Half the ideas have a solution or a WIP solution :

- first bullet point is litteraly what made Instagram back in 2010s

- calorie tracking is done by taking a picture

- Lifting coach : I 100% bet most lifting app teams are already on it

- Recommandation engine : there is probably 0 money to make here to link random web pages. Where there is money, it's already done brillantly (for the companies) : Tiktok, Youtube algorithms have made huge progress since I see a lot of comments by people saying "I don't know why YouTube recommanded me that video but I am glad I watched it", GOogle News, and probably many more.

- calorie tracking is done by taking a picture

- everything "minimalist" => any good tool focused on 1 main feature and get success will add more feature to cater to specific needs that current users have or that future users are thought to have.

I stop reading the list at that point :/
