OpenDialer review
A minimal, open-source Android dialer with core calling tools and quick replies.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OpenDialer is an open-source Android phone app for placing and receiving calls, aimed at people who want a minimal dialer rather than a broader communications suite. Its core tools include a dialpad, contacts list, recent-call log and in-call interface. Users can dial numbers to call, message or add them to contacts. Call conferencing and customizable quick replies when ending calls extend that basic workflow without changing its focused scope.
The app’s platform fit is narrow by design: it is a mobile app for Android, built for Android API 24 and later, and is available under the Apache 2.0 license. The project says OpenDialer must be selected as the device’s default phone app to make and receive calls. That requirement makes it a more natural choice for someone ready to replace their existing phone app than for someone seeking a secondary dialer or a desktop calling option. Its open-source model may appeal to users who value an inspectable, permissively licensed project.
OpenDialer’s strengths are practical rather than expansive: recent calls, contact access, conferencing and quick replies cover everyday calling tasks. It is a reasonable fit for solo users who want those essentials in an open-source app. The narrower scope and community support make it less suited to buyers looking for a wide feature set or dedicated support. Choose it for a lightweight Android calling experience; consider another dialer if broader capabilities or a different platform are central to your needs.
