calorie tracking app that won't let me lie to myself

Tried mfp, loseit, cronometer, all of them. same problem every time — I guess the portion, pick the leanest version from the dropdown, and the app just accepts it. end of the day everything's "within goal" and I'm not losing weight. want an app where I snap a photo of the meal and it gives me a realistic estimate, no way to game the input. bonus points if it pulls from apple watch without inflating burn the way apple does by default. happy to pay if it actually works.
