None right now, as I haven't tried them. I posted this problem to understand if there is need gap in the existing meal tracking apps, especially when used by those suffering from Autoimmune Disorders; Off the bat one thing I notice is that these apps are focussed towards weight reduction where as someone with AD would primarily want meal trackers to mark the food which works and which doesn't in terms of effects after each meal(Referenced HN thread in the problem statement has several accounts of it).

As a general user, I would check these out and if there's anything lacking I would comment. I would ask anyone with AD visiting this thread to add your valuable insight as well.
