User reviews

Airports option gone after upgrade to iPhone 17

Great app while it was working on iPhone 14 Pro Max but on 17 Pro Max the Airports selection have disappeared. It is all enabled in Motion & Fitness and set to “precise” and “when using”.

Unfortunately not worth it.

Manually entering the barometric pressure (trying all the options) results in over 145,000 ft in error!

Response from developer

This usually means you did not give the app permission to use Motion & Fitness tracking (or you have that disabled in your Motion & Fitness settings on your iPhone, which then blocks the Watch as well).

Clear Altimeter

The Altimeter is very clear and with the different options to set the base pressure it is ideal for my use. I would like the addition of an alarm you could set when reaching or deviating from a set height.

Non functioning complication on WatchOS 10.3 Beta

I bought this only for the watch face complication. Two problems with that: The elevation does not appear in the complication, only dashes. And the huge logo means if the elevation did appear, it would be a tiny font. Remove that logo please.

HTTP error on receiving pressure from airport.

It says Error: Unable to access server. HTTP error 404 every time I try to get my local airport pressure. Not a great experience considering I’ve paid for this.
