Check List
Read full descriptionHide full description
Fewer "oops" moments. A checklist you can reset and reuse. "Did I lock the door?" "Did I turn off the AC?" "Did I finish my homework?" Ever gotten halfway down the street and had to turn back? For the things you do every day, stop trying to remember. Let a list do it. Check, reset, repeat. That's all it takes to stop the daily slip-ups. This isn't a to-do list that disappears when you're done. It's a checklist you can reset and use again and again. No account needed. WHEN IT HELPS - Before you head out: Wallet, phone, keys. Check your must-haves at a glance before you step outside. - Locking up: Window locks, the gas valve, the iron's plug. Check before you go, and stop worrying once you're out. - Trips and business travel: Packing is easy when you reuse a list you've already made. Done in minutes. - School and work: Check the night before, and start the day without forgetting a thing. KEY FEATURES - One-tap checking: Tap to check off items in just a few moments before you leave. - Completion stamp: Check everything and a big stamp appears, so you can see that you've covered it all. - Reset all: Clear every check with one button and get ready for the next day. - Easy editing: Swipe left to edit or delete, press and hold to reorder. - Multiple lists: Keep separate lists for work, home, travel and more. Pro (one-time in-app purchase) - Unlimited checklists and items - Import and export lists (for backups, moving to a new phone, or sharing) - No ads Start with three things you grab every morning. Tomorrow, "Did Iโฆ?" becomes "Checked."

Verdict
The clearest difference is in-app purchases: Sync at none against Check List's 1. Sync also leads on ads (none vs shown) and update cadence (every 6 weeks vs every 5 months). On price and device support there is nothing between them.
