Verdict

The call

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.

CostPrice · In-app purchases · Ads · Monetization

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.
