Great way to track and be accountable

This app adjusts based on your needs. It has most of the foods I eat regularly. It is easy to add if necessary. The support is beyond appreciated. They are kind and friendly. The app is often getting updated to make it better. This is my third or fourth year with them, and I love it.

Have used for years

It’s my go to app but it can be a bit annoying at times. I hate how when I lose weight it automatically changes my calories. Give me control over my calorie budget. For example, I want it to stay 2300-2400 per day and then you automatically increase to 2600. It’s just annoying because I have to restart everything.

Measuring Required

The app offers very limited weight and measurement options when logging food, so plan to modify everything you eat and log to their tight parameters. Plan to cancel and find something more user friendly.

Best Food Tracking App

Extremely simple to use, especially with new upgrades. Food library quite large. Easy and quick to enter food. The fill in circles makes it convenient throughout the day to follow your plan. Love this app
