Verdict

The call

The clearest difference is ads: Otum at none against ChartDetector AI's shown. Otum also leads on update cadence (every 5 days vs every 10 days). ChartDetector AI's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 17.0). On price and in-app purchases there is nothing between them.
