Aviation Altimeter for Watch 4+

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!

New! Many people have asked for this feature, so we have added launch complications for all watch faces. Instant launch to Altimetry! Thanks for your patience!

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

Version 1.04 handles the Series 4 screen sizes better. This should fix the digit clipping. Thanks for revising your review!

Sorry for the delayed response here. We did get a single query on this issue from someone named Stan and we responded the same day to that person’s reply address.
There is nothing wrong with the App. As with so many things in the Appleverse, a user must explicitly give permission to a device to access certain features, barometers included. Most users have already turned this permission on by the time they get the Altimeter App. We apologize for not giving explicit direction for this issue. Here goes the easy fix:

On the paired iPhone, open Apple’s Watch App.
Scroll down the main view to “Privacy”
Turn On “Fitness Tracking”. That’s it! Fitness tracking enables all the motion sensors, accelerometers, and barometer on the watch for use by Apps.

Please consider revising your negative review.

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!

Hi K, Thanks for the review. What you describe is a *!@#Feature#@!* of the Watch. You can change the Watch behavior as described in AppleInsider below. If this change in watch settings helps you, would you consider revising your rating :)

"By default, the Apple Watch acts as first and foremost as a watch, displaying the time when a user raises their wrist. But the settings on the Apple Watch also allow users to have the device operate more like a smartphone, resuming the last activity.

As anyone who has tried exercising with a third-party Apple Watch app knows, after a short period of time, the device will return to displaying the default clock face when they raise their wrist. Luckily, there's a simple fix for those who would rather have third-party apps stay in the foreground.

On the Apple Watch, users can open the Settings app, then select General, and then Activate on Wrist Raise. Scroll down to Resume To and switch the checked item to Last Used App."
