What makes us different
Most apps track what you already spent.
We stop you before you do.
Think To Buy is the only app built around the moment that actually matters — the second before you open your wallet.
Only us
Pre-purchase, not post-purchase
Mint, YNAB, and Copilot all analyze money you've already spent. Think To Buy works before you buy — giving you a verdict while you can still say no.
Only us
No bank account required
Every competitor asks to link your bank. We never touch your accounts — just type in the numbers. Your financial data stays on your device.
Only us
Opportunity cost built in
We show you what that money becomes in 10 years if invested instead. Not just "you have $X left" — but what you're actually giving up.
Only us
Built for people without a salary
YNAB costs $99/year and assumes a full income. Think To Buy is free forever and works whether you make $50 a week or $5,000.

How your score is calculated
Smart Buy
Under 15% of savings and recoverable in under 3 weeks of income. You can comfortably afford it.
Think Twice
15–70% of savings or 3–6 weeks to recover. Possible, but worth pausing and planning first.
Don't Buy
Over 70% of savings or 6+ weeks to recover. This would leave your finances dangerously thin.

Pay yourself first
Move money to savings the moment you get paid — before spending anything. You can't miss what you never see.
Time beats timing
Starting to save early matters more than saving the "right" amount. Compound interest rewards patience above all else.
Emergency fund first
Before investing or big purchases, build 3–6 months of expenses as a buffer. It's the foundation everything else rests on.
Automate everything
Willpower is unreliable. Automatic transfers to savings and investment accounts remove the decision — and the temptation.
