# Korea Lens vs TOPIK Note

The clearest difference is rating: TOPIK Note at 4.9 against Korea Lens's 3.7. TOPIK Note also leads on update cadence (every 4 days vs fortnightly) and ratings volume (55 vs 3). Korea Lens's advantage is review sentiment (100% vs 65%) and ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Korea Lens sells 3 in-app purchases, starting at $9.99 per month and TOPIK Note sells 6 in-app purchases, starting at $10.99 per month. Whichever you choose, the download price is not the number that matters.

TOPIK Note holds the better App Store score, 4.9 against 3.7. That said, the two scores are not equally well evidenced: TOPIK Note has 55 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of Korea Lens's written reviews are positive against 65% of TOPIK Note's, so the app with the better star average is not the one people write more warmly about.

Korea Lens ships an update fortnightly, TOPIK Note every 4 days. Both last shipped on November 9, 2026.
