Verdict
The clearest difference is price: LibreLinkUp at Free against Bone Age's $7.99. LibreLinkUp also leads on rating (4.8 vs 2.3) and ratings volume (23K vs 3). Bone Age's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.0). On review sentiment, update cadence, ads and in-app purchases there is nothing between them.
