Screenshots
Description
The Pilot's Choice! A complete, full-featured aviation altimeter running inside your Apple Watch Series 3 or higher! A real barometric Altimeter, not GPS-based. Authenticl Altimeter dial with digital readout! This altimeter allows you to set the field altimeter setting (QNH). The Altitude can be displayed in Feet, Meters, or Flight Level. You can also display the raw barometric pressure. The Kollsman window allows setting the local pressure in either inches of mercury or hectoPascals (millibars). Completely International! Once you load the App from your phone and set your preferences with the companion iPhone App, the watch Altimeter is completely independent of the phone. Use this App without a phone nearby and without any internet connection. Set Preferences directly on the watch by Swiping left. Swipe to the right and see your current density altitude by using the watch crown to set the ambient temperature. Tap the AltAlert button and set a desired target altitude and range. The will show you graphically when you go out of bounds. An extra bonus feature is an oxygen alarm to remind you haptically and visually when you exceed 12,500 ft. The alarm only functions when the Altimeter App is running on the face of the watch! This app is Flight Tested, but NOT FAA TSO-certificated and can not be used as a primary flight instrument! This App only works on Apple Series 3 and later Watches! Remember to allow the app to use the Fitness & Motion sensors in "Settings" Tl;dr: Swipe left to change Units, swipe right for Density Altitude, tap the left button to adjust the Station Pressure. Tap the right button for Alert Alert settings

Developer responded to feedback and improved app immediately. Great app and support. Better support than apps costing 10x as much
After setting watch and iPhone to allow fitness, the app still does not work. The Set Baro button does not appear on watch, and you cannot set alert altitude from watch. It might be ok for 29.92 only.
Can’t get it to alert me. Can’t contact company for help because their webpage doesn’t take my question.
I was impressed by the features and how easy it was to set up a target altitude. The issue that I had this after several minutes, the app will drop off the watch face which would then revert to its standard face. I was not able to figure out a way to set a time out to keep the app open. Unless this is user error (which is certainly a possibility), it’s not nearly as useful as it could be. Using on a series 5 watch. UPDATE Followed the directions to update the “Wake Screen” settings and NOW this is a really useful app. Glad to be some to give it 5 stars. Thank you!
Works great.
Neat app, functions ok but the complication can’t be selected to display in the “My Faces” page of the Apple Watch App. It won’t even show “BaroAlt” on this page. However BaroAlt is shown as a complication on the Complication page. I have a brand new iPhone 11 and brand new Apple Watch 5, so it might take some updating the app. Authors please address, thanks!
Had an issue at first with a bug, but developer quickly addressed my issue, applied an update to fix the bug, and the app works just as it’s supposed to. Best baro altimeter app I’ve seen so far. Maybe a watch complication would be a nice addition to the app, but it’s great as it is! Thank you! I changed my review!
I purchased app today and very happy with it but it does not look like it fits well on the series 4 44mm watch, it looks like an egg shaped display. I hope it’s not the final version and j hope there will be a fix for this because it looks awkward.
Message appears to authorize access to watch barometer. Ok does nothing. Message comes back. Emailed developer. No response. Will adjust review when problem is fixed. I am revising my review. It now works and developer has added instructions. Thank you. My only gripe is that the top and bottoms of the altitude digits are cut off on my watch. I can still read the altitude but it takes a minute to interpret the numbers. REVISING AGAIN. Digit clipping is fixed in latest version. With local altimeter setting the altimeter is quite accurate. So much better than GPS estimates. I can usually get current altimeter setting by asking SIRI. Nice APP
Neat little App! Just took a transcontinental 57 and watched the cabin pressure float up to FL080. Cool!
