Shoo!
Locks any Mac app behind Touch ID, so it doesn't even render before you unlock it.
Shoo! locks individual Mac apps — Messages, Mail, a banking app — behind Touch ID, Apple Watch, or a backup password, and the app simply never renders on screen until you unlock it. That's different from typical lockers, which only check once at launch or cover the screen with an overlay you can sometimes peek behind; Shoo! re-checks every time you switch back and asks for no system permissions. It's a one-time $17.99 after a 7-day full-feature trial, with no subscription, no analytics, and offline operation apart from update checks and license activation.
