Excellent app to track calorie
sureshbans
I have found it extremely easy and helpful app to track my calories and maintain a healthy diet. I would recommend if it can add more suggestions or warning if any category consumption is not in permissible limit.
Quite nice, can improve Indian foods database
J. Parte
Thanks to the detailed nutrients breakdown, this app helps you not only track calories and macronutrients (proteins, fats and carbs), but also essential micronutrients — the vitamins and minerals.I just wish the database had more of the common Indian recipes listed. Often, I must add ingredients separately. Some recipes are available as branded, packaged food. But homemade recipes are missing!Also 2 suggestions for the developer — a) Would be great if existing ingredients can be searched by their Indian names. e.g. Pigeon pea lentils -> Toor dal.d) When using the search function, regional recipes should show first. Currently the first match for “Dal” — an Indian food staple — is a listing from “Dal Salumiere”, apparently a brand in Ireland.

Hey there!Thank you very much for the feedback, I have forwarded it onto the team, we do want to expand our database and we have been - our Curation Team adds thousands of foods every single week. We only hope to improve it in the future :)Have a great day and thanks again!
Reminder and water tracker is missing
avneetsng
Add a feature to add multiple reminders to track food. I would prefer to add different reminders for breakfast, lunch and dinner or snacks. One thing that make this app complete is an section for tracking water and to set goal for water consumption per day. And a reminder that reminds randomly thought-out the day to drink water to complete the target
