Type what you need, get a list
Describe it in a few words, like “leaving for Đà Lạt” or “power off before Tet”, and AI drafts a list for you to edit. Or start from one of the ready-made starter lists.
Checklists for things you tend to forget
The list you check before your brain says “wait…”
Keep small, repeatable checklists for switching things off, paying the bills, packing and the weekly shop. Check It Twice reminds you at the right time, lets you tick each item with a photo as proof, and keeps a history so you know it’s done.
Free to use. Works offline, with or without an account.
Fast to start, easy to trust, reminds without nagging
A list is one typed phrase or one starter list away. Only a name is required.
Reminders that know when to stay quiet
Set a time for a routine, a bill or a trip. You only get a reminder when a list still has something left to tick.
Tick it, with proof if you like
One tap ticks an item. Add a photo of the unplugged iron or the bank receipt, so “did I…?” has an answer.
Reuse it, round after round
Finish a round and the list clears for next time. Every past round stays in History with its ticks and photos.
Star the lists you use most
Starred lists sit on Home, ready for the next trip out the door.
