Verdict

The call

The clearest difference is ads: Roblox at none against Idle Anomaly's shown. Roblox also leads on ratings volume (20M vs 364) and update cadence (weekly vs every 5 weeks). Idle Anomaly's advantage is rating (4.7 vs 4.5). On price, in-app purchases, monetization model and device support there is nothing between them.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Roblox sells 16 in-app purchases, starting at $4.99 per month and Idle Anomaly sells 15 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Idle Anomaly holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Roblox has 20M ratings behind it against 364, so its average is the more settled of the two. Written reviews complicate that: 60% of Roblox's written reviews are positive against 38% of Idle Anomaly's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Roblox ships an update weekly, Idle Anomaly every 5 weeks. The most recent releases landed on September 26, 2026 and September 16, 2026 respectively.
