AI Fatty Liver Companion · Understand your labs · Track what you do · Prep for your doctor
Hepatica helps you understand and follow your own liver-health information:
No. Hepatica is a Health & Fitness wellness companion, not a medical device. It does not diagnose, treat, cure, or prevent any condition. Always consult your doctor or hepatologist before starting, changing, or stopping any treatment. See the Medical Disclaimer.
No. Hepatica cannot diagnose NAFLD, MASLD, NASH/MASH, fibrosis, or cirrhosis. It explains what your lab values mean against the reference range on your report and helps you follow them over time — a diagnosis can only come from a qualified doctor who sees your full clinical picture. A value outside the range means "discuss this with your doctor", not "you have a disease".
Open Labs and scan a report, choose a PDF, or enter the values by hand. For a photo or PDF, the image (for a PDF, up to its first three pages) is sent to our AI service to read the test names, values, units, reference ranges and date. You then check and correct every value before saving. Hepatica explains each saved value against the reference range printed on your own report and shows how it compares with your previous test. The report photo or PDF itself is not saved in the App — only the values you confirm. Manual entry needs no AI and no internet.
Lab reports can show personal identifiers. A scanned page is sent over an encrypted connection only to read the results, and the AI provider processes it under its service terms. You are welcome to crop or cover your name and other identifiers before scanning — the App only needs the test names, numbers, units and ranges. Or type the values in yourself. See the Privacy Policy §2.1.
FIB-4 is a published screening index calculated from age, AST, ALT and platelet count. Hepatica calculates it on your device once those values are available. It is shown for education and to help you talk with your doctor — it does not stage fibrosis and is not a diagnosis. It is only as accurate as the values you saved.
Take or choose a photo of your meal on the scan screen. Hepatica reads it right away and returns an educational liver-friendliness score from 0 to 100, shown in three bands (Liver-friendly, Go easy, Tough on your liver), with what in the meal helps, what to go easy on, and one practical swap. It is general dietary education, not a meal plan or a prediction about your liver. You choose whether to save the meal to your log.
Before rating, the AI checks whether the photo shows food or drink. If it doesn't — for example a screenshot, a document or a room — Hepatica says it doesn't look like a meal and gives no score. That photo is not saved and not counted. Try again with the whole plate from above, in good light, one meal per photo. You can also log the meal by hand.
The Coach answers using excerpts from a source collection bundled with the App — published guidelines, public health sources and research (for example AASLD, AGA, EASL, NIH/NIDDK, NIAAA, MedlinePlus, NHS, FDA drug labels and PubMed). When an answer uses sources, they are shown with it; everyday conversation may not need one. Answers are generated by AI, are educational, and can be incomplete or wrong — check anything important with your doctor.
No. Safety checks on your device recognise questions about diagnosis, medicine doses or stopping a medicine, and messages that mention a crisis, alcohol withdrawal or possible emergency symptoms. Instead of an AI answer, you get a redirect to your clinician or to emergency and crisis resources. Never start, stop, or change a prescribed medication based on the App.
You can record drinks and alcohol-free days. If you'd rather not see alcohol in Progress, you can hide it, and you choose whether alcohol records are included in the doctor summary. It is a personal-awareness tool, offered without judgement — not treatment for alcohol use disorder. Important: do not stop heavy or daily drinking abruptly without medical advice, because withdrawal can be dangerous. See the Medical Disclaimer §9.
Evening check-ins, weekly goals, medicines from the catalog and whether you took each dose, weight, symptoms with severity and an optional note, and period start dates. History can be filtered by type. Reminders are local notifications you set in Settings → Notifications.
No. Hepatica does not read from or write to Apple Health. Everything you track is entered in the App.
Your labs, meals, check-ins, medicines, alcohol records, weight, symptoms and Coach conversations are stored locally on your device. No account is needed. After your consent, a meal photo, lab report page or Coach question — with the record context described in the Privacy Policy — is sent through our AI service only when you tap to analyze or send. AI providers process that content under their service terms. There are no ads, no advertising or tracking SDKs, and no analytics sent to our servers. See the full Privacy Policy.
Go to Settings → Data & privacy and turn off Send photos and messages for AI analysis. With it off, no photos, PDFs or questions are sent to any AI service. You can keep using Hepatica as a tracker — manual lab entry, logs, check-ins, FIB-4, reminders and the doctor summary work without it. Turn it back on any time.
If your App Store storefront or device region is mainland China, AI requests go to Qwen through our Alibaba Cloud service in mainland China, with no fallback to other services. Everywhere else, they go through our Cloudflare service to OpenAI, DeepSeek and TypeSafe. App language does not change this. Details are in the Privacy Policy §2.
No. Meal feedback looks at food and lab reading looks at a document — Hepatica does not perform face recognition, biometric template extraction, or any facial analysis.
Both plans unlock the same Hepatica Plus features. Prices vary by region; the paywall and Apple show the exact local price and terms before you confirm. Subscriptions renew automatically unless cancelled at least 24 hours before the current period (or trial) ends.
Weekly is the low-commitment way to try Hepatica Plus, so that's where the 7-day free trial is offered. Annual already costs less per week and is billed at purchase, with no trial. The trial is an Apple introductory offer: the paywall shows it only when the App Store offers it and confirms you're eligible (for example, if you've already had it, you won't see it again). Without a trial, Weekly is charged at purchase.
iOS Settings → your name → Subscriptions → Hepatica → Cancel Subscription, or in the App: Settings → Subscription → Manage subscription. To avoid being charged, cancel at least 24 hours before the current period or trial ends; access continues until the end of the period. Deleting the App does not cancel a subscription. Refunds are handled by Apple at reportaproblem.apple.com.
If you reinstalled Hepatica or switched devices, tap Restore on the paywall, or open Settings → Subscription → Restore purchases. Make sure you are signed in to the same Apple account you used originally.
Yes. The doctor summary is a PDF created on your device with your lab results and trends, FIB-4 screening score, medicines and doses you logged, and recent tracking — you choose whether alcohol records are included. Review it, then share it through the iOS share sheet; you decide where it goes. It is your record, not a clinical report.
Your records are stored on your device. Delete individual entries in the App, or use Settings → Data & privacy → Reset app & delete all data to erase all records, saved meal photos, the local cache and scheduled reminders at once. Deleting the App also removes its local data. Copies in device backups, summaries you exported and content already processed by AI providers are separate — see the Privacy Policy §9. Your subscription stays with your Apple account.
Lab reading, meal feedback and the Coach need internet and the AI switch turned on. If a request fails, nothing you saved is lost — check your connection and try again, or enter the values or meal by hand. There is also a weekly limit on photo analyses; if you reach it, try again later or log manually.
Email sergejkar@gmail.com with: (1) your iPhone model and iOS version, (2) the Hepatica version (iOS Settings → General → iPhone Storage → Hepatica), (3) what you tapped right before the bug, (4) a screenshot if it is visual. Please don't send lab reports or other health details unless they're needed. We respond within 24 hours.
Hepatica requires iOS 17.0 or later.
Hepatica is not an emergency service. Severe upper-right abdominal pain, new or worsening jaundice (yellow skin or eyes), vomiting blood, black tarry stools, or confusion need urgent care — contact your local emergency services or go to an emergency department. See the Medical Disclaimer §10 for emergency signs and §11 for crisis lines.
