This should not be allowed on the market. I’ve used it together with Illyrian Smart Oximeter for less than 2 hours and the app started crashing perpetually on startup. Restarting the phone did not help. Had to delete and reinstall it, but now I don’t trust it so am returning the oximeter for a refund. I don’t recommend anyone using this product in the air without having a backup pulse oximeter. Also, the app appears very amateurish. It comes with superfluous features that clutter the interface and appear pointless. For example, it tries to upsell you to get inflight PIREPs and weather reports but the app needs Internet connection for those. In the age of ForeFlight and FIS-B weather through portable ADS-B receivers, offering weather product requiring internet is probably the dumbest idea I’ve ever heard of. Plus why would I need a weather product inside an oximeter app if I have my EFB and Windy. Overall, super disappointed and rating the app and physical product as junk. Apparently it wasn’t tested in basic scenarios since it’s clear from other comments that others have experienced similar problems. The developer response is unacceptable - they say - hey, “please understand that a lot of technology needs to come together to make it work”. Who cares? You didn’t make it work. It’s a stupid simple oximeter. The scope creep in your app made it difficult for you to focus on core scenario. The engineer or two who coded it literally doesn’t know what they are doing.
