Verdict
The clearest difference is ads: Roblox at none against Alien Survivors's shown. Roblox also leads on review sentiment (60% vs 28%) and ratings volume (20M vs 134). Alien Survivors's advantage is iOS requirement (11.0 vs 14.0). On price, rating, in-app purchases and monetization model 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
Both are free to download. Roblox sells 16 in-app purchases, starting at $4.99 per month and Alien Survivors sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.5 for Roblox against 4.5 for Alien Survivors. That said, the two scores are not equally well evidenced: Roblox has 20M ratings behind it against 134, so its average is the more settled of the two. Written reviews are what separate them: 60% of Roblox's written reviews are positive against 28% of Alien Survivors's.
Roblox ships an update weekly, Alien Survivors monthly. The most recent releases landed on September 26, 2026 and September 3, 2026 respectively.
