# Biology Dictionary vs Physics

The clearest difference is review sentiment: Physics at 100% against Biology Dictionary's 0%. Physics also leads on rating (4.7 vs 1.0) and ratings volume (20 vs 1). Biology Dictionary's advantage is in-app purchases (none vs 4) and device support (3 vs 1). On price and ads there is nothing between them.

Both are free to download. Physics sells 4 in-app purchases, starting at $1.99 per month. Biology Dictionary asks for nothing beyond the download.

Physics holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: Physics has 20 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 0% of Biology Dictionary's written reviews are positive against 100% of Physics's.
