Verdict
The clearest difference is in-app purchases: Demae Robo at none against YomiFlash's 1. Demae Robo also leads on update cadence (every 3 months vs every 10 months). YomiFlash's advantage is ads (none vs shown) and iOS requirement (7.0 vs 15.0). On price and device support there is nothing between them.
