Verdict
The clearest difference is price: SimplyRead at Free against RFCReader Pro's $1.99. SimplyRead also leads on update cadence (weekly vs every 3 months). RFCReader Pro's advantage is in-app purchases (none vs 1) and iOS requirement (11.0 vs 16.0). On ads, monetization model and device support there is nothing between them.
