5 Best LINE Call Recording Methods Tested in 2026: Which Is Most Reliable on iPhone, Android, and Desktop?

Before You Start: Identify Your Recording Needs

LINE does not include built-in call recording for privacy reasons. To record LINE voice or video calls, you'll need to use device-level features or third-party tools.

Before choosing a method, consider these three questions:

• Are you using LINE on iPhone, Android, or desktop? The recording approach varies significantly by platform.
• Do you need two-way audio (both sides clearly audible), or is recording only your side sufficient?
• After recording, do you just need the audio file, or would you prefer a transcript and meeting summary?

For work meetings, client interviews, or class notes, simply capturing audio often isn't enough. You'll still need to spend time replaying, transcribing, and summarizing key points. In such cases, using an AI tool to process the recording can save far more time than manual organization.

Also note: In the U.S., recording calls generally requires one-party consent in most states, but some states require all-party consent. For business purposes, it's always safer to inform the other party and obtain permission.

Method 1: iPhone Users: iOS 18 Integrated Call Recording

If your iPhone is updated to iOS 18 or later, this is the most straightforward and completely free method.

Here's how to do it:

1. Open LINE, go to Settings, and enable "Integrate with iPhone Calls."
2. After answering or placing a LINE call, tap the recording icon in the top-left corner of the screen.
3. The system will play a voice prompt notifying both parties that the call is being recorded.
4. The recording is automatically saved to the Voice Memos app, capturing both sides of the conversation.

The advantage of this method is that no additional app is required, and iOS-level recording captures both voices clearly. The downside is the audible notification, which makes it unsuitable for discreet recording.

If you want to search the content or generate summaries after recording, you can upload the audio file from Voice Memos to an AI tool like Tinrec, which will transcribe it and highlight key points.

Method 2: Android Users: Cube ACR for Automatic Recording

Android's more open system allows third-party call recording apps to handle LINE calls. Cube ACR is currently the most discussed option in user communities.

After installation, follow the app's instructions to grant microphone, notification, and background execution permissions. Once set up, when you make or receive a LINE call, a blue-purple floating window will appear with a microphone icon, indicating that recording is in progress.

After the call ends, open Cube ACR to find the recording and choose to save it to your device or cloud storage.

Note that Android devices vary widely; some models may have system restrictions or battery-saving features that prevent Cube ACR from working properly. If you notice only one side of the audio or no recording at all, check the app's "Audio Source" settings or switch to screen recording with "Media Audio Recording."

Cube ACR's strengths are automation and simplicity, but recording quality depends on your phone model and call environment. Additionally, it does not support iOS.

Method 3: Desktop LINE: Use Screen Recording Software to Capture Both Sides

If you typically join LINE meetings or voice discussions on your computer, desktop recording offers more flexibility than mobile.

Simply use your computer's screen recording or audio capture software, enabling both "Microphone" and "System Audio" to record both sides of the call. Most desktop recording tools support this setup, and the process is generally the same:

1. Open your recording software and select "Audio Recording" or "Screen Recording" mode.
2. In the audio sources, enable both microphone and system audio.
3. Start the LINE call, then press the record button.
4. Stop recording after the call ends and export the audio file.

This method is not limited by phone model and typically yields better audio quality than phone speaker recording. The downside is that you must be at your computer during the call, making it unsuitable for on-the-go situations.

If you use the Tinrec desktop app, you can record and get real-time transcription simultaneously. It captures system audio to record online meetings from Zoom, Google Meet, Microsoft Teams, and others—no need to add a bot to the meeting.

Method 4: Video Calls: Screen Recording in Addition to Audio

For LINE video calls, you might want to preserve the visual content as well. In that case, screen recording on your phone or computer is the primary approach.

iPhone users can start screen recording from the Control Center and long-press the record button to enable the microphone, capturing both video and audio. Some Android models have screen recording in the quick settings menu; choose "Media Audio Recording" in the settings.

On desktop, use screen recording software to capture both the LINE window and system audio.

Screen recordings produce large files. To organize the content later, consider extracting the audio or uploading the video directly to Tinrec for transcription. Tinrec supports both audio and video file uploads, allowing you to extract transcripts and key points directly from video recordings.

Method 5: After Recording: Use Tinrec to Turn Audio into Usable Meeting Notes

Many people overlook this: recording is just the first step; the real time cost is in "organizing."

A 60-minute LINE call can take two to three hours to manually replay and transcribe. If you have several calls to document each week, this time cost becomes significant.

Tinrec automates this process. You can upload audio files from any of the methods above to Tinrec, and it will:

• Automatically transcribe the audio, supporting Chinese, Traditional Chinese, and multilingual content.
• Generate AI summaries, chapters, and key points to quickly grasp the call's main topics.
• Extract action items and compile them into a to-do list.
• Support AI Q&A, allowing you to ask questions like "What requirements did the client mention?" or "What was the conclusion?"
• Export to Notion, Google Docs, OneNote, and other tools for continued workflow.

If you're on a LINE meeting on your computer, the Tinrec desktop app can directly capture system audio, transcribing in real time so you have the transcript and summary immediately after the call.

The free plan offers basic usage credits, suitable for testing with one recording. If you have consistent weekly recording needs, consider the Pro plan.

FAQ and Troubleshooting

Q1: Why doesn't LINE have built-in call recording?

Primarily to protect user privacy. Call recording laws vary significantly across countries, so LINE chooses not to offer this feature within the app, leaving recording needs to device systems or third-party tools.

Q2: Why does my iPhone only record one side of the LINE call?

If you're using iOS 18 or earlier, or haven't enabled "Integrate with iPhone Calls," you may only capture your own voice. Ensure your system is updated and enable the integration feature in LINE settings.

Q3: What should I do if Cube ACR isn't recording LINE calls?

This is a common issue due to Android device differences. First, check that all app permissions are granted, especially microphone and background execution. If it still doesn't work, using the system's built-in screen recording with "Media Audio Recording" is a more reliable alternative.

Q4: How can I quickly summarize a long recorded call?

Manual transcription is time-consuming. Upload the audio to Tinrec, let AI automatically transcribe, generate summaries and to-dos, and use the Q&A feature to find specific sections. This can reduce organization time from hours to minutes.

Q5: What legal issues should I consider when recording LINE calls?

In the U.S., federal law allows one-party consent, but many states require all-party consent. For business meetings, client communications, or situations involving third-party privacy, it's best to inform participants and obtain consent to avoid legal disputes.

Advanced Tips: 3 Ways to Maximize the Value of LINE Recordings

1. Turn Transcripts into a Searchable Database

The biggest issue with audio files is that they're hard to search. Once transcribed, all content becomes searchable text. Tinrec's AI Q&A can query across multiple recordings, such as "What were the pricing terms discussed with the client last month?"—no need to replay each file.

2. Centralize Meeting Recordings with Team Spaces

If you and colleagues frequently use LINE for meetings, instead of scattering recordings across individual devices, upload them to a Tinrec team space. Members can access historical meeting data, admins can manage seats and usage, and data remains intact even if a member leaves.

3. Generate Reports or Tables Directly After Recording

Tinrec's Agent post-processing feature can generate reports, tables, and documents based on meeting content. For example, turn client requirements into a summary or convert discussion points into a to-do list for next steps.

Alternatives to Tinrec

Otter.ai is a mature AI meeting assistant, strong in English meetings but not always optimal for Chinese content. Notta performs well in multilingual transcription, suitable for users needing subtitles and translation. If you only need basic recording without AI organization, your phone's built-in screen recorder or voice memos can suffice.

However, if your goal is to turn LINE call content into usable work materials, Tinrec offers more complete integration for Chinese meeting organization, bot-free recording, and team space management.

Conclusion

LINE doesn't offer built-in recording, but there are at least several practical paths: iPhone's integrated call recording, Android's Cube ACR, desktop screen recording, and video screen recording. The choice depends on your device, call context, and post-call organization needs.

If you only occasionally record a call, built-in features or Cube ACR may suffice. But if you have weekly meetings, interviews, or client communications that need documentation, using Tinrec to turn recordings into transcripts, summaries, and to-dos is more efficient. Try the free plan with one of your recordings to experience the difference between "recorded" and "usable."
