The plant app I use [0] gives a percentage confidence rather than saying "this is definitely X or Y". I've found it pretty accurate on the various plants and trees I've used it to ID. But I limit my foraging to nuts and berries I already know and generally only use the app to increase my recognition factor of what else grows around me.

I do like mushrooms but I think it's just a step too far into 'Russian Roulette' territory to risk trying to forage for those. Eating something which might make you sick for a day or two is one thing. But risking eating something which might kill you or require a liver transplant, if you get it wrong, is a bit too scary for me. The only mushroom I'm confident in my ability to ID is psilocybin.
