# The Stack System vs deWiz Golf

The clearest difference is review sentiment: The Stack System at 87% against deWiz Golf's 33%. The Stack System also leads on rating (4.9 vs 2.7) and monetization model (freemium vs subscription). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. The Stack System sells 6 in-app purchases, starting at $9.99 per 7 days and deWiz Golf sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

The Stack System holds the better App Store score, 4.9 against 2.7. That said, the two scores are not equally well evidenced: The Stack System has 7K ratings behind it against 11, so its average is the more settled of the two. Written reviews point the same way: 87% of The Stack System's written reviews are positive against 33% of deWiz Golf's.
