Newbie help

Hi! New to keto and trying to get a hang of things with the diet and app. I'm three days in and 5lbs down. Gotta love that water wt. I got my perfect keto urine strips in today and after dinner read at 4.0 mmol/l. Was wondering if there was a way to change the app setting for the ketone input from mg/dl to mmol/l  that I'm missing. If not I'm just converting by multiplying my mmol/l by 18 right? Meal planning is going a little rough as the meal planner option puts me significantly over my goals (14g carbs, 82g fat, 67g protein 1061 cals) and when I adjust the serving amt to make it work like it says, I'm hardly eating any of it. If anyone has any tips on how to make it work or where to get the best recipes I'd appreciate it. I do better with some kind of structure like a meal plan or I'm mad scrambling at the end of the day trying to make my numbers haha
