Did I lock the door? Did I turn off the stove? Paranoid gives your before-you-go checks a place to live. Start with a home checklist, mark each item after you check it, and keep a dated record you can look back at. CHECK IT. MARK IT. MOVE ON. Create a short list for leaving home, going to bed or heading away for the weekend. Use the ready-made essentials or build your own list. Change any item to fit your home. SEE WHAT YOU CHECKED — AND WHEN Each checkmark has a time. Complete a list to save a record of its items and their timestamps in History. Previous checks keep their original dates. READY FOR THE NEXT TIME Start a new check whenever you need one. Your old completed checks stay in History, and Undo lets you reverse an accidental reset. MAKE IT YOURS Name your lists, add as many items as you need, and choose light or dark appearance. Travel Packs are also available for temporary trip lists; these expire after the duration you choose. USEFUL FROM THE START Free includes three regular lists, unlimited items, three home templates, check history and appearance options. MORE WITH PREMIUM A one-time purchase unlocks unlimited regular lists, extra templates for work, car, pet care and travel, saving your own templates, and optional reminders. No subscription. YOUR CHECKS. YOUR DEVICE. Your checklists and history are stored locally. No account is needed, and there are no ads. Paranoid records the actions you mark as checked. It does not monitor appliances, doors or your home. Check it. Mark it. Move on.

Verdict
The clearest difference is in-app purchases: Knack at none against Paranoid's 1. Knack also leads on iOS requirement (16.0 vs 18.0). Paranoid's advantage is update cadence (fortnightly vs every 2 months). On price, ads and device support there is nothing between them.
