CreditRun

You're at checkout. Which card do you use? Chase gives you 12 credit-free days. Amex gives you 38. Your Citi card might give you 51. CreditRun lives in the 3 seconds before you swipe - the moment that decides whether your money works for you or for the bank. Not an expense tracker. Not a budgeting app. CreditRun answers one question, fast: which card in your wallet gives you the most Credit Free Days right now? WHAT ARE CREDIT FREE DAYS? Credit Free Days is how long your money stays in your account after the purchase, before the bill is due. The longer the runway, the longer your money keeps earning. Every card calculates this differently based on its statement cycle, and the answer changes every single day. CreditRun does the math live, ranks your wallet, and tells you which card to swipe before the checkout countdown runs out. WHAT IT DOES • Add your cards in seconds. Issuer, last 4, credit limit, statement day, due day. That's it. • Live ranking. Every card scored by Credit Free Days, recomputed the moment you open the app. • One number per card. The one that matters today. • Tap a card to see exactly when its bill is due and how much float you'd lose if you swiped the wrong one. • Translate Credit Free Days into the cash value of that float, using a yield rate you set. • Track transactions so utilization, runway, and outstanding update automatically. • Insights that don't lie - months, quarters, all-time - to see how your wallet is actually performing. • CSV export and import. Your data, your file, anywhere you want it. • iCloud sync across iPhone, iPad, and Mac through your own Apple ID. DESIGNED TO BE FAST Open. Decide. Swipe. Close. Under 5 seconds.
