## What is Air Power?

Air Power is a density altitude and horsepower dashboard built for tuners and track-day drivers. See the true air your engine is breathing, forecast performance, and keep every location dialed in.

Features
- Live DA, relative horsepower, correction factor, and air density from your current location or saved tracks
- Multi-location library with quick switching and premium unlock for unlimited spots
- Hourly forecast timeline plus extended view to plan runs when the air is best
- Dashboard gauges, stat grid, and interactive DA chart for clarity in the pits
- Widgets for Lock Screen and Home Screen, including multi-location stacks and Live Activity refresh
- Baseline horsepower and DA settings to match your Dyno or build
- Offline manual input with performance calculator for Dyno and shop work
- Unit controls for temp, pressure, altitude, and horsepower displays

Why it matters
Density altitude moves your horsepower target hour to hour. Air Power brings the math, sensors, and forecast into one industrial-grade view so you can chase the best air and make smarter calls at the track, dyno, or garage.

## Version history (last 4 releases)

### 1.0.3 — 2026-04-10

Widgets now update on their own! No need to open the app — your widget fetches fresh weather data directly and calculates real-time density altitude and horsepower potential on every refresh.                                                                     
                                                                                                             
 • Widgets fetch live weather independently, even when the app isn't open                                   
 • Accurate density altitude while traveling — uses your real GPS elevation                                 
 • Hourly forecast data built into widget timeline for at-a-glance trends                                   
 • Improved location accuracy for widget updates                                                            
 • Bug fixes and performance improvements

### 1.0.2 — 2026-02-21

Widget Accuracy Update

In this update, we squashed a bug that caused the home screen widgets to fall out of sync with the main app!

Previously, if iOS paused the app's background refresh, the widget would rely on an outdated weather forecast, resulting in mismatched Density Altitude and HP numbers. We've implemented a strict "freshness" check so your widgets will no longer display stale forecast data.

Your widgets and your app will now stay perfectly in sync, giving you the real-time DA numbers you need, right when you need them.

Thanks for using the app! Drive safe and keep pushing those records.

### 1.0.1 — 2026-01-06

Smarter Widgets
- Widgets now use hourly forecast data for more accurate density altitude predictions throughout the day
- Improved refresh timing ensures your widget always shows current conditions
- Smoother updates with reduced battery impact
