iPhone or Android for Nightscout

Hello! I’m new to the group. We currently use an android based phone with Nightscout/xdrip+ for our son. We were looking at changing his phone to the iPhone 11. Does anyone use an iPhone with Nightscout? We want to continue using Nightscout. I’ve read a lot about sugarmate and Nightscout. Appreciate any feedback or help with this! Thanks!
