Goshi Health

Goshi Health is an intermittent fasting app for iPhone. Unlike a simple timer, it estimates which metabolic phase your body is in while you fast, using your own fasting history, and keeps you company with an avatar that mirrors your day.

HOW METABOLIC TRACKING WORKS
The app tracks 6 metabolic phases during a fast (from fed state to deep ketosis and autophagy), with a ketone (BHB) and glucose estimate based on elapsed time and your history. These are physiological estimates, not real blood measurements: they don't replace clinical testing.

YOUR AVATAR
A personal avatar that mirrors your body and your day: your fast, your water, your mood and your energy. Talk or type to it and it logs what you tell it. It levels up, completes quests and dresses in your style. It never scolds you: if you ate a lot, it simply feels full.

FOOD ANALYSIS BY PHOTO
Snap a photo of your plate and the AI detects every food separately, with its own calories and macros. When it is not obvious how something was cooked, the app asks you to choose it (and the fat used, such as olive oil, sunflower oil or butter) so the total is right. You review and correct the result before saving it: the app never saves a value without your confirmation. You can also log by barcode, by hand or from your own recipes.

AI COACH
Talk about your fast, your food and your progress. The conversation is saved to your account, available even if you switch phones, and exportable anytime. Included in Goshi Health Pro.

BODY AND PROGRESS
Log your weight and body composition. The guided Body Check-in uses the camera to detect your pose and track your progress with before/after photos, and your achievements keep you motivated.

SHARE YOUR PROGRESS
Invite someone, like your coach or a friend, to see your progress in read-only mode. You choose who to invite and can revoke access anytime.

HYDRATION AND HABITS
100+ drinks you can log, with recommendations based on the fasting phase you're in, daily streaks, and experience levels.

CYCLE AND HEALTH
Menstrual cycle tracking is integrated with your fasting plan. You can log medical conditions to get compatibility alerts for your fasting protocol.

APPLE WATCH
Syncs heart rate, heart rate variability, activity and your fast in progress, right on your wrist.

ON-DEVICE LEARNING
From your 30th fast, the app trains a model on your own iPhone using your history: it learns your habits and personalizes predictions. That model is created and stays on your device.

PRIVACY
Your Apple Health data is processed only through Apple's framework and never leaves your iPhone for our servers. You can export all your data as CSV or JSON anytime, and deleting your account truly removes your information from our servers.

5 FASTING PLANS
From 12:12 to get started, through the classic 16:8, to the advanced OMAD (one meal a day). Each plan targets specific metabolic phases.

PLANS
The app is free to start, with no ads, and core fasting, food and body features are available without paying. Goshi Health Pro is an optional subscription that unlocks the AI coach and advanced analytics. Available in dozens of languages.

Goshi Health is not a medical device and does not provide diagnosis. It does not replace the advice of a health professional. Talk to your doctor before starting any fasting protocol, especially extended fasts, if you are pregnant or breastfeeding, or if you have a history of eating disorders, diabetes or another medical condition.
