# AiLink vs Fitdays+

The clearest difference is rating: Fitdays+ at 4.4 against AiLink's 3.2. Fitdays+ also leads on ratings volume (839 vs 51). AiLink's advantage is review sentiment (38% vs 16%) and update cadence (every 10 days vs every 3 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Fitdays+ holds the better App Store score, 4.4 against 3.2. That said, the two scores are not equally well evidenced: Fitdays+ has 839 ratings behind it against 51, so its average is the more settled of the two. Written reviews complicate that: 38% of AiLink's written reviews are positive against 16% of Fitdays+'s, so the app with the better star average is not the one people write more warmly about.

AiLink ships an update every 10 days, Fitdays+ every 3 weeks. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
