# DAIG Bookshelf vs Mine Locator Map

The clearest difference is rating: Mine Locator Map at 4.6 against DAIG Bookshelf's 3.3. Mine Locator Map also leads on ratings volume (348 vs 7). DAIG Bookshelf's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, update cadence and device support there is nothing between them.

Both are free to download. Mine Locator Map sells 1 one-off in-app purchase. DAIG Bookshelf asks for nothing beyond the download.

Mine Locator Map holds the better App Store score, 4.6 against 3.3. That said, the two scores are not equally well evidenced: Mine Locator Map has 348 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 25% of DAIG Bookshelf's written reviews are positive against 13% of Mine Locator Map's, so the app with the better star average is not the one people write more warmly about.
