Sparrow Pulse tracks HYSA rates across 15+ banks, alerts you when your rate drops, and shows exactly how much more you could earn — in real dollars, not abstract percentages.
No credit card. Free forever.
We rank accounts beyond raw APY — stability, promo vs. non-promo, and fees all factor in. A 5.10% promo that drops in 3 months scores lower than a steady 4.85%.
"$127/year more" becomes "Netflix + Spotify every month." Concrete anchors help you actually act on the data.
Switching banks costs 3-5 days of lost interest during transfer. We calculate whether switching actually pays off, and exactly how fast.
When your rate drops, we tell you where you now rank nationally. "Down 25bps but still top 20%" is useful. "Rate dropped" is not.
See whether a bank's rate has been rising, falling, or stable before you open an account. Avoid banks heading in the wrong direction.
Track multiple savings accounts. See your blended effective APY and which account is dragging you down.
Tell us your bank and product. Add a balance for earnings estimates.
Rate changes are detected and logged. Your Rate Health Score updates automatically.
