# Planet simulation vs Solar Smash 2D

The clearest difference is rating: Solar Smash 2D at 4.7 against Planet simulation's 3.9. Solar Smash 2D also leads on ratings volume (13K vs 164) and update cadence (every 3 months vs every 7 months). Planet simulation's advantage is in-app purchases (none vs 1) and iOS requirement (13.0 vs 15.0). On price, ads and device support there is nothing between them.

Both are free to download. Solar Smash 2D sells 1 one-off in-app purchase. Planet simulation asks for nothing beyond the download.

Solar Smash 2D holds the better App Store score, 4.7 against 3.9. That said, the two scores are not equally well evidenced: Solar Smash 2D has 13K ratings behind it against 164, so its average is the more settled of the two. Written reviews point the same way: 74% of Planet simulation's written reviews are positive against 83% of Solar Smash 2D's.
