Line App Poster Image




Social media, games, video, text, audio chat all in one app.

What parents need to know

Ease of play

Some users may find that Line seems more complicated than most messaging apps because of its multi-step registration process and the multitude of options for everything from adding friends (via message, quick response code, or "shaking" devices together, for example) to melding social media timelines with messaging options, games, and more. 


Violent content is against Line's terms of use. There's no violent content in the app itself, but teens can send and receive unmonitored texts, photos, voice messages, and videos. Messages can be given expiration times, similar to Snapchat.​


"Sexual expressions" are against Line's terms of use, but teens can send and receive unmonitored texts, photos, voice messages, and videos. Messages can be given expiration times, similar to Snapchat.


Some stickers include mild profanity or abbreviations for profanity.


Although Line is free, the app encourages users to purchase coins to buy stickers and screen themes, play games, and make calls to non-Line users. Official accounts are generally for brand, product, celebrity, or consumer media news and promotions.

Drinking, drugs, & smoking

Some stickers include images of characters drinking alcoholic beverages.

Parents Need to Know

Parents need to know that Line is a multifaceted text, video, and voice-messaging app that also includes social media elements, such as games, group chats, and personal timelines. Privacy can be improved by using the privacy settings, which include the option to make your "Public User ID" not public, add a passcode, and filter message from non-friends. The app is free, but in-app purchases are required for some features, such as calling contacts who aren't Line users and using most stickers, themes, and games. Users can add other users to their contacts through invites, QR code, or shaking their smartphones. Line includes an option to choose "Hidden Chat," which entirely deletes messages after a brief time, similar to Snapchat. Some Line accounts called "official" accounts (similar to verified accounts on other networks) are used to promote a brand, product, celebrity, or consumer media to other individual users. Line includes versions for many mobile-device platforms as well as desktop computers.

What's it about?

Register for LINE with your mobile device's phone number and an email address (or only an email address for computer or non-phone-based devices). Create a profile, and view which friends in your contacts already have LINE so you can call or message them for free. Invite other friends to Line, browse and add stickers, play games, or view official accounts for news and information. All features can be accessed from the app's main screen and a "more" tab. Line packs a lot of messaging and social media options into one app.

Is it any good?


Line has become a popular messaging app, presumably in part because of its many options for messaging, cute stickers, and use across platforms and computers. But that multitude of options may be a drawback, too. This app includes a lot of ways to spend money, little by little, through small in-app purchases for a pack of cute stickers or a game.

The integration between some social media elements (timelines, games) and video, audio, calls, and many other forms of messaging is interesting, although sometimes more options in one app are useful and at other times they can clutter basic functions until it becomes too distracting to enjoy any of the many options. Voice-message sound quality during this review was less clear than in other messaging apps. Sometimes simplicity can help users communicate even better than a multitude of methods, and LINE rides the thin line between enough and too many choices.

Families can talk about...

  • Review the privacy options on Line with your teens and encourage them to keep their user IDs private and filter messages from people they don't know.

  • Discuss your family's rules about in-app purchases with your teen.

  • Families can talk about messaging apps. Read Common Sense's trend alert about messaging apps and talk with your teen about why it's not a good idea to share iffy secrets online.

My daughter is only 9years old and has a tablet to play on for an hour a day. I found my daughter playing this app and people are messaging her about porn and sex and asking her to post pictures of her body!! This app should require a parental consent!!!

Pretty good

A couple of weeks ago, I downloaded Line because I was using Line Play and it was suggested to me in the App Store. It's a bit creative (on how you could replace words with images related to it) but it can get pretty confusing if one uses the images too much. It just strains your eyes, basically. Otherwise, I think it is pretty good; it's safe for kids, I think. My 11 year old sister is using it, and she likes it (she only has three friends: me and her two best friends at school) so I think it is best for about 11 to 12.
