Verdict
The clearest difference is review sentiment: evcc.io at 91% against RCT App 2.0's 4%. evcc.io also leads on update cadence (every 2 months vs every 4 months). RCT App 2.0's advantage is iOS requirement (13.0 vs 16.4). On price, ads, in-app purchases and monetization model there is nothing between them.
