I've never used a specifically low carb one - I've sometimes used our low carb recipes section here, found suitable recipes by searching elsewhere online .or simply adapted many of my normal recipes by cutting out the high carb ingredients.
Diet Doctor (which is much more informative now than it used to be), has a great selection recipes, and I also find since I shop with them that many of the recipes on Ocado are good starting points - often as they stand, or sometimes with just a little tweaking.
But low carb food needn't be either difficult or complicated, there are all sorts of simple, healthy meals which don't actually need a recipe, that you can make with some meat, poultry or fish, low carb veggies, a dollop of butter or oil for cooking them with, and a few herbs or spices if you want to liven things up a bit.
