Mealbase

Mealbase is an application for generating food suggestions about the meals you eat. Try it on heroku. Heroku free was cancelled and thus this app is no longer available there.

How it works

• The user logs the meals they eat.
  • All meals are comprised of ingredients. For each meal, the user inputs at least the main ingredients.
    • i.e. meatballs and spaghetti -> meat, pasta. Chicken soup -> chicken, potatoes.
• Based on the record of meals, mealbase tries to suggest foods that keep your menu diverse.
  • Recommendations are done based on ingredients and logging dates. Mealbase suggests ingredients based on the number of days since they have last been logged - the longer the time since last eaten, the higher the priority for suggesting.
  • The user can query the database for meals containing the suggested ingredients.
