OHaNAS専用アプリ　OHaNASのキモチ is a free lifestyle application available on Android devices. This app allows users to experience fun conversations with the Ohanas (OHaNAS/おはなす) robot by connecting it via Bluetooth to their smartphone or tablet. The app's main features include the ability to register and edit profile information necessary for conversing with Ohanas, display conversation history, and connect the Ohanas robot to the cloud-based conversation server. Users can register their profile using hiragana, katakana, numbers, and some special characters but not kanji or alphabet letters. An internet connection is necessary to use this application.

In addition, users can experience up to three rounds of conversation with Ohanas without Bluetooth connection by using the app's built-in microphone and speaker and connecting to the cloud server through in-app purchases. The app offers a quick start guide, user manual, and frequently asked questions section for users to refer to. However, the app does not offer any developer contact information for users to provide feedback or suggestions.
