Verdict
The clearest difference is rating: felix mobile at 4.4 against ZenSim's 3.7. felix mobile also leads on ratings volume (39 vs 3). ZenSim's advantage is review sentiment (80% vs 49%) and update cadence (fortnightly vs monthly). 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.
felix mobile holds the better App Store score, 4.4 against 3.7. That said, the two scores are not equally well evidenced: felix mobile has 39 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 49% of felix mobile's written reviews are positive against 80% of ZenSim's, so the app with the better star average is not the one people write more warmly about.
felix mobile ships an update monthly, ZenSim fortnightly. The most recent releases landed on September 23, 2026 and September 10, 2026 respectively.
