## What is FIELD JOURNAL?

FIELD JOURNAL: GUT is a professional digital specification sheet for quantitatively and continuously recording and auditing the daily health status of your beloved dog or cat, especially the stability of their gastrointestinal system, using advanced visual morphological mapping technology. This system instantly analyzes the condition of a specimen from a single photograph and builds a log on an industrial-design dashboard managed with lot numbers. The data feed can be instantly exported as an A4-sized forensic-spec report, visualizing minute changes in your beloved pet's physical condition at a glance.

【Key Features】

INTERNAL GUT AUDIT SYSTEM
Visually maps the image of a photographed or loaded specimen. Quickly calculates the gastrointestinal stability index "GUT-AGE" based on a proprietary algorithm.

AUTOMATED VISUAL MORPHOLOGY
Accumulated data is stored chronologically as an "AUDIT LOG," allowing you to see daily condition changes at a glance. It also includes a "Pet Selection/Assignment Function" to manage logs segmented for each registered pet.

FORENSIC-SPEC REPORT EXPORT
By activating Premium Enterprise Access (subscription), you can integrate all past log data, dates, GUT-AGE, and detailed observation criteria (analysis text) with image data into a beautifully laid-out A4 "Forensic Report," which can be instantly shared and exported as a report file. Ideal for consultations at the veterinary hospital and for strict data recording during senior or growth periods.

TREND ANALYSIS
Equipped with a trend graph function to visually grasp long-term stability trends. Quickly catch signs of sudden biorhythm fluctuations or changes accompanying a new diet.

【About Subscription】
The free version only provides access to a portion of the most recent audit logs. To unlock access to all past logs, view detailed morphological data, and use the A4 report export function, you need to subscribe to Premium Enterprise Access (monthly or annual auto-renewing subscription).

This app supports analysis in English. Simply upload a photo of the specimen, and the AI will automatically detect and analyze the gastrointestinal condition, providing results in English.

Accurate GUT-AGE estimation
Professional morphological analysis
Seamless English interface

If you have concerns about your pet's health or suspect an illness, please be sure to consult a professional veterinarian.
