Verdict

The call

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.

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
