Sample Size Calculator vs ChecklistApp

The Sample Size Calculator is a free tool to assist you to calculate Sample Size. You can input your own parameters like design effect, response rate, etc. All the parameters are set by default, but you have the ability to modify them. This application applies general statistical formulas.

A checklist is not a to-do list. Nothing here gets done and disappears: a checklist is the same list every time, and you run it again and again. ChecklistApp keeps your recurring lists — packing, camera bag, pre-flight, closing up the shop, groceries — and nothing else: • Tap + to create a list, then type its items. They keep the order you give them. • Run it: check things off as you go. Tap ↺ to reset for the next round. Nothing is ever lost. • Some lists have optional items. Flip the switch and every row gets a pass button for things you skip this round; Reset then floats what you checked to the top, in the order you checked it, so the list settles into the order you actually work through it. • Drag to reorder, swipe to delete, tap a name to rename. Free for two checklists. A one-time purchase unlocks unlimited lists — no subscription, no account. No accounts. No ads. No tracking. No due dates, reminders, folders, or AI. Your lists never leave your phone.
