Lock In isn't another endless to-do list. It's a daily ritual: brain-dump everything on your mind, then lock in the three things that actually matter today. HOW IT WORKS Type anything β the page is yours, like a scratchpad you never have to organize. Your top three rise to the top as your Focus for the day. Tap the progress ring to open Today, check them off, and watch the ring close. Finish all three and you "lock in" β a moment that makes finishing feel earned. That's the whole app. No projects, no folders, no nagging backlog. Just today, and your three. WHY IT'S DIFFERENT β’ The top-3 ritual β you don't manage a hundred tasks, you commit to three and finish them β’ A brain-dump that stays raw β capture fast, organize never β’ The lock-in moment β a progress ring and a small celebration when your three are done β’ Make it yours β accent colors to match your vibe (Lock In Pro) β’ Private iCloud sync β your list follows you across devices, never our servers β’ Home-screen widget + a gentle daily nudge PRIVATE BY DESIGN No accounts. No analytics. No ads. Lock In collects nothing β your tasks stay on your device and in your private iCloud. Pick three. Lock in. Finish today.

Verdict
The clearest difference is in-app purchases: Lock In at none against PriorityStack's 1. Lock In also leads on ads (none vs shown). PriorityStack's advantage is iOS requirement (17.0 vs 26.0). On price and device support there is nothing between them.
