Recording a call is useful in various situations: a job interview, an agreement with a service provider, a meeting you need to review later. What many people don't know is that recording calls on mobile phones has become more restricted in recent years. Android has limited apps' access to call audio, and the iPhone has never allowed this for external apps. Therefore, the result varies considerably from device to device.
In this article you will see which call recording apps are still published on the Brazilian Google Play Store, what each one actually does, what usually goes wrong, and what to do when none of them work on your device. All links lead to the official listing on the store: do not download call recorders via APK or links outside of the Play Store, because this type of app requests heavy permissions and is precisely where malicious programs most often appear.
Before installing: why it sometimes doesn't work
In the latest versions of Android, a common app can no longer capture audio coming from the other end of the line. Some manufacturers leave recording active in the phone's dialer, others do not. The practical result is that the same app can record the entire conversation on one phone, record only your voice on another, and record nothing on a third. None of the apps on this list can get around this, and be wary of any that promise to record on every device.
Two tips before downloading anything. First, open your phone's phone app and check in settings if there's already a call recording option: on many models it comes pre-installed and works better than any third-party app. Second, test it by calling a friend before relying on the recording for a conversation that matters.
Apps for Recording Calls on Android
The four apps below are published on the Brazilian Google Play Store. All are free to download, display ads, and unlock extra features through in-app purchases.
1. ACR Phone
O ACR Phone, Call Recorder ACR, from NLL APPS, is the successor to the old Call Recorder ACR, which is no longer available. It replaces the phone app on your cell phone: you make and receive calls from within it, and, when the device allows, recording happens simultaneously. It also organizes recordings by contact, which is helpful when you record frequently.
Because it replaces the dialer, it requests quite a few permissions during installation — carefully read what you are authorizing. Recording depends on the Android model and version, so treat the first use as a test. The app store listing indicates that it contains ads and has in-app purchases.

2. Gravador de Chamadas Cube ACR
O Cube ACR, Cube Apps Ltd. is known for attempting to record calls made within messaging apps like WhatsApp, Telegram, and Skype, in addition to regular phone calls. It displays a floating window during the conversation, allowing users to start or stop recording instantly.
The same warning applies: this support for messenger calls doesn't work for all phones, and the app itself warns that compatibility varies depending on the device. It also allows you to mark contacts whose calls should always be recorded, and others whose calls should never be recorded. The app store listing indicates that it contains ads and in-app purchases.

3. Gravador de chamadas – callX
O callX, SMSROBOT LTD's app is a simpler option to set up. It can automatically record all calls or only the ones you choose, and saves the files in a list within the app itself, with the option to protect access and send recordings to the cloud.
It's a good choice for those who want to install it, turn it on, and forget about it. Since your phone's storage space eventually fills up, delete recordings you no longer need from time to time. The app store listing indicates that it contains ads and in-app purchases. View callX's listing on Google Play.
4. Gravador de Voz (quando nada mais funciona)
O Voice Recorder, The Smart Mobi Tools recording device doesn't record the call internally—it records ambient sound through the microphone. It seems like a small detail, but it's a solution that works on any device: you put the call on speakerphone and leave the recorder running, preferably on a second phone or tablet placed nearby.
The quality is lower than a system recording, and ambient noise is also present, so try to find a quiet environment. On the other hand, there are no Android restrictions that interfere. The app's listing in the store indicates that it contains ads and has in-app purchases. View the Voice Recorder listing on Google Play..
And on the iPhone?
On iPhones, Apple doesn't release the audio of an ongoing call to third-party apps. Services that present themselves as call recorders for iPhones work differently: they make a second call to a number from the same company, combine the two calls into a conference call, and record on the server side—almost always on a paid plan and with quality dependent on the carrier.
Before paying for something like this, check on your iPhone if the phone app already has a recording option: in newer versions of iOS, it exists on some devices and announces aloud to both people when it starts. If it doesn't, the practical solution is the same as the last item on the list: speakerphone plus a voice recorder on another device.
Recording, yes; spying, no.
These apps are for saving conversations you're participating in. Installing a recorder on someone else's phone to listen to their calls is another matter entirely: it's an invasion of privacy, and that's not what this article is about. If the concern is with a minor child, the correct approach is transparent parental control, where the child knows the feature is active and the system itself displays a warning.
Even when recording your own conversation, informing the other person that the call is being recorded is the safest approach, and in many cases avoids later disputes about the use of the recording. Store recordings in a safe place and delete what is no longer needed. This text is a practical guideline and does not replace the opinion of a lawyer regarding your case.
Conclusion
There isn't a call recording app that works the same way on every phone today. The least troublesome approach is: first, look for the recording function in the phone app that came with the device; if that's not there, try one of the apps from the Google Play Store mentioned above on a casual call; and if nothing works, use the speakerphone with a voice recorder on another device.
By always downloading from the official store and testing beforehand, you avoid both the shock of discovering that the recording came out muted and the risk of installing a dubious app. Take the opportunity to check out the other articles on the site about mobile phone features.
