Best Call Recorder: Top Picks & Buying Guide

The top pick for most people is Cube ACR because it offers the broadest compatibility across Android devices, records both sides of the conversation clearly, and includes cloud backup and transcription features without a subscription wall. Its main limitation is that it works only on Android; iPhone users will need a different solution, which we cover below.

What to Look For

Call recording apps vary wildly in what they can actually do, and the differences come down to a few key criteria:

• OS and device compatibility: Android allows direct call recording on most phones, but some manufacturers (Samsung, Xiaomi, Pixel) restrict access to the microphone during calls. iPhone has no native call recording; you must use a workaround like a three-way call with a recording service or a jailbreak (not recommended).
• Recording method: Apps either record the call directly (best quality) or use the speakerphone and microphone (acceptable but lower quality). Direct recording requires the app to have accessibility or overlay permissions, which some phones block.
• Automatic vs. manual: The best apps can automatically record every call or only specific contacts. Manual recording (pressing a button during a call) is a fallback when automatic isn’t possible.
• Storage and sharing: Look for apps that let you set a file size limit, auto-delete old recordings, and share recordings via cloud services (Google Drive, Dropbox) or messaging apps.
• Transcription: Some apps offer speech-to-text, but accuracy varies widely and often requires a subscription. If you need transcripts, check if the app offers them and whether they are on-device or cloud-based.
• Privacy and legality: Recording calls without consent is illegal in many jurisdictions. The app itself is not illegal, but how you use it may be. Always inform the other party that you are recording.

Top Recommendations

Cube ACR (Android)

Strengths: The most reliable automatic call recorder for Android. It works on most phones by using the accessibility service to capture the call audio directly, resulting in clear recordings. It offers cloud backup, transcription (paid), and a clean interface.

Trade-offs: Requires setup on some phones (Samsung, Pixel) to enable the accessibility service. On Android 10+ and later, Google restricts call recording to apps that are set as the default phone app, so Cube ACR may not work on all devices without a workaround. No iOS version.

Best for: Android users who want a set-and-forget solution and are willing to tweak settings for their specific phone model.

Automatic Call Recorder (Android)

Strengths: A simple, no-frills app that records calls automatically with minimal setup. It supports cloud upload and has a built-in player. It’s free with ads, and the paid version removes ads and adds transcription.

Trade-offs: Same Android 10+ limitations as Cube ACR. The free version can be intrusive with ads. The interface feels dated compared to Cube ACR.

Best for: Users who want a straightforward, free option and don’t need advanced features.

Rev Call Recorder (iPhone)

Strengths: The best free option for iPhone users. It records calls via a three-way conference call with Rev’s recording line, and the recording is available immediately in the app. It also offers paid transcription services.

Trade-offs: You must manually start the recording by calling the Rev line and merging the calls. It uses your cellular minutes, and the recording quality depends on your carrier. The free version limits recording length to 15 minutes per call.

Best for: iPhone users who need occasional call recording and don’t mind the manual process.

Google Voice (iPhone & Android)

Strengths: Free, built-in call recording for calls made through Google Voice. You can enable recording in settings, and the app will announce that the call is being recorded (which is legally required in many places). Recordings are stored in your Google Voice inbox and can be downloaded.

Trade-offs: Only works for calls made to or from your Google Voice number, not your regular carrier number. You cannot record incoming calls automatically; you must press 4 during the call to start recording. No transcription.

Best for: Users who already use Google Voice and want a no-cost, legal option.

Call Recorder – ACR (iPhone)

Strengths: This app works similarly to Rev but offers a one-time purchase option instead of a subscription. It uses a conference call method and provides decent recording quality.

Trade-offs: The manual setup is the same as Rev, and you need to call the recording line each time. Some users report occasional dropped calls during the merge process.

Best for: iPhone users who prefer a one-time payment over a subscription.

Boldbeast Call Recorder (Android)

Strengths: Known for its aggressive compatibility workarounds, Boldbeast supports many phone models that other apps fail on. It offers automatic recording, cloud backup, and a variety of recording formats.

Trade-offs: The interface is clunky and the app is not free (trial then paid). It requires significant configuration on some devices.

Best for: Users with older or less common Android phones who have tried other apps without success.

How to Choose

Budget: Free options like Google Voice and Rev (with limited length) are sufficient for occasional use. If you record calls daily, consider a paid app like Cube ACR (one-time purchase) or Boldbeast (trial then license) to avoid ads and get reliable automatic recording.

Use case: For journalists or professionals who need transcripts, invest in an app with good transcription (Cube ACR or Rev’s paid service). For personal use, a simple free recorder is fine. If you need to record calls with clients, automatic recording is essential, so choose an Android app that supports it on your device.

Common trade-offs: The biggest trade-off is between automatic recording and compatibility. On Android, automatic recording often requires granting accessibility permissions, which some users find invasive. On iPhone, you can only record manually via a conference call, which is inconvenient but unavoidable without jailbreaking. Also, consider storage: recordings can eat up space quickly, so choose an app that allows you to set a max file size and auto-delete old files.

Frequently Asked Questions

Is it legal to record phone calls?

Laws vary by country and state. In many places, only one party needs to consent (you), but in others, all parties must consent. Always inform the other person that you are recording to be safe.

Why doesn’t call recording work on my Android phone?

Starting with Android 10, Google restricts call recording to apps that are set as the default phone app. Many manufacturers also block microphone access during calls. Check if your phone has a built-in call recorder (Samsung, Xiaomi, etc.) or try an app that uses the accessibility service, like Cube ACR.

Can I record calls on iPhone without a third-party app?

No. iOS does not allow apps to access the phone line directly. The only built-in option is Google Voice, but that only works for calls made through Google Voice. Otherwise, you must use a three-way call service like Rev.

Do call recorder apps record both sides of the conversation?

Yes, most do, but the quality of the other party’s voice depends on the recording method. Direct recording (Android) captures both sides clearly. Speakerphone recording (iPhone) can pick up the other party but may have echo or background noise.

How much storage do call recordings use?

A one-hour recording is roughly 30-60 MB depending on the format (MP3 vs. WAV). Most apps let you choose a lower bitrate to save space. Cloud backup is recommended.

Can I record WhatsApp or Skype calls?

Most call recorder apps only record regular cellular calls. For VoIP calls, you may need a dedicated app like “Cube ACR” which supports some VoIP apps, or use a screen recorder that captures audio (Android). On iPhone, this is not possible without a computer.

Bottom Line

For Android users, Cube ACR is the best overall choice due to its reliability and features. If you’re on an iPhone, Rev Call Recorder is the most practical free option, despite the manual setup. For a simple, no-cost solution, Google Voice works well if you don’t mind the limitations. Always check the laws in your area and inform the other party before recording.
