends in elevation.

The System

One app, five surfaces.

BuckUp shows up where the ride actually happens — on the Home Screen, on the Lock Screen mid-climb, on the share sheet after you stop. Every surface pulls from the same barometric engine. Every screen earns its space.

Named Peaks

Sixty hand-picked US climbs — Rockies, Southwest, Sierra, Cascades, Appalachians, Alaska. Updated every release.

What Ships Day One

Built like an instrument, not an app.

Every screen earns its space. Every number is a real measurement. No social feeds, no notifications to keep you coming back. Just the gauge, the log, and the ridge.

01

Barometric Accuracy

Your iPhone's pressure sensor reads altitude directly. Smoother than GPS, works without cell service, calibrates itself as you climb.

02

Unlimited Log

Every session saved locally. Date, altitude, gain, Bucks earned. No cap, no cloud sync required, no subscription.

03

Named Peaks

Sixty curated US climbs spanning nine regions. Ride to a peak on the list and it stamps your log automatically.

04

Buck Shot

One-tap shareable card stamped with your rig, altitude, and peak. The kind of thing that lives on group chats.

05

Register Your Rig

Year, make, model, trim, callsign. Eight tribe emblems — Jeep, Ford, Toyota, Dodge, Chevrolet, GMC, Land Rover, Subaru.

06

Milestones

First Buck. 10 Peaks. Mile High. 100 Bucks. Earn stamps as you stack — more unlock across v1.x.

How It Works

Three taps. Then drive.

Saddle Up

Tap SADDLE UP at the trailhead. The gauge begins tracking altitude and gain — barometer first, GPS as a backup. No account required.

Drive

Mount the phone and go. Live Activity + Dynamic Island show altitude at a glance. Widget on the home screen too, if you've unlocked it.

Log It

Tap LOG IT when you stop. Buck Shot captures a shareable card stamped with your rig. Your session hits the log forever.

Pricing

Core app is free. Two unlocks, if you want them.

No subscriptions. No trials. Pay once, own it forever — receipts tied to your Apple ID, restore on any device.

Frequently Asked

The answers, straight.

When does BuckUp hit the App Store?

v1.0 is in late-stage beta. Public launch is imminent — drop your email above and we'll notify you the day it's live. TestFlight invites for a small beta cohort go out first.

What does a Buck actually measure?

One Buck = 1,000 vertical feet of elevation gain in a single session. 2.5 Bucks is a serious day out. 5+ Bucks is a full-send alpine run. Your lifetime Buck count is your vertical odometer — the more you stack, the more ridge you've earned.

Is it really free?

The core app — gauge, unlimited Buck Log, Named Peaks list, Buck Shot, RIG registration, YOU tab — is free forever, no trial, no account required. Two optional unlocks for the home-screen widget ($4.99) and Dynamic Island / Lock Screen Live Activity ($4.99), or $7.99 for both. One-time, no subscription, never expires.

Does it need cell service?

No. The altimeter uses your iPhone's barometric pressure sensor (on-device, offline) and the GPS altitude fix, both of which work without a signal. You only need service for optional cloud sync of your Buck Log if you choose to sign in.

What vehicles does it support?

Any rig. You don't plug BuckUp into your truck — it runs on the phone's sensors. At Register Your Rig we ship with eight tribe emblems covering Jeep, Ford, Toyota, Dodge/Ram, Chevrolet, GMC, Land Rover, and Subaru, plus a generic "Other Make" path for anyone else.

Will there be an Android version?

Not in the immediate roadmap. BuckUp leans on iOS-specific APIs — CoreMotion, Live Activities, Dynamic Island, WidgetKit — that don't have clean Android equivalents. If Android demand shows up we'll reassess.

Can I use it while driving?

Tap SADDLE UP before you start. Put the phone in a mount. Let it run. Don't interact with the app while driving — hand the phone to a passenger if you need to do anything mid-ride. BuckUp is a souvenir, not a compass.

Is the altitude accurate enough for aviation / medical use?

No. BuckUp is for fun and posterity, not safety-critical use. Altitude readings drift with weather and temperature. Don't use it for aviation, emergency navigation, or any purpose where altitude precision matters to life. Proper charts, compass, and gear always.
