# VR Mobile vs Seismometer+

The clearest difference is ads: VR Mobile at none against Seismometer+'s shown. VR Mobile also leads on review sentiment (100% vs 67%) and rating (4.7 vs 4.5). Seismometer+'s advantage is ratings volume (82 vs 11). 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.

VR Mobile holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Seismometer+ has 82 ratings behind it against 11, so its average is the more settled of the two. Written reviews point the same way: 100% of VR Mobile's written reviews are positive against 67% of Seismometer+'s.
