# WeightWatchers Program vs Keto Diet App － Carb Tracker

The clearest difference is ads: Keto Diet App － Carb Tracker at none against WeightWatchers Program's shown. WeightWatchers Program's advantage is review sentiment (96% vs 68%) and ratings volume (2.4M vs 82K). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. WeightWatchers Program sells 7 in-app purchases, starting at $19.99 per month and Keto Diet App － Carb Tracker sells 7 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

WeightWatchers Program holds the better App Store score, 4.8 against 4.7. That said, the two scores are not equally well evidenced: WeightWatchers Program has 2.4M ratings behind it against 82K, so its average is the more settled of the two. Written reviews point the same way: 96% of WeightWatchers Program's written reviews are positive against 68% of Keto Diet App － Carb Tracker's.
