# LINE vs Kaigyo

The clearest difference is review sentiment: Kaigyo at 100% against LINE's 14%. Kaigyo also leads on rating (4.9 vs 3.2). LINE's advantage is ratings volume (18K vs 203) and update cadence (every 9 days vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. LINE sells 13 in-app purchases, starting at $3.99 per month and Kaigyo sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Kaigyo holds the better App Store score, 4.9 against 3.2. That said, the two scores are not equally well evidenced: LINE has 18K ratings behind it against 203, so its average is the more settled of the two. Written reviews point the same way: 14% of LINE's written reviews are positive against 100% of Kaigyo's.

LINE ships an update every 9 days, Kaigyo monthly. The most recent releases landed on October 15, 2026 and October 6, 2026 respectively.
