Smartphone users rely heavily on calling and communication features, but the default phone app on many Android devices lacks customization, privacy tools, and advanced calling features. Enter ACR Phone, an all-in-one dialer, spam blocker, and call recorder app designed to take your phone calling experience to the next level. Available on the Google Play Store, this feature-rich communication utility is quickly gaining traction among users looking for more control, privacy, and functionality in their Android calling app.
What Is ACR Phone?
ACR Phone is an Android phone and communication app developed by NLL APPS that can fully replace your device’s default dialer with a more powerful and customizable calling tool. Unlike simple dialers, ACR Phone combines calling, call recording, spam blocking, SIP support, call notes, and more — all within one unified app. It’s suitable for users who want better privacy controls, detailed call logs, advanced features, and modern interface design.
With over 50 lakh+ downloads and a strong user rating, ACR Phone continues to evolve and add new tools for everyday communication comfort.
Key Features of ACR Phone
Custom Dialer with Fresh Interface
ACR Phone replaces your default dialer with a clean and modern design, including dark theme support, intuitive navigation, and a user-friendly call log review. You can make and receive calls, search contacts quickly, and switch between call history and contacts effortlessly.

Spam Call Blocker & Blacklist
Spam and unwanted calls can be frustrating. With ACR Phone’s offline blacklist and spam blocker, you can prevent incoming calls from unwanted numbers — manually adding them from call logs or inputting them directly. You can choose exact or relaxed matching rules for flexible control.
Call Recording
One of ACR Phone’s standout features is its built-in call recording (on supported devices). You can record incoming and outgoing calls manually or with additional tools. A companion tool called ACR Phone Helper (APH) enhances recording capabilities on newer Android versions where direct call recording is restricted.
Call Announcer & Caller ID
Thanks to the call announcer feature, ACR Phone can announce the caller’s name and number aloud — helping you know who’s calling without looking at the screen. This is especially useful when using headphones or Bluetooth.
Call Notes & Reminders
Instead of forgetting important details, you can add notes or reminders for a call during or after the conversation. This is ideal for professionals or business users who need context for future communication.
SIP Client & Dual SIM Support
On supported Android devices, ACR Phone offers SIP (VoIP) calling — enabling internet-based calls — and full dual SIM compatibility, letting you manage multiple networks efficiently.
Backup & Export
Keep your call logs, contacts, and blacklist safe with export and import tools. This feature simplifies migrating to a new device or restoring settings after maintenance.
Benefits of Using ACR Phone
- Improved privacy and fewer unsolicited calls with advanced spam blocking.
- Convenient call recording and annotations for work or personal use.
- Customization and additional calling tools missing from default dialers.
If you want a powerful dialer replacement with enhanced privacy controls, customizable calling experience, call recording, and a fresh Android interface, ACR Phone is worth exploring. Its combination of tools makes it one of the most feature-rich calling apps available on the Google Play Store today.
