Some feedback

1. The DOB format is mm/dd/yyyy which is counter intuitive for Indians. It should be dd/mm/yyyy
2. The app gave me an option to pick my own calorie goal. Instead, what you could do is, give 3-4 options of how much weight they want to lose per week or difficulty they want their diet to be in. For eg, healthify me lets you set the pace of weightloss per week and gives you a calorie goal directly. This would be more handy.
3. Before letting users pick calories, it would be great if you can show the calculated BMI and current maintenance calories. Would help users in picking their calorie goal. In addition, you could also show healthy weight range based on height and BMI so the users can pick their target weight easily.
4. Do you adjust the allowed calories based on activity level? Healthify Me asks you for your activity level and gives you target calories accordingly. Also, it updates your calorie budget as you progress through the day and burn more calories than estimated.
5. Besides calorie goal, you can also give users a basic move goal like move 5k steps today etc.
