About Call Recorder – Cube ACR
As someone who needs to recall details from client calls and interviews, I’ve tried a few call recorders that were clunky or unreliable. I downloaded Cube ACR on a whim, and after using it for a few months, it’s become my go-to. It’s a free app from Cube Apps Ltd that does one job—recording phone calls—and it does it well without overcomplicating things.
Features & Highlights
The automatic recording feature is the star for me. I can set it to record all calls, or just ones from specific contacts. I have it set to auto-record my project manager and clients, so I never forget to hit the button during a hectic workday. The audio quality is clear enough that I can understand every word, even when I’m on speakerphone in my home office. I also appreciate that it saves recordings in MP4 format by default, which plays on anything. While I haven’t used the cloud backup to Google Drive much, it’s a solid option for someone worried about losing files if their phone dies.
User Experience
The first time I needed to reference a recording was a game-changer. A client gave me a long list of revision notes over the phone, and instead of scrambling to write everything down, I just listened back to the recording at my desk. The interface is straightforward: a simple list of calls with the contact name, number, and date. Tapping one plays it immediately. I remember trying to find a specific snippet from a week-old call; I just searched the contact’s name and found it in seconds. It doesn’t have a fancy transcription service, but for a free app, the organization is spot-on.
Pricing
The app is free with ads. You’ll see a small banner ad at the bottom of the main screen, which is a fair trade-off for the core functionality. There’s a paid “Pro” version that removes ads and unlocks some extra features like more cloud storage and advanced recording formats. For my needs—just reliable recording and playback—the free version has been completely sufficient. I don’t feel pressured to upgrade, which is nice.
Updates & Support
I get an update for Cube ACR every few weeks, usually with minor bug fixes or compatibility improvements for new Android versions. When Android 14 broke recording on some other apps I tested, Cube ACR had a fix out relatively quickly. I had one issue where a recording failed, so I used the in-app feedback form. I got a generic “we’ll look into it” email, but the next app update a week later mentioned fixes for recording failures on my phone model. So, while support isn’t personal, they do seem to address problems.
Security & Privacy
I downloaded it directly from the Google Play Store, which always feels safer than sideloading APKs. The app needs extensive permissions—microphone, phone, contacts, storage—which is obvious for a call recorder. Their privacy policy states that call recordings are stored locally on your device unless you choose to back them up to your own cloud account. The ads in the free version are standard and I haven’t noticed any weird tracking pop-ups. It’s important to remember that call recording laws vary by location, and it’s your responsibility to follow them, a disclaimer the app rightly provides.
Can I set Cube ACR to automatically record only certain contacts?
Yes, you can. In the settings, you can choose to record all calls or only calls from specific contacts, which is perfect for making sure you never miss an important client or project manager call without recording every conversation.
What file format does Cube ACR use for recordings?
By default, Cube ACR saves recordings in MP4 format, which is widely compatible and plays on almost any device or media player without needing extra software.
Why can't I find a specific old recording in Cube ACR?
The app organizes recordings in a simple list with contact names, numbers, and dates. You can quickly find a specific snippet by searching the contact's name directly from the main screen, and it will show up in seconds.
How do I stop the banner ads in the free version of Cube ACR?
The free version shows a small banner ad at the bottom of the screen. To remove ads and unlock extra features like more cloud storage and advanced recording formats, you can upgrade to the paid Pro version.
How does Cube ACR compare to other call recorders like Automatic Call Recorder?
Cube ACR stands out for its simplicity and reliability, with automatic recording by contact and clear audio quality even on speakerphone. While Automatic Call Recorder offers similar features, Cube ACR's interface is more straightforward and less clunky for daily use.
