Main Features of ACR Phone
Powerful Dialer Replacement
ACR Phone replaces your default Android dialer with a sleek, modern interface that supports rich contact management and quick access to call logs. You can easily view outgoing, incoming, and missed calls in a clean layout, making it easier to stay organized.
Offline Spam Call Blocker
The built-in spam call blocker lets you create a blacklist of unwanted numbers. These numbers are blocked automatically without needing an internet connection. You can add numbers manually or from your call log and customize blocking rules for exact or relaxed matching.
Call Recording (On Supported Devices)
ACR Phone includes call recording features for compatible devices. While limitations exist depending on Android versions (particularly on Android 10+ due to system policies), the app still offers useful recording capabilities where supported.
Call Notes & Reminders
Users can create call notes and reminders during or after calls — perfect for keeping track of important details discussed on a call or for setting follow-up reminders.
Backup & Restore
ACR Phone supports exporting and importing call logs, contacts, and your blacklist database, making migration between devices or backups easier.
Call Announcer & Custom Screen
The app can announce incoming calls by reading out contact names or numbers. You can also customize the call screen with photos or video backgrounds per contact.

SIP Client & Dual SIM Support
ACR Phone includes a SIP client, enabling VoIP calls over Wi-Fi or mobile data. It also supports dual SIM devices and lets you choose which SIM to use before calling.
Why Use ACR Phone?
ACR Phone stands out as a feature-rich Android dialer app that gives users more control over their calling experience. Whether it’s blocking spam calls, recording important conversations, adding notes, or managing contacts and call logs more efficiently, this app delivers tools that go beyond a basic dialer.
Its privacy-focused permissions model also means your personal data remains on your device rather than being uploaded elsewhere.
If you’re looking for a comprehensive dialer app that enhances calling features on your Android device, ACR Phone is worth trying. It blends utility with customization and gives users added tools for handling calls more effectively — all without sacrificing performance or privacy.
