# aa 2 vs Octopus Evolution

The clearest difference is review sentiment: Octopus Evolution at 93% against aa 2's 41%. Octopus Evolution also leads on rating (4.8 vs 3.5) and ratings volume (4.1K vs 624). aa 2's advantage is ads (none vs shown) and update cadence (fortnightly vs every 6 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. aa 2 sells 2 one-off in-app purchases and Octopus Evolution sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Octopus Evolution holds the better App Store score, 4.8 against 3.5. That said, the two scores are not equally well evidenced: Octopus Evolution has 4.1K ratings behind it against 624, so its average is the more settled of the two. Written reviews point the same way: 41% of aa 2's written reviews are positive against 93% of Octopus Evolution's.

aa 2 ships an update fortnightly, Octopus Evolution every 6 weeks. The most recent releases landed on September 20, 2026 and September 16, 2026 respectively.
