Short answer
Cronometer is a nutrition tracker: you log foods, exercise, biometrics and notes. [1] Thrive is a plant-food nutrition database: you look up a plant food and read its per-100 g nutrition facts from USDA FoodData Central and UK CoFID, with % NRV (UK). If you want a food diary, Cronometer is built for that. If you want to check a plant food quickly, for free and without an account, Thrive is built for that. You can use both.
