Verdict

The call

The clearest difference is ads: FastFit at none against DiyetAI's shown. FastFit also leads on update cadence (every 3 days vs every 8 days). DiyetAI's advantage is device support (3 vs 1) and iOS requirement (15.6 vs 17). On price and in-app purchases there is nothing between them.
