Review momentum

faster than 0% of Health & Fitness apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About 16h Fasting & Gut Health Log
Achieve your ideal body and mental state through gut health and fasting.
“Gut Health Fasting” is a total healthcare app that combines fasting with gut health tracking to help you discover the optimal lifestyle for your body. Beyond supporting 16-hour fasting practices, it analyzes the correlations between your meals, hydration, physical condition, and bowel movements, visualizing “what works best for you” through data.
【Key Features】
■ “Fasting Timer” that shows your body's changes
It doesn't just count time. It notifies you of changes happening inside your body at each stage—from “Fat Burning Begins” to “Autophagy (Cell Rejuvenation)” and “Detox”—as you progress from 4 to 72 hours. This helps you maintain motivation and continue fasting without strain.
■ Gut-Focused “Gut Environment Log”
Beyond stool consistency based on the Bristol Stool Scale, it records color, volume, odor, sense of relief (incomplete evacuation), and ease of passage in detail. Catch your gut's SOS signals and objectively track daily changes.
■ “Correlation Analysis Feature” to Find Your Personal Optimal Solution
Automatically analyzes trends based on your recorded data:
・Optimal Fasting Duration: “Is 16 hours better, or 12 hours?” Calculates the fasting time that best aligns with your gut's rhythm.
・Food & Hydration Compatibility: Identifies “foods that suit your gut,” “foods that don't suit your gut,” and your optimal hydration level.
・7-Day Health Score: Ranks your health status (S to D rank) across 5 categories: fasting, hydration, diet, bowel movements, and overall condition.
■ Manage Your Health All in One Place
・Meal Logging: Easily record what you eat by selecting from categories.
・Hydration Tracking: Log water, tea, coffee, etc., with hydration reminders.
・Wellness & Lifestyle: Track headaches, skin issues, mental state, sleep, exercise, and more to identify causes of discomfort.
・Weight & Body Fat: Monitor progress with graphs to manage your diet.
【Recommended For】
・Those wanting to maximize the effects of 16-hour fasting (autophagy)
・Those troubled by unexplained discomfort like constipation, diarrhea, or skin issues
・Those wanting to know “what foods make them feel unwell”
・Those wanting to efficiently diet and improve their constitution using numbers and data
Start a new habit today: Rest your gut, get to know yourself, and regulate from within.
