Happy iPhone User+

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
