# Koyfin vs StopLossTracker

The clearest difference is ratings volume: Koyfin at 1.4K against StopLossTracker's 2. Koyfin also leads on chart position (#145 vs unranked). StopLossTracker's advantage is review sentiment (100% vs 76%) and iOS requirement (15.1 vs 17.6). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Koyfin sells 4 in-app purchases, starting at $30.00 per month and StopLossTracker sells 8 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Koyfin against 5.0 for StopLossTracker. That said, the two scores are not equally well evidenced: Koyfin has 1.4K ratings behind it against 2, so its average is the more settled of the two. Written reviews are what separate them: 76% of Koyfin's written reviews are positive against 100% of StopLossTracker's.

Koyfin ships an update monthly, StopLossTracker every 2 months. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
