FlexiFone enables you to get a Multi-Network eSIM which would enable you to access EE, O2, Vodafone & Three's network in the UK. This means that you will always have the best network coverage across the UK. Best part about this is that you can keep your current or primary number, and use the FlexiFone eSIM for data. Your eSIM / SIM will automatically connect to the cellular network with the strongest signal, hence enabling you to have the best coverage even in the countryside, and dense city centers. We do offer Physical-SIMs as well, if you do not have an eSIM-enabled device. Getting started is simple, just download the app, select a plan, and setup your eSIM / Physical-SIM and you're good to go!

Verdict
The clearest difference is in-app purchases: FlexiFone at none against AR Protractor's 1. FlexiFone also leads on iOS requirement (14.0.0 vs 26.0). AR Protractor's advantage is update cadence (every 3 weeks vs every 2 months). On price, ads and device support there is nothing between them.
