Verdict
The clearest difference is in-app purchases: Fiberizer Plus at none against otsora's 1. Fiberizer Plus also leads on device support (3 vs 1) and iOS requirement (13.0 vs 18.6). otsora's advantage is update cadence (every 4 months vs every 27 months). On price and ads there is nothing between them.
