Verdict
The clearest difference is review sentiment: 対多 at 86% against LINE's 24%. 対多 also leads on rating (5.0 vs 3.2). LINE's advantage is ratings volume (19K vs 24) and chart position (#44 vs unranked). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. LINE sells 13 in-app purchases, starting at $3.99 per month and 対多 sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
対多 holds the better App Store score, 5.0 against 3.2. That said, the two scores are not equally well evidenced: LINE has 19K ratings behind it against 24, so its average is the more settled of the two. Written reviews point the same way: 24% of LINE's written reviews are positive against 86% of 対多's.
LINE ships an update every 9 days, 対多 weekly. The most recent releases landed on October 31, 2026 and October 25, 2026 respectively.
