FreeStyle Libre w/ Iphone in US

Hello,
I am a 54-year-old type 1 who just started using the FreeStyle Libre here in the US. I get kind of obsessive-compulsive at times and I just want to take the reader and swipe it past the sensor every single minute. If it were possible I would.
My mobile phone is an iPhone 8 and I’ve heard of software compatible with iPhone that would read the sensor.
I’ve looked, but can’t find anything that works. Has anyone had success?
Thank You,
Mary

Here are two Libre piggy-back transmitters that automatically push glucose readings to enable user-set alarms with an external app, like the Dexcom CGM does.

The BluCon works with both iPhone and Android smart phones.
