# WBV vs Seismometer+

The clearest difference is review sentiment: Seismometer+ at 67% against WBV's 0%. Seismometer+ also leads on ratings volume (82 vs 1). WBV's advantage is rating (5.0 vs 4.5) and ads (none vs shown). 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.

WBV holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Seismometer+ has 82 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of WBV's written reviews are positive against 67% of Seismometer+'s, so the app with the better star average is not the one people write more warmly about.
