Verdict

The call

The clearest difference is update cadence: Vision GPT at every 2 days against memoryOS's every 3 weeks. Vision GPT also leads on review sentiment (100% vs 80%). memoryOS's advantage is ratings volume (16K vs 21) and chart position (#52 vs unranked). On price, rating, ads and in-app purchases there is nothing between them.
