Instruments for Wear OS (Android Wear)

This app integrates our altimeter, speedometer, GPS tracker, stopwatch, compass app and more all in one app. You can run all instruments individually as normal apps, watchfaces or complications. Additionally the "Instruments" app and watchface integrates them all in one interface.

Features of the full version only:
- Graph and map display on watch
- History of recordings
- Full customization options

This app is compatible with all Wear OS smart watches.

e.g.
- Sony SmartWatch 3
- Fossil Q (Explorist, Marshal, Founder, Venture, Wander, ...)
- Ticwatch (E, S)
- Michael Kors (Bradshaw, Sophie, ...)
- Huawei Watch (2, Leo-BX9, Leo-DLXX, ...)
- LG Watch (Urbane, Sport, R, Style)
- ASUS ZenWatch (1, 2, 3)
- Samsung Gear Live
- TAG Heuer
...and many more

If your watch doesn't have a barometer this app can use your phones barometer as well. If your watch doesn't have built-in GPS this app can use your phones GPS as well.
If your watch doesn't have a compass the astro functions will still work.

If your watch is not listed, please check if your Smartwatch runs Wear OS (former Android Wear).

I think it will be a great application in the future. I mainly use the altimeter. Unfortunately, the altimeter calibration process is very imprecise. I live at an altitude of 220m above sea level, in the evening the altimeter shows 202m and this morning it showed 160 !! Perhaps you should enter the auto-calibration button based on SRTM and GPS data? Another option is to manually enter pressure at sea level. However, the best method would be using METEO + SRTM + GPS (remember about places without internet access) Manual correction of the height is unacceptable to me, because the man then forgets about such a correction. Thanks for watchface - please add more configuration option as I described in email.

I use the application on Tag Heuer 45 with Wear OS installed on iphone xr. The application cannot get altimeter data from phone. When I try to disable ‘altimeter from phone’ button i get a message that my handheld device is missing companion app. However, There is no companion app for IOS. I wrote about this to Wear OS developers and they dont care. Altimeter reading is a fault of Wear OS. If you can provide a companion app fot IOS it would be great.

This is not compatible with Galaxy Watch 4 as Wear OS is not. Always says will install soon and never does. Contacted developer twice via email for a refund and never hear back.

It does what it says if does, and I purchased apps from them before. To the people that are hard on this company they are a small company and have supported Wear OS / Android Wear over the years but I support them because the apps the build I find use. We all see value for Wear OS as users "despite reviews saying well I can just use my phone", the way "appfour" supports Wear OS I be very surprised if "appfour" was not like us Users that never lost faith.

It's a battery vampire! Altimeter drains Samsung Watch 4 in just a few hours. Oximeter seems incompatible. Otherwise, apps show promise.

Purchased the full version, but it still shows 'free version' on the app. Waste of money, poorly developed.

Don't install. It's a scam. It took my money twice and nothing on the smartwatch. I would like to re eive full refund. Not working and those so called instruments its a not working joke.

Great and accurate. The only app ive ever paid for. Thd only thing i dont like is i cant use the compass with my full guard 2.5. Also is there a way to use the 12 hour method for time.

It would be a good app if it worked it doesn't show elevation and it freezes up my watch I tried other apps and they show elevation they use GPS to do so
