Verdict
The clearest difference is ads: Zombie Infinity at none against Retro's shown. Zombie Infinity also leads on ratings volume (128 vs 5) and iOS requirement (13.0 vs 15.0). Retro's advantage is rating (5.0 vs 4.7) and review sentiment (100% vs 83%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Zombie Infinity sells 21 one-off in-app purchases and Retro sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Retro holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Zombie Infinity has 128 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 83% of Zombie Infinity's written reviews are positive against 100% of Retro's.
Zombie Infinity ships an update every 11 days, Retro every 5 days. The most recent releases landed on October 24, 2026 and October 11, 2026 respectively.
