Want it? Wait for it.

Type what you want to buy or do, set a wait of up to 24 hours, and lock it in. A Live Activity countdown lives on your Lock Screen and Dynamic Island — a constant, honest reminder that you said you'd wait.

Most impulses don't survive 3 hours. The ones that do are probably worth it.

Pros & Cons

Weigh it properly.

Not all pros are equal. Assign low, medium, or high weight to each item and get a verdict — Lean yes, Lean no, or Balanced — backed by actual score. Save decisions as presets to reuse your frameworks.

Bracket Decider

Let the best option win.

Add up to 16 options and run a tournament-style bracket. Head-to-head matchups force honest comparisons — you can't stay on the fence. One option wins.
