Verdict

The call

The clearest difference is rating: Vitamin at 5.0 against Twin Science's 4.4. Vitamin also leads on iOS requirement (12.0 vs 15.0). Twin Science's advantage is ratings volume (77 vs 2) and update cadence (every 2 months vs every 3 months). On price, review sentiment, ads and in-app purchases there is nothing between them.
