# Roblox vs iBuilder

The clearest difference is review sentiment: Roblox at 60% against iBuilder's 16%. Roblox also leads on rating (4.5 vs 2.2) and update cadence (weekly vs every 29 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Roblox sells 16 in-app purchases, starting at $4.99 per month and iBuilder sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Roblox holds the better App Store score, 4.5 against 2.2. That said, the two scores are not equally well evidenced: Roblox has 20M ratings behind it against 12, so its average is the more settled of the two. Written reviews point the same way: 60% of Roblox's written reviews are positive against 16% of iBuilder's.

Roblox ships an update weekly, iBuilder every 29 months. The most recent releases landed on September 25, 2026 and June 11, 2026 respectively.
