Verdict
The clearest difference is rating: DIFF Eyewear at 5.0 against FYTOO's 4.2. DIFF Eyewear also leads on review sentiment (78% vs 36%) and ads (none vs shown). FYTOO's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 18.0). On price, update cadence and in-app purchases there is nothing between them.
