Verdict
The clearest difference is review sentiment: ZenSim at 80% against My Optus's 22%. My Optus's advantage is rating (4.5 vs 3.7) and ratings volume (1.1K vs 3). On price, update cadence, ads and in-app purchases 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.
My Optus holds the better App Store score, 4.5 against 3.7. That said, the two scores are not equally well evidenced: My Optus has 1.1K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 22% of My Optus'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.
My Optus ships an update every 3 weeks, ZenSim fortnightly. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
