I changed the pressure units to inHg, but the corresponding dial doesn't change the numbers to represent inHg. Did I do something incorrect?
[APP] Alti/Barometer app w/ Tile, Auto Calibration, Notifications and More!

No, you did absolutely right. Unfortunately I'm unable to fix this at the moment because I'm really busy. Keep in mind it's only a graphical issue of the dial, the values are correct!
Works fine on my Gen5. No idea if the Gen4 or older has the barometer though so give it a try.
A quick Google search suggests that whilst not officially listed on the spec sheet the Gen4 does have a barometer, so this app should work perfectly on your watch!
I have the app installed for a few days but it seems I can't get a reading for the altimeter. The tile is also stating a network error when ever I go to it and won't populate the information at all. I have cleared data multiple times but it's the same! Using a TicWatch pro 4G/lte USA variant! Perhaps its not compatible with this wear os watch! I appreciate any info on this matter! Thank you!
Just checked online and it seems your watch does not have a barometer on board which is what will be causing the error. The watch can't read real time air pressure.
Thank you so much for the quick reply! Although it does not work on my watch, you have have a beautiful app here and please continue developing!
Even though there is no onboard barometer I thought it would populate such information through the gps location and weather apps. I guess I assumed too much from my watches capabilities. Thanks again!

No problem, though Its not my app, I am no where near intelligent enough to make any app. I just happened to be subscribed to this thread and got an email about your reply so thought I would help you out.
Cool, thanks for the info! Have a good one! AND, I think everyone is exceptionally good at something that allows their intelligence too shine! App developer or not!
Hi, you should follow the instructions you find on the first post. It's all explained
Calugj,
I follow instruction #1. The problem it's to apk installation. "Installation not done"
Hi, I love your application, it's fantastic.
Recently I am having a conflict problem. I have a Ticwatch Pro 3 GPS, at some point when I do a heart rate measurement from Google Fit or from PulseTic it doesn't work, it doesn't measure my heart rate.
I didn't know what was going on, I did a factory reset, and it worked again. I have been installing all the third party apps I had and the different settings until I detected that it stops working when I install and run Alti-Barometer. It is very strange.
I must say that I also activate til of the app, in case that could be the reason.
Can anyone check the pulse to see if it works for them?

Google's Wear OS lacks many things from competitors... One of these is a Barometer-Altimeter application. So why not building one by getting the inspiration from the best one out in the market?
Read the instructions before installation!
Demonstration
App Screenshots
Tile Screenshot
Tour of the app (gif)
Features
Barometer:
● Real-time pressure display digital
● Real-time pressure red hand indicator
● Graph for the past 6 hours
● Pressure trend over the past 6 hours
● Background collecting of pressure
● Notification for possible storms
Altimeter:
● Real-time altitude display digital
● Real-time altitude red hand indicator
● Graph for the past 6 hours
● Auto calibration of altitude based on weather data
● Manual calibration
TILE:
● Thanks to the Unofficial Tile API: Tile showing pressure and altitude!
Settings:
● Enable / disable storm alert
● Enable / disable automatic calibration of altitude
● Set manual altitude
● Metric / imperial units
● Advanced settings
Installation instructions
● Only supports Wear OS, not standard Android
● Android version must be 8.0+
0 - If any previous version in installed, go to "Settings" > "Apps & Notifications" > "App info" > "Alti-Barometer" > "App Info" > "Clear data" > Confirm
1 - Download the latest .apk file
2 - Install the .apk with adb (tutorial on the third post)
3 - Start the app
4 - Grant the Location permission (optional but recommended, if you want the automatic calibration)
Done!
Update instructions
If you want to update this app to a newer version, uninstall the old version and then install the latest using ADB!
Detailed info about the app
Every 5 minutes a the app will get the pressure from the sensor and store the data.
The weather notification is sent if 4 hPa are dropped in the past three hours.
The trend seen in the barometer is calculated in the past 6 hours.
For the first 6 hours the trend is going to be inaccurate because it doesn't have real data to compare.
Altitude is measured using the barometric formula, considering standard the pressure of 1013.25 hPa.
Issues
Automatic calibration not working on Samsung watches. I don't have a watch to test and I can't fix this bug unfortunally.
Download4Auto calibration of altitude - explanation of the physics
I think this is cool to share
Air pressure depends on your altitude, but since air pressure changes normally, the readings are not accurate if the instrument is not correctly calibrated.
Manual calibration can be done... but it's just not practical! Automatic calibration is instead much better.
Let's start with the barometric formula:
Ph = P0 × e^(-α × h)
with constant α = (M × g) / (R × T)
The app gets your location, then finds thanks to the weather API the pressure P0 at sea level.
Once found P0, I can substitute it in the same formula to finally find the actual calibrated altitude
h = ln(Ph / P0) / - α
Ph is now the reading from the sensor and h is the current altitude
The calibration of the altitude highly depends on how accurate are the weather forecast provided...
From my testing I had a +- 10 m which is considerably good, but it depends from place to place.
ADB Tutorial
1) You will need to install ADB drivers to your computer. Suggested tutorial --> [OFFICIAL][TOOL][WINDOWS] ADB, Fastboot and Drivers - 15 seconds ADB Installer v1.4.3 | XDA Developers Forums (xda-developers.com)
Assuming you are using Windows, you should find a folder named "adb" inside the C drive with some files in it.
2) Place inside this folder the apk you want to install.
3) Enable "USB Debugging" on the device you want to install the apk on. This setting is hidden inside the "Developer Settings", that you can enable by pressing 7 times on the "Build Number" under "Device Info". There are many videos that show this.
4) Open the command prompt inside the "adb" folder. To do so using Windows, just press Shift + Right Click of the mouse and then select "Open PowerShell Window".
5) Connect your smartwatch to the PC with the usb cable.
6) On the PowerShell type "adb devices" without quotes and confirm with enter. Make sure the android device shows a message.
7) On the device press "Allow always" (or something like that).
8) On the PowerShell type "adb install Alti-Barometer1.15.apk" without quotes and confirm with enter.
DONE!
