Saving your ZOOM setting when minimized is currently a feature exclusive to PylonCam Pro.
-Wakeye on iPhone loses your ZOOM when minimized
-Wakeye on Android loses your ZOOM when minimized (tested on Galaxy S22 and S7
-iPhone native camera loses your ZOOM when minimized
-Android native camera loses your ZOOM when minimized
So PylonCam Pro didn't just inherit this characteristic from the iPhone, its unique to PylonCam Pro APP.
Many skiers have a phone dedicated to their Pylon Videos. So even if you have an Android phone, you could buy a used iPhone on ebay for your skiing. It avoids the complication of having your phone usage getting tangled up with your ski outings.
Of course they could probably get the ZOOM save feature on an Android if they get to it, but its a big effort for a small market. Steve the developer had to do this out of the "love" for high achievement.
