Verdict
The clearest difference is ads: Flux Link at none against Keepsmile's shown. Flux Link also leads on monetization model (free vs ad-supported). Keepsmile's advantage is update cadence (every 3 weeks vs every 24 months) and ratings volume (4.8K vs 6). On price, rating, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Flux Link holds the better App Store score, 2.7 against 2.5. That said, the two scores are not equally well evidenced: Keepsmile has 4.8K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 0% of Flux Link's written reviews are positive against 20% of Keepsmile's, so the app with the better star average is not the one people write more warmly about.
Flux Link ships an update every 24 months, Keepsmile every 3 weeks. The most recent releases landed on June 1, 2026 and October 1, 2026 respectively.
