Verdict

The call

The clearest difference is rating: 2nd Line at 4.4 against ZenSim's 3.7. 2nd Line also leads on ratings volume (1.3K vs 3). ZenSim's advantage is in-app purchases (none vs 10) and review sentiment (80% vs 71%). On price, update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

2nd Line holds the better App Store score, 4.4 against 3.7. That said, the two scores are not equally well evidenced: 2nd Line has 1.3K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 71% of 2nd Line'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.

UpkeepUpdate frequency

2nd Line ships an update fortnightly, ZenSim every 3 weeks. Both last shipped on November 8, 2026.
