About this app

Every purchase has a second price.

That $6 latte? Invested instead, it is worth hundreds over 30 years. That 11pm impulse buy? Thousands. CostMe shows you the number nobody else shows you: what your money becomes if you do not spend it.

HOW IT WORKS
1. Type any price and see its 30-year invested value instantly, with real market math you can check.
2. Feeling the urge? Park it in the 48-hour vault. Decide Thursday, not Tuesday-night-you.
3. Ask Amy, your AI money coach, for a calm second opinion before you tap buy.

WHY IT WORKS
CostMe is built on decades of behavioral finance research, not willpower lectures. Seeing a price as lost future wealth changes the decision. That is loss aversion, one of the most replicated findings in economics.

FEATURES
- True-cost calculator: any price becomes its invested value, math shown
- 48-hour impulse vault: pause the buy, keep the proof when you resist
- Amy, your AI money coach: talk through any purchase, 24/7
- Subscription tracker: every recurring charge in one place
- Lifetime savings tracking: watch what not-spending adds up to

Free to start. No ads inside the app. Your data is yours and is never sold.
