# WITMOTION vs Seismometer+

The clearest difference is rating: Seismometer+ at 4.5 against WITMOTION's 3.0. Seismometer+ also leads on review sentiment (67% vs 38%) and ratings volume (82 vs 10). WITMOTION's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, in-app purchases, device support and iOS requirement there is nothing between them.

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

Seismometer+ holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: Seismometer+ has 82 ratings behind it against 10, so its average is the more settled of the two. Written reviews point the same way: 38% of WITMOTION's written reviews are positive against 67% of Seismometer+'s.
