# SimlessPay vs KEEP by Fast FX

The clearest difference is ads: SimlessPay at none against KEEP by Fast FX's shown. SimlessPay also leads on monetization model (free vs free with in-app purchases) and ratings volume (28 vs 3). KEEP by Fast FX's advantage is rating (4.7 vs 4.5). 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.

KEEP by Fast FX holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: SimlessPay has 28 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 80% of SimlessPay'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.

Both ship on a similar rhythm, roughly every 10 days. The most recent releases landed on October 14, 2026 and October 7, 2026 respectively.
