Check It Again is a dead simple checklist app for the things you do over and over. Pack your bag. Prep for a meeting. Run your weekly review. Check everything off. Do it all again next time. That's it. That's the app. No AI. No subscription. No "premium features." No tracking what you check off or selling that data to anyone. No account to create. No onboarding flow. No push notifications asking you to "stay on track." No gamification. No streaks. No badges. No syncing your grocery list to a server farm in another country so an algorithm can learn your shopping habits. Just a list. With checkboxes. That you can use again. Check Again syncs privately across all your Apple devices via iCloud — your data stays yours, on your devices, period. If you've ever downloaded a checklist app and thought "why is this so complicated?" — this one's for you. Made with love in Westfield, Massachusetts (by just one guy).
