Life Log Technology

What Life Log Technology does

Life Log Technology (ライフログテクノロジー株式会社) develops and operates Calomeal (カロミル), an AI-powered health management application for the Japanese market. The core product is a smartphone app that uses proprietary computer vision to recognize meals from photos, calculate seven core nutrients plus 22 vitamins and minerals, and predict weight and body fat percentage one to six months ahead. A granted patent (Patent #6355147) protects automated camera-roll meal analysis, and the food database covers more than 100,000 items, achieving 90%+ coverage of typical Japanese meals. The platform integrates with Apple Health, Google Fit, Health Connect, OMRON connect, Fitbit, Garmin, and LINE.

The company operates a multi-product platform built around the consumer app. B2B offerings include Calomeal Advice (professional nutrition guidance for trainers, dietitians, and clinics), Calomeal Well-being (corporate wellness events), Calomeal WebView (embedded SDK for third-party apps), the Calomeal API (distributed via KDDI IoT Cloud API Market and direct sales), Calomeal Hokenshidou (online specific health guidance system aligned with Japan's health insurance framework), and Calomeal Data Solution (analytics on the user meal database). Specialized variants include Performance Navi for athletes and Calomeal PFC Pro Report for sports nutrition.

Go-to-market combines a freemium consumer funnel through App Store and Google Play with enterprise direct sales to healthcare institutions, corporate wellness buyers, fitness gyms, and municipal public health programs. Pricing spans consumer in-app purchases of $0.99-$4.49 per feature, trainer seats at 5,000 JPY per person per quarter, and corporate wellness subscriptions at a 100,000 JPY per month base plus per-seat premiums. The company is venture-backed, with cumulative disclosed funding of approximately 1.7 billion JPY from investors including three TSE-listed strategic partners (Advantage Risk Management, TIS, Shin Nippon Biomedical Laboratories) and Digital Garage-backed DG Lab1.

Direct peers

• FiNC Technologies: Tokyo-based AI health/fitness app combining diet tracking, exercise, and coaching. Directly comparable as a Japanese consumer-plus-enterprise health platform with AI personalization, large user base, and corporate wellness sales motion.
• MyFitnessPal: Global food/database diet-tracking leader with a calorie-counting model similar to Calomeal's free-tier offering. Direct competitor for consumer mindshare and an indirect competitor for corporate wellness budgets.
• Noom: Subscription diet-tracking and coaching app with human-coach overlay and B2B corporate wellness sales. Comparable product surface (logging + coaching) and enterprise GTM motion.
• Lifesum: Subscription-based diet, calorie, and meal-planning app with food database and macro tracking. Closely mirrors Calomeal's freemium-plus-premium model and nutrition-coaching angle.
• Lose It!: US calorie-counting and food database app with photo/AI logging, premium tier, and corporate wellness (Lose It! for Business). Overlaps Calomeal on core food recognition, premium subscription, and enterprise GTM.

Broad incumbents

• TANITA Health Link: Japanese health-device manufacturer operating a body-composition/app ecosystem (TANITA Health Planet). Competes on integrated device + app nutrition tracking and is a natural adjacent incumbent in the same category as Calomeal's vital-measurement AI.

Others

• OMRON Healthcare: Device-side partner/integrator of Calomeal that also runs competing health management apps (OMRON connect). Relevant as an ecosystem participant that could either deepen integration or compete directly on app+device experiences.
• Healthcare Technologies (HealthTech): Operates HELPO remote specific health guidance service that embeds Calomeal WebView. A partner-distributor for Calomeal in the specific health guidance vertical and a relevant comparable in Japan's digital health-guidance space.

Regional players
