Verdict
The clearest difference is in-app purchases: ICanEmail Online at none against ERSB Lite's 5. ICanEmail Online also leads on device support (3 vs 1) and iOS requirement (6.0 vs 13.0). ERSB Lite's advantage is update cadence (every 2 months vs every 9 months). On price and ads there is nothing between them.
