Verdict

The call

The clearest difference is in-app purchases: Hape Engine at none against PrepNote's 1. Hape Engine also leads on ads (none vs shown) and iOS requirement (8.0 vs 17.5). PrepNote's advantage is update cadence (every 7 months vs every 19 months). On price and device support there is nothing between them.
