LINE iOS App Review: Comprehensive Analysis of Features and Performance

by LINE Corporation

LINE offers free messaging, HD voice/video calls, and extensive sticker marketplace across mobile and desktop platforms. Primarily serves international communicators seeking expressive digital communication tools with additional entertainment integrations.

Detailed Review

LINE positions itself as a comprehensive communication platform that transcends basic messaging through its integration of entertainment services and expressive tools. The app functions as both a practical communication solution and a digital lifestyle platform, particularly popular in Asian markets but available globally across iOS, Android, desktop, and wearable devices. The core functionality includes text messaging, high-definition voice calls, and stable video calling capabilities that perform well across international connections. Beyond basic communication, LINE distinguishes itself through an extensive marketplace offering thousands of licensed and user-created stickers, themes, and exclusive content from LINE's sister services including webtoons and games. The platform supports group chats with up to 500 participants and maintains message synchronization across all linked devices. User experience varies by region, with the interface presenting a clean design that organizes features into distinct tabs for chats, calls, timeline, and additional services. Performance testing indicates reliable message delivery and call quality, though some users report connectivity issues in certain regions. The app integrates with iOS features including Share Sheet, Siri shortcuts, and Apple Watch compatibility, though some advanced features like desktop-style translation tools remain unavailable on mobile versions. User feedback reflects generally positive experiences with specific functional praises and criticisms. Ram21503 (June 23, 2025) appreciates the 'private messages, group chats, and free phone calls' alongside content purchasing options. CJ44444 (June 6, 2025) notes the disparity between mobile and desktop translation capabilities, requesting feature parity. Some users report persistent 'reading' status indicators and regional access concerns, as mentioned by _U-w-U_ (June 16, 2025), suggesting possible connectivity or censorship issues in specific markets. The app demonstrates strengths in multimedia communication and content ecosystem integration, though faces limitations in feature consistency across platforms and regional accessibility. LINE serves most effectively as a primary communication tool for users with international contacts, particularly those valuing expressive communication through stickers and integrated entertainment content, while users requiring consistent cross-platform feature parity may encounter frustrations.

Firstly first, All the things are nice. However the only thing that needs to be improved is “TRANSLATION”. Because it is incredibly inconvenient to chat with foreigns if this app doesn’t have the “TRANSLATION FUNCTION” or “AUTOMATICALLY TRANSLATION MESSAGES”!!! And this is the only issue that I want to report. Others are awesome. Nice nice!!! Good but need improvement Firstly first, All the things are nice.

I really wish more people used this app for messaging. It’s so much more fun than Discord with the various themes, stickers, and avatars. The fact that creators can make their OWN themes and stickers. All of the collaborations with our favorite brands and people (Disney, Nickelodeon, Sanrio, Pokemon, Snoopy, Garfield, Nintendo, Square Enix, HYBE, JYP, SM, YG, the list goes on and on). No need to pay a monthly fee for premium features. The attachment size limit is already much larger, and you can save the attachments and messages in your own albums. There’s even a feature where you can [capture] a conversation with an option to anonymize the names and profile pictures if you want to share a conversation. I cannot praise LINE enough. In response to the bad reviews: I truly don’t understand the bad reviews. I have been using LINE for nearly a decade now and I haven’t had a single issue. Ever. I’ve never heard of anyone getting banned, and I’ve never had to contact customer service for anything. The only situation I’ve ever experienced with logging in is because when you’re logged in on more than one device, the device that is used less will periodically log you out for security reasons, but all you do is just log back in, and it’s extremely easy. With my main device, I’ve never been forced to log out for anything. I did uninstall and reinstall once during the last 10 years, and again, I had zero issues with it. The app even kept all of my data. My only guess is that people are not wanting to use their phone numbers as a means to log in; I hate to break it to y’all, but this is the way East Asian chat apps work. They use your phone number. It’s not a big deal. My favorite chat app I really wish more people used this app for messaging. It’s so much more fun than Discord with the various themes, stickers, and avatars.
