# SimDif vs Universe Website Builder

The clearest difference is ads: SimDif at none against Universe Website Builder's shown. SimDif also leads on review sentiment (81% vs 55%) and rating (4.7 vs 4.5). Universe Website Builder's advantage is update cadence (every 10 days vs monthly) and ratings volume (9.8K vs 1.6K). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. SimDif sells 15 in-app purchases, starting at $3.99 per month and Universe Website Builder sells 9 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

SimDif holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Universe Website Builder has 9.8K ratings behind it against 1.6K, so its average is the more settled of the two.
