'Asuken' Launches Official Version of Weekly 'Review Report' Feature to Support Sustainable Eating Habits

asken Inc. (Shinjuku-ku, Tokyo; CEO Junro Ama, hereinafter "the Company"), developer and operator of 'Asuken'—Japan's No.1*1 AI-powered diet management app with over 14 million cumulative members—announces the official launch of its weekly meal review feature, the "Review Report," starting June 29, 2026 (Mon).

Initially released as a beta version in May 2026, the feature has now transitioned to its official version with enhanced report analysis accuracy and a newly added access point from the 'Asuken' app's home screen. This update makes it easier than ever for users to review their dietary changes on a regular basis.

Analysis of user data collected during the beta period revealed that users who consistently viewed the "Review Report" were more likely to maintain long-term food logging habits and showed better outcomes in weight management.

About the "Review Report"

The "Review Report" compiles daily food logs into a single weekly report, enabling users to reflect on their eating patterns over a seven-day cycle. Leveraging Asuken's structured food database and meal record data, the feature uses proprietary AI analysis to deliver personalized feedback tailored to each user's dietary trends. Instead of merely reviewing individual meal entries, users receive summarized insights on their weekly habits, making it easier to understand their current diet status, recognize progress, and identify actionable improvement points.

A new direct access point to the "Review Report" has been added to the app's home screen, making it easier to view reports and helping users incorporate weekly dietary reflection into their daily routines seamlessly.
