Bentolingo is an iPhone application developed by LINGUAVISTA LANGUAGE SERVICES PRIVATE LIMITED. It falls under the category of Education & Reference and aims to provide a fun way to teach and learn new languages and cultures. With Bentolingo, users can practice speaking while learning and receive instant feedback on their progress.

One of the main features of Bentolingo is the bento boxes, which are created by real chefs. Each bento box consists of a language concept along with a few words and sentences. Users can choose a bento that they like, whether it's in text, video, or GIF format, and practice as many times as they want. Additionally, users can purchase bento boxes using miles, which can be earned for free by checking in daily or by practicing speaking in each bento.

Bentolingo also offers the opportunity for users to become a chef themselves. Through the Passport feature, users can apply to be a chef on Bentolingo and create their own bento boxes by recording words and sentences. In Passport, users can keep track of their purchased bento boxes and saved words and sentences. The application also provides a translation feature called Translate, which supports quick translation between multiple languages.

Furthermore, Bentolingo allows users to discover new friends and invite them to chat and practice their language skills. Users can also ask questions to the chefs and learn beyond what's provided in the bento boxes.

Overall, Bentolingo offers an engaging and interactive platform for language learning, with its bento boxes, translation feature, and chat functionality.
