Had a question when it comes to the aRFR and the iRFR. I have an android phone and have liked using it to aid in channel checks. I have been contemplating buying an iPad as I have heard there are more features on the iRFR, specifically being able to follow along and take notes on the cues. If I wanted to do this would I need to pay for two apps? or is there anything in the works to register the app to a person so I can have it on my two devices?
I'd also wonder when I upgrade my phone down the line will I need to purchase the aRFR app again?
