Verdict
The clearest difference is in-app purchases: Read Boost at none against Predo's 1. Read Boost also leads on iOS requirement (16.6 vs 18.0). Predo's advantage is ads (none vs shown) and update cadence (every 2 months vs every 5 months). On price and device support there is nothing between them.
