How to record calls on iPhone legally in Spain

Recording calls on iPhone isn’t as straightforward as on Android, and in Spain you also need to consider the law. I researched this topic thoroughly because I needed to record phone interviews for a project. I’ll explain how to record calls on iPhone legally in Spain, with methods that actually work and the legal limits you should know.

First: is it legal to record calls in Spain?

Before pressing any button, let’s clarify the legal framework. This is fundamental because an illegal recording not only fails as evidence but can get you into trouble.

Spanish law on recordings

In Spain, recording your own conversations is legal if you are part of the conversation. This is based on Article 18 of the Constitution and case law from the Supreme Court.

Legal recording:

• You record a conversation you’re part of
• You don’t need the other party’s consent
• The recording can be used as evidence in court

Illegal recording:

• You record a conversation you’re not part of
• You install recording software on someone else’s phone
• You record for blackmail or extortion

GDPR and recordings

The General Data Protection Regulation (GDPR) adds nuances:

• If you record for personal reasons (private use), GDPR obligations don’t apply
• If you record for professional or commercial purposes, you must inform the other party
• You cannot publish the recording without consent (except as judicial evidence)

Important: In Spain, recording your own conversation is legal. What you can’t do is record others’ conversations, publish them without permission, or use them for blackmail. When in doubt, inform the other party.

Differences with other countries

The law varies by country:

• Spain: Unilateral (only needs consent from one party — yours)
• UK, USA (varies by state): Some require consent from all parties
• Germany, France: Require consent from the other party

Methods to record calls on iPhone

Apple doesn’t include a native call recording feature for privacy and legal reasons. But there are several ways to do it:

Method 1: Third-party apps with conference (most reliable)

Works by creating a conference call with a recording number. It’s the most used and reliable method.

Recommended apps:

Rev Call Recorder:

• Free to record
• Adds a Rev number to the call as conference
• Recording saved to the cloud
• Simple interface

TapeACall Pro:

• Paid app (~€12/year)
• Conference method
• Unlimited recordings
• MP3 export

How it works:

1. Open the recording app
2. Tap “Record” — the app dials a service number
3. Merge the original call with the app’s number
4. The app records the conference
5. When you hang up, the recording saves automatically

Quality: Audio quality is good but not perfect. Works better with good 4G/5G coverage.

Method 2: External recorder with adapter

Connect a physical recording device to your iPhone via Lightning or USB-C port.

Options:

• Wired recorders: Connect to the charging port and capture call audio
• Bluetooth recorders: Connect as a headset and record audio

Pros:

• Doesn’t depend on apps or internet
• Generally better audio quality
• Doesn’t go through third-party servers

Cons:

• Need to buy extra hardware
• Less convenient than an app
• Some adapters are bulky

Method 3: Use another device to record

The simplest but least professional method. Put the call on speaker and record with another phone, tablet, or recorder.

Pros:

• Free if you already have another device
• Zero setup

Cons:

• Mediocre audio quality
• Captures ambient noise
• Not practical for long calls

Method 4: Transcription services with recording

iOS 19 and apps like Otter.ai can transcribe calls in real time, creating a written record of the conversation.

Apps:

• Otter.ai: Transcribes calls and meetings automatically
• Notta: Similar, with Spanish support
• Google Recorder: Android only, but web alternative exists

Legal note: Transcription is considered a form of recording. If recording is legal in Spain, transcription is too.

Method comparison

My personal recommendation

For casual personal use, TapeACall or Rev are the best options. They’re easy, cheap, and reliable.

For professional use (interviews, journalism, legal documentation), I recommend a good quality external recorder. Audio will be cleaner and you don’t depend on mobile coverage.

If you only need a written record, use Otter.ai or Notta to transcribe in real time. It’s less intrusive and gives you editable text immediately.

Frequently asked questions

Can I use the recording as evidence in court in Spain?

Yes, if the recording is legal (you’re part of the conversation). Spanish courts accept own recordings as evidence. However, the judge will evaluate its probative weight based on context.

Do I need to tell the other person I’m recording?

Legally in Spain, it’s not mandatory if you’re recording your own conversation and using it personally. However, for ethics and courtesy, it’s always recommended to inform. In professional contexts, it’s mandatory under GDPR.

Will Apple allow call recording in the future?

It’s possible. Apple has added call transcription features in iOS 19 for certain markets. Full call recording could arrive in future versions, likely with visual indicators for the other party.

Are recording apps safe?

Well-known apps (Rev, TapeACall) are safe and privacy-respecting. However, recordings go through their servers. If privacy is your top priority, use an external recorder or the speaker method.

Conclusion

Recording calls on iPhone in Spain is legal when you’re part of the conversation, and there are reliable methods to do it. My recommendation is to start with an app like TapeACall or Rev to try it out, and if you need higher quality or privacy, invest in an external recorder. Always remember the legal limits: recording your conversation is fine, recording others’ isn’t.
