Verdict
The clearest difference is rating: Fitdays+ at 4.4 against TrackFit's 2.4. Fitdays+ also leads on update cadence (every 3 weeks vs every 5 months) and ratings volume (839 vs 96). TrackFit's advantage is review sentiment (26% vs 16%) and iOS requirement (11.0 vs 15.0). On price, ads, in-app purchases and monetization model 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.
Fitdays+ holds the better App Store score, 4.4 against 2.4. That said, the two scores are not equally well evidenced: Fitdays+ has 839 ratings behind it against 96, so its average is the more settled of the two. Written reviews complicate that: 26% of TrackFit'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.
TrackFit ships an update every 5 months, Fitdays+ every 3 weeks. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
