Apps

The apps we would use to count calories and keep a food diary, and why.

Seven apps, one question: which makes adding up a day of food quick enough that you actually keep doing it?

Breakfast, lunch, dinner and the snack in between: what each app asks of you at every meal, and which one makes a whole day painless.

What you get for nothing, for about $35 a year, and for $70-plus, and why one app wins at every price.

Losing, holding steady, building muscle or keeping an eye on blood sugar: the tracker that suits each goal, and the one that suits them all.

Forget the leaderboard of features. Here is which food diary answers the question you actually have about your eating.

Five food diaries, sized up on how you log, what they record and what they cost, with one clear first choice.
