A premium update to nutrition app Wholesome lets you do more than just see what’s in your food. The base app — with all its nutritional information — is still free, but for $2.99, you can unlock the “My Nutrition” and “Food Diary” features.
These give you tools to track your intake of hundreds of nutrients like vitamins, minerals and isoflavonoids. I had to look up what isoflavonoids are, but I definitely haven’t eaten any today (they’re in peas).
