LivyTalk is a free Android app that allows users to make IP and video calls with ease. Compatible with NTT East/West's NGN services, including Hikari Phone, the app enables users to make video calls with other LivyTalk users and various Hikari Phone-compatible devices. LivyTalk also supports voice-only calls with traditional telephone networks, including landlines, mobile phones, and IP telephony.

The app offers high-quality voice calls, an echo canceller, and a 30-day free trial for the comfortable video call feature. Users can purchase the "High-quality & Video Call Function Option" to continue using the video call feature, high-quality voice calls, and the echo canceller beyond the free trial period.

LivyTalk is compatible with Android 4.1 or later smartphones/tablets (Android 7 or later is recommended). Please note that, starting from version, the app no longer shares call history with the device's mobile calls due to Google Play's policy changes. However, users can still access the call history from their device's call log and address book.

Overall, LivyTalk is a fantastic app for anyone looking for a reliable and efficient way to make IP and video calls.
