dont think so, looks like some type of amanita however if you could post pics of the stipe and gills that helps. usually you want to decide from looking at a few different parts of the mushroom not just one
i wouldnt trust an APP EVER. if you learn to ID them by the things i mentioned above (stipe, gills, cap, habitat) and then make sure they are known to grow in the region you are looking in it can help you narrow it down. you really want to check every mushroom thoroughly before ever ingesting it. the APP could help you narrow things down but I would just learn to ID them proper on your own from the start!
edit: cant believe i forgot to mention you should also take spore prints where you leave a cap on tin foil or white paper overnight to see the color of the spores that drop out etc
