Verdict
The clearest difference is ads: O`haitai at none against Optical flow Analysis's shown. O`haitai also leads on device support (3 vs 1) and iOS requirement (8.0 vs 17.7.2). Optical flow Analysis's advantage is update cadence (fortnightly vs every 5 weeks). On price and in-app purchases there is nothing between them.
