# Starling vs KEEP by Fast FX

The clearest difference is ads: Starling at none against KEEP by Fast FX's shown. Starling also leads on monetization model (free vs free with in-app purchases) and ratings volume (2.8K vs 3). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Starling holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Starling has 2.8K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 74% of Starling's written reviews are positive against 77% of KEEP by Fast FX's, so the app with the better star average is not the one people write more warmly about.

Starling ships an update weekly, KEEP by Fast FX every 10 days. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
