See every meal at a glance. A visual food diary on your calendar. THE PROBLEM You want to track what you eat, but you forget to record meals or miss taking a photo. And even when you do track your health, Apple Health gives you numbers without context โ€” no baseline, no averages, no way to know what they actually mean. WHY EXISTING SOLUTIONS FAIL Most food trackers show you lists and numbers โ€” not a visual picture of what you ate. If you missed taking a photo, there's no way to add one after the fact. And none of them help you make sense of your health data. THE SOLUTION FoodDiary lays out your entire month of eating โ€” breakfast, lunch, and dinner โ€” on a familiar calendar. Forgot to take a photo? Apple Intelligence generates an image of your meal and estimates its nutrition โ€” even days later. Your health data, made meaningful. See how your numbers compare against averages for men and women, and copy a ready-made prompt into any AI for a plain-language breakdown of what it all means. Free use includes banner ads. Remove ads permanently with a one-time purchase. No subscription.

Verdict

The call

The clearest difference is in-app purchases: Food_Diary at none against Gym Log's 1. Food_Diary also leads on iOS requirement (18.0 vs 26.0). Gym Log's advantage is ads (none vs shown). On price, update cadence and device support there is nothing between them.
