[APP] Alti/Barometer app w/ Tile, Auto Calibration, Notifications and More!
- Thread starter calugj
- Start date
You are installing the app on the phone. It won't work. You have to install it on the Watch... Follow the guide on the first post!
I currently don't have other accounts.
Actually the development of this app is suspended.
In order to use the automatic calibration the app needs to access to weather data from an API service. That service is free only for a limited number of requests. The limit has lately been reached. In fact I deleted the link for the download of the app. Any other person that uses this app would cause an error to due to the limit reached.
One single donation won't let me afford the paid version of the service to keep this project running. But I also want to keep the app free to the user. I can't spend my own money on something to be used by people on the world for free.
I'll try to check if there's a 100% free provider, and if I find one I will update the app to use that. But before this happens, I don't accept donations because I don't know if this project is going to continue.
Thank you, but, I don't have any Windows device.
It's possible to install with Apple device?
I'll try with this instructions,

Hoping this gets attention again. Missing it from my watch3 now that I have the watch4 on wear
By popular demand, after almost a year: Alti-Barometer 1.16
- Bugs fixed
- Found a solution for the user limit. It will work for quite a long time!

Glad to see this back running. One question, is there a way to support API 25 (Android 7.1.1)? Would love to have it on my ZTE Quartz with a barometer but it's Android base is still API 25 unfortunately.
Hi, I'm also Galaxy Watch4 user and I'm having problem with this app... Automatic calibration doesn't work (it shows 'never') and barometer shows 1000hPa always as base. But it works when I go up or down....
Reboot your device and make sure it's connected to the internet (WiFi or Bluetooth to a smartphone). Calibrations happen every 4 hours so you might have to wait. Barometer is working fine I guess.
I'm waiting whole day and still "calibrated never". Bluetooth connection and internet access is for sure all the time. Barometer works, but it shows 1000hPa where real pressure is 1025 currently (checking on my weather station and also at local forecast)
The value you see in the barometer section is the raw data that the sensor outputs. There is no calibration on that side. You can check this by using another app that shows the sensor data. In my huawei watch 2 I used to have a test mode hidden in the settings where I could see all the sensor values, including the barometer.
As you said air pressure decreases when climbing up, so it might be that the station is at a lower altitude than you are now. If you live in a hilly city this is plausible. But these are just assumptions.

32Introduction
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

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!
