Best Calorie Counter App Overall: Noom

If you are on a tight budget, FatSecret or Samsung Health give you solid tracking at zero cost. If intermittent fasting is your primary strategy, Zero remains the most polished of the fasting apps available. Most apps give you a static calorie number based on a formula. MacroFactor recalculates your targets weekly based on your actual weight trend data and food intake. If you are eating 2,200 calories a day and losing 0.3 pounds per week instead of your goal of 0.75 pounds per week, the app adjusts your target downward automatically. If traditional calorie counting feels oppressive, try Nutrola.

It is important that your chosen fasting app works smoothly with your phone, watch, and any other devices you rely on.
