# Line vs Porter

The clearest difference is review sentiment: Porter at 77% against Line's 33%. Porter also leads on rating (4.2 vs 3.4) and in-app purchases (none vs 1). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Line sells 1 one-off in-app purchase. Porter asks for nothing beyond the download.

Porter holds the better App Store score, 4.2 against 3.4. That said, the two scores are not equally well evidenced: Porter has 43 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 33% of Line's written reviews are positive against 77% of Porter's.

Line ships an update every 4 months, Porter fortnightly. The most recent releases landed on June 4, 2026 and August 21, 2026 respectively.
