NutCase - Log your nuts. Know your limits.

Most nutrition apps only tell you what's good for you. NutCase tells you where the ceiling is. Log what you eat, see it against your daily values, and browse 13 nuts with sourced nutrition, benefits, risks and real limits — an ounce of Brazil nuts is 988% of your selenium DV, so the app says 1–2 per week, not "eat more nuts." Per-nut allergy severity blocks risky logging. iPhone, iPad, Mac and Watch. Free to track and browse. Educational, not medical advice.
