What's New in Density Altitude +

Bug fix: When using Density Altitude outside of cell service, Density Altitude+ now again correctly uses Onboard barometer. The issue was a recently added iOS privacy setting. If you're a current user and are still not prompted to allow the app to access the barometer, you can go into Settings->Privacy & Security->Motion & Fitness and enable access for Density Altitude+ there. Thanks for your support! Reach me at densityaltitude@rateofclimb.com

Improvement suggestion

App works great and is parallel to a Kestrel at actual locations. Would like the option to save locations or drop pins for favorites. This is beneficial for monitoring trends for future outings. Thanks!

Great App but needs Apple Watch Widget

This app is great for its simplicity and ease of use. I also like how the App Store indicates that no data is collected from the app. I just wish it could integrate into the display for the Apple Watch as this is something I often reference when towing in the mountains.

We are in the test stage for this app. It appears reasonabley accurate and consistent. I’m not sure how close it is to the track though. Still assessing

Excellent but wish there was a watch app

By far the best density altitude app. I just wish I could get it as an Apple Watch app with complications for my watch face.
