Long Time User. Simple and Reliable.
I've been using MyFitness Pal for years. It's simple and reliable. Once you've been using it this long so many of your common recipes are easy to access for revision and logging again. They make it difficult to switch to a competitor once they know your dietary habits as well as they know mine. The only thing I struggle with is importing recipes from online when there are too many pop ups/ distractions on the webpage.
