# PetriPet 2 vs AlienSwarms

The clearest difference is ads: PetriPet 2 at none against AlienSwarms's shown. PetriPet 2 also leads on ratings volume (16 vs 1) and iOS requirement (13.0 vs 15.0). AlienSwarms's advantage is update cadence (every 2 weeks vs every 4 months) and monetization model (free vs free with in-app purchases). On price, in-app purchases and device support there is nothing between them.

Both are free to download. PetriPet 2 sells 4 one-off in-app purchases and AlienSwarms sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

AlienSwarms holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: PetriPet 2 has 16 ratings behind it against 1, so its average is the more settled of the two.

PetriPet 2 ships an update every 4 months, AlienSwarms every 2 weeks. The most recent releases landed on October 30, 2026 and October 9, 2026 respectively.
