Altimeter+

I found this to be very accurate having compared it to Ordnance Survey maps spot heights measured in situ.

Thanks for updating. Works great on my mighty Apple Watch 4. Used this app hiking up the Sierra Nevadas but had to keep getting the iPhone out to check altitude, now the Watch version will make life easier. 😃😃😃

I purchase the app as I wanted it to work independently on my Apple Watch 3 LTE. However looking at altitude on the watch often shows a false reading which is only fixed once I calibrate the iPhone X barometer via GPS reference. There doesn’t seem to be a way to calibrate the Apple Watch barometer through forced touch, so I’m left thinking it’s just an extension of the iPhone rather than acting independently?

Great little app. Would like to see a complication for Apple Watch showing the current altitude, hence the 4 stars.

A very useful tool, would not be without it.

Very good and accurate

Perfect. I use it to calibrate my altimeter watch before climbing. Great look and feel too.

Nothing more to say, it does what it says and I've tested it in many locations across the world.

Worked at treat in remote locations to pretty good accuracy!

Fascinating app
