Verdict
The clearest difference is in-app purchases: OCR Scanner at none against Any Formula's 1. OCR Scanner also leads on iOS requirement (13.0 vs 18.0). Any Formula's advantage is ads (none vs shown) and update cadence (monthly vs every 4 months). On price and device support there is nothing between them.
