My net diary, mynetdiary.com after doing audits on different apps, found it helpful. The user interface is very user-friendly. You can save recipes to it as well. The other she likes is Spoonful because you can save recipes here in categories as specific as for a fodmap diet which I need because I have an irritable GI system and have gas very easily. Noom is good for people that are motivated by community support but not her favorite.
