Replaces bulky phone apps by putting rapid contact access, SIM selection, and a locked private contact area at the center of calling workflows. GrinchStudio built this Android dialer for users who prefer minimal, local-first apps. The interface adapts to the device theme and exposes direct shortcuts to popular messaging apps, plus configurable call handling and call logs for people who manage many connections on a single device.

What Rivo does for everyday calling

Rivo routes basic telephony tasks into a compact workflow. The app focuses on dialing, inbound handling, and contact access with features that avoid clutter. It places call logs and social-app shortcuts next to contact details and supports assignable outbound SIM selection per contact. The interface uses dynamic system theming and offers customizable dialpad layouts, aiming to reduce friction when you place or return calls.

How private are your conversations and data

Privacy choices are explicit and local-first. The project is open source under GPL v3 and the app declares no trackers, which frames data handling around on-device storage. A private contact vault secures entries behind biometrics or the device PIN. The app also records calls via Shizuku ADB permissions or a microphone fallback, so recorded audio storage remains under the user's control rather than routed through external servers.

How Rivo handles device compatibility and notifications

Rivo targets modern Android devices and gives granular call controls. Material You theming and Jetpack Compose features work best on recent Android versions. Call blocking provides options to decline or silence calls plus a dedicated log for blocked numbers. Social-app shortcuts connect contact records to WhatsApp, Telegram, and Signal, and the Dual SIM behavior includes carrier tags and preferred SIM memory to simplify outbound selection on devices with two lines.

A focused choice for privacy-minded Android callers

Rivo suits Android users who want a compact, locally controlled replacement for the stock phone app and who accept some hands-on setup for advanced functions. The app favors device-resident data and customization over cloud synchronization. Users who need cross-device call continuity or plug-and-play call recording without extra permissions should consider that those capabilities require platform-specific setup or additional tools.
