Ideas for a better calorie counting app.

Hello,

for the past few weeks I have been developing a calorie counting app using AI like ChatGPT and some free food apis for searching food and barcode scanning. I've also added a fasting tracker and a simple onboarding but other than that I am not so sure what would people in an app like this want, so I have a few questions that woudl really help me to make the app better. The app is live but I won't share the link because I don't want to look like self promoting.

1. What are your desired features in a calorie counter app? (I can do pretty much anything with AI, so dont hold your imagination. :))
2. What is not needed in a calorie counter?
3. How much would you pay for such an app, the lowest, the highest and say which country you are from. (state price for subscription and lifetime offers.)
4. What should I track about food? So far, it only tracks macros, vitamins, minerals, ingredients and allergens.
5. How can AI be used to make the app better? What would capture your attention and make you use & pay for the app?
6. How much customisation do you prefer, tabs, colors, widgets, is this important for you?
7. How would you market the app? What feature would make the app desirable and unique?
8. Is integrating with other apps like huawei health, apple healthkit and google fit app important for you and which are most desirable?
9. What should appear in the onboarding?
10. Are achievements, gamification and notifications important to keep you using the app?
11. What would you want to see in stats? How much versatile should the stats be and give an example?
12. Should the app give information on how stay consistent and what are some vitamins for or how to fast and its stages?
13. Do you want to track anything you want like different extracts and so on.

And anything you think will be useful to know, I know that it is a saturated market but I believe I can push through which will obviously mean a greater reward and help people on the way ofc.

Please share what is your go to strategy for marketing and getting users. Mine was organic because I made apps in less saturated places but now my growth has been steadily going down, so I am trying something more competitive and so far tiktok and meta ads but they are not performing that well.
