1. Calorie Counter and Diet Tracker by MyFitnessPal

There are plenty of calorie-tracking apps out there, but MyFitnessPal is the most popular for a reason. Its database is colossal, containing over five million foods, meaning the frustration of being unable to log the exact item you’ve eaten is a rare event, rather than the norm.

2. VNutrition

Even if you have absolutely zero dietary restrictions it takes some planning to make sure you’re eating all the nutrients that your body requires, so it’s vital that you pay even closer attention if you make the decision to go vegan – whether that’s just for Veganuary or for good. The Vegan Society has created the VNutrition app to help people get from plant-based food what that they would previously have consumed by eating animal products. The advice is from a registered dietitian so it’s trustworthy, and there’s a simple checklist in the app to help you track how close you are to hitting your daily nutritional targets.
