# Solar Express vs Mars Perseverance 3D Simulator

The clearest difference is review sentiment: Mars Perseverance 3D Simulator at 59% against Solar Express's 0%. Mars Perseverance 3D Simulator also leads on ratings volume (178 vs 9). Solar Express's advantage is ads (none vs shown) and update cadence (weekly vs every 66 months). On price, in-app purchases and device support there is nothing between them.

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

Solar Express holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Mars Perseverance 3D Simulator has 178 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 0% of Solar Express's written reviews are positive against 59% of Mars Perseverance 3D Simulator's, so the app with the better star average is not the one people write more warmly about.

Solar Express ships an update weekly, Mars Perseverance 3D Simulator every 66 months. Both last shipped on November 3, 2026.
