Best Pokemon app for me

This app is best Pokemon app for me and it has all Pokemon walkthroughs of Pokemon,but its not that nice because it doesnt show the backward evolution of Pokemon.For example if you see Venusaur evolutions it doesnt show bulbasaur and Ivysaur which are backward evolutions ????!
