Once you have linked your account with an App Gallery partner that measures your full day's calorie use, it's important that you log your food and exercise only with MyFitnessPal. We will sync your food and exercise diary information to the partner site for you. Logging food or exercise yourself on the partner website is unnecessary, and may lead to incorrect Net Calorie Goal adjustments.
Please note that if you are wearing a step-based tracker such as Fitbit, we recommend that you not manually log any exercise to your MyFitnessPal Exercise Diary that these devices excel at tracking: this includes walking, jogging, running, climbing stairs or hills, or daily home or office activity. These will be more accurately recorded by the device and will then transfer to MyFitnessPal as part of your Calorie Adjustment. We recommend that you manually log to MyFitnessPal any exercise that your step-based tracker's system will have trouble detecting accurately, such as rowing, cycling, and of course activities like swimming during which you cannot wear the device.
Please contact the manufacturer for the best guidance on the use of any particular App Gallery device.
