# Let's 일빵빵 vs 암기고래

The clearest difference is rating: Let's 일빵빵 at 5.0 against 암기고래's 4.7. Let's 일빵빵 also leads on iOS requirement (13.0 vs 16.0). 암기고래's advantage is update cadence (every 2 weeks vs monthly) and ratings volume (86 vs 15). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Let's 일빵빵 sells 4 in-app purchases, starting at $16.99 per month and 암기고래 sells 12 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Let's 일빵빵 holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: 암기고래 has 86 ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 81% of Let's 일빵빵's written reviews are positive against 88% of 암기고래's, so the app with the better star average is not the one people write more warmly about.

Let's 일빵빵 ships an update monthly, 암기고래 every 2 weeks. The most recent releases landed on October 17, 2026 and October 16, 2026 respectively.
