I have 4 credit cards and kept guessing wrong about which one was “safe” to use. The issue: I was only tracking current balance/utilization, not statement closing dates.
Your balance gets reported to credit bureaus when your statement closes — not when you pay. So even though I pay in full every month, I was spiking my utilization without realizing it.
I built WhichCard to fix that. It shows:
Available spend under 30% on each card
Days until each statement closes
Red / yellow / green indicators for quick decisions
Example:
Chase shows $450 available but closes in 3 days → Don’t use.
Capital One shows $890 available and just closed yesterday → Safe.

Timing turned out to matter more than I expected.
