Most Dota drafting apps make you type hero names one by one while the pick timer runs down. Dota Addiction reads the entire draft through your camera in one look: point your phone at the screen and you get ranked counter picks and per-position item builds in seconds. The part I haven't seen elsewhere: link your Dota profile and the app tracks whether our picks actually won you games. Advice that grades itself. No account, no login. Recognition is server-side, so it improves with no update.
