Popular Asian messaging app with free voice and video calls, stickers, and rich social features.

Overview

LINE's listing covers an unusual amount of ground, and the part worth reading first is not the chat but the endpoints: it says the service runs on mobile, desktop and Wear OS, a wider set of surfaces than most messaging apps here offer. The opening is the familiar one — closing the distance between family, friends and loved ones, for free — and behind it sit calls, messages, stickers, and two features most listings in this category do not have at all: a personal storage chatroom and a named encryption layer.

How it works

You message and call your LINE friends, one to one or in groups, and the listing organises everything else around that: stickers, emojis and themes to customise the app, a Home tab holding your friends list, birthdays and the sticker shop, Keep Memo, described as your own chatroom for temporarily storing messages, photos and videos, and a smartwatch path on Wear OS that shows messages and adds a complication to the watch face. Keep Memo is the interesting one, because it is a note-to-self built out of the chat primitive — and "temporarily" is the listing's own word, which is the one to remember if you were going to keep anything there you would miss.

Free vs paid

The listing says calls are free and then footnotes its own asterisk: it recommends a data plan or Wi-Fi, because you may incur data usage fees otherwise. That is the honest version of the free claim — the app costs nothing and the connection does not. What it does not do is state a price for anything it sells: it names a sticker shop and themes as features and never says whether either costs money, so a reader learns that commerce exists and not what it costs.

Safety and moderation

LINE names its protection, which most listings here do not: Letter Sealing, which the listing says encrypts messages, call history and location information. Two things about that sentence are worth holding onto. The first is that the list is specific — messages, call history, location — and a specific list should not be read as "everything". The second is that the listing does not say whether Letter Sealing is on by default or a setting you enable, and those are different products. The listing also describes no age requirement, no moderation process and no reporting route.

Who it's for

People who want messaging and calls with people they already know, across more devices than a phone — the Wear OS and desktop support is the differentiator, and Keep Memo is genuinely useful. For video calling specifically the listing says the least of any platform here: it names the feature and never describes it, so there is no group size, no quality claim and nothing to compare.

Verdict

A messaging app whose listing is unusually forthcoming about two specific things — where it runs and what it encrypts — and silent on the two a buyer would actually ask about, price and whether that encryption is switched on. The multi-device support and Keep Memo are real, and the free claim is honestly footnoted. Take Letter Sealing as a named feature with an unstated default, and check the setting rather than assuming the sentence covers you.

Frequently asked questions

Is LINE free?

The app is — the listing says calls are free and footnotes it by recommending a data plan or Wi-Fi, because you may incur data usage fees otherwise. It does not state prices for the stickers and themes it sells.

What is Letter Sealing in LINE?

The encryption layer named in LINE's listing, described as encrypting messages, call history and location information. The listing does not say whether it is on by default or a setting you turn on yourself.

Does LINE work on a computer?

The listing says LINE runs on mobile, desktop and Wear OS, and describes a smartwatch path that shows messages and adds a complication to the watch face.

What is Keep Memo?

A personal chatroom inside LINE for temporarily storing messages, photos and videos, as described in its listing. "Temporarily" is the listing's own word, so treat it as scratch space rather than storage.
