# Weight Chart vs Weight Diary

The clearest difference is review sentiment: Weight Diary at 97% against Weight Chart's 29%. Weight Diary also leads on rating (4.9 vs 1.0) and ratings volume (2.6K vs 1). Weight Chart's advantage is price ($0.99 vs $7.99) and iOS requirement (12.0 vs 18.0). On update cadence, ads, in-app purchases and device support there is nothing between them.

Weight Chart costs $0.99 and Weight Diary $7.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Weight Diary holds the better App Store score, 4.9 against 1.0. That said, the two scores are not equally well evidenced: Weight Diary has 2.6K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 29% of Weight Chart's written reviews are positive against 97% of Weight Diary's.
