# BadukPop Go vs One By One

The clearest difference is ads: BadukPop Go at none against One By One's shown. BadukPop Go also leads on ratings volume (7.1K vs 77). One By One's advantage is update cadence (every 2 weeks vs every 2 months) and review sentiment (91% vs 77%). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. BadukPop Go sells 7 in-app purchases, starting at $6.99 per month and One By One sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for BadukPop Go against 4.8 for One By One. That said, the two scores are not equally well evidenced: BadukPop Go has 7.1K ratings behind it against 77, so its average is the more settled of the two. Written reviews are what separate them: 77% of BadukPop Go's written reviews are positive against 91% of One By One's.

BadukPop Go ships an update every 2 months, One By One every 2 weeks. Both last shipped on November 3, 2026.
