How many people can I share my app with?
You are free to let other people use your device it to manage their own diet. However, it is what you previously ate as well as your user profile details (such as your height, weight, age and habits) that are used to determine the foods you can eat. Letting others log food will skew the recommendations that DietSensor gives to you regarding your nutrition, and also the advice they will get from the app. It is thus recommended not to share the use of your app with anyone if it is not to log the food you eat.
But several people can use the same Phone to create an account. You will have to disconnect and reconnect to the right account each time the user changes.
How many phones can I install DietSensor on?
Since your account information is stored on our cloud servers, you can install DietSensor on as many phones as you need. Remember however, that it is your own profile and historical food logs which will be shown on each phone. So modifying your profile on a phone will affect the information on all other phones.
