Verdict
The clearest difference is update cadence: 1 Line Connect at every 2 months against One's every 26 months. One's advantage is ratings volume (402 vs 7) and rating (4.7 vs 4.4). On price, review sentiment, 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. 1 Line Connect sells 7 one-off in-app purchases and One sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
One holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: One has 402 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 92% of 1 Line Connect's written reviews are positive against 89% of One's, so the app with the better star average is not the one people write more warmly about.
1 Line Connect ships an update every 2 months, One every 26 months. The most recent releases landed on September 29, 2026 and October 20, 2026 respectively.
