How Miles works

Ask a question — which card to use, whether to transfer, what to keep or cancel. Miles works it out from your wallet against a curated rewards database and shows the math. Your Card Snapshot keeps the whole picture at a glance.

Which card, with the math shown

Ask which card to use for any purchase — the everyday entry point. Miles analyzes 186 cards, cross-checks rules and bonus categories, and shows the math behind the best move.

Your Card Snapshot

A personalized summary of your credit cards — credits, perks, earning rates, and transfer partners — based on the latest program data. No spending data required.

Keep-or-cancel verdicts

Is a card worth its fee? Miles weighs credits, anniversary value, and your spend, then shows the arithmetic — grounded in trusted sources like Frequent Miler and Doctor of Credit, not hallucinated tips.

Your next card, compared

Get personalized card suggestions based on your spending patterns, with sign-up bonus rankings and first-year value estimates. Plus keep-or-cancel analysis, eligibility tracking, and upgrade paths.
