HealthFactory

Help

The most common pitfalls, with fixes. If nothing helps: in the app, gear icon → Send feedback (with a screenshot; app version and sync state are included), or email [email missing].

Setup

The Health dialog hangs or I can't find "Allow"

Tap Turn On All at the top of the dialog, then scroll all the way down: the Allow button is at the end of the long list. If Apple asks for a time range, choose all data, not just the last 30 days. If the "Health access" screen stays for more than half a minute, close and reopen the app. You can also skip and allow access later (Health → profile picture → Apps → HealthFactory).

I only allowed 30 days or too little the first time

Health → profile picture → Apps → HealthFactory: Turn On All and, if a time range is offered, all data. Then in the app: gear icon on Today → Settings → Resync all data. If that doesn't work, delete and reinstall the app; sign in to your account with Apple, passkey or email code and access is requested again.

Data is missing or there are gaps

Check in Health → profile picture → Apps → HealthFactory that all categories are on. During the first sync, keep the app open and the iPhone unlocked. Status and gaps are shown behind the gear icon on "Today". No data in a group means either "not measured" or "not allowed"; the app cannot tell the difference. More: Set up Apple Health.

Account and sign-in

New iPhone or app reinstalled

Without a secured account, a reinstall starts with an empty account. Secure your account first: in the app tap Secure account with Apple, email or passkey. On the new iPhone choose I already have an account and sign in.

Connecting Claude or ChatGPT

How do I connect Claude?

Copy the address https://selflens.app/mcp, add it in Claude under Settings → Connectors as a custom connector and tap Connect. Claude shows a code and "Open HealthFactory"; confirm the code in the app with Face ID.

Claude doesn't know a new feature

New features are available in new chats automatically. An existing chat keeps the tool list from its start. If a new chat doesn't help, disconnect and reconnect the connector in Claude.

Where can I see what Claude logged?

Symptoms and meds & supplements under Records, lab results under Records → Lab, exercises under Training → Exercises, goals and self-experiments on Today. You can delete entries there too. Weight, waist, blood pressure and mood go to Apple Health and appear under History. HealthFactory does not log food: use your nutrition app, it writes to Apple Health.

The app

Where is what?
Adding lab results (photo or PDF)

Records → Lab → +, then one of:

The app reads test name, value, unit, reference range and sample date on the iPhone; it does not read your name, date of birth or address. On the review screen you compare each value with the report, correct it or swipe wrongly recognized rows away; only Save transfers the numbers. Photos and PDFs are not stored or uploaded. You can also send Claude a photo or PDF and let it log the values.

Logging exercises (sets, reps, weights)

Health only knows the type, duration and heart rate of strength training. Sets, reps and weights go into HealthFactory: Training → Exercises → +, via Log exercises on a workout's detail page, or by telling Claude (“Today bench press 3 × 8 at 80 kg, effort 7”). Claude can also import an export from a training app this way.

Matching with the watch recording: every session has a start time. If Health has a workout that starts within 30 minutes of it or contains it, the exercises belong to that workout: duration and heart rate from the watch, sets from you, counted once. From the detail page the link is fixed. Without a recording, the session counts on its own, with the duration you give or 2.5 minutes per set. If the watch recording arrives later, it is matched automatically.

Abbreviations: RIR = reps in reserve: how many more reps you could have done before muscular failure (0 = to failure). RPE = perceived effort 1–10 (RPE 10 equals 0 RIR); for the whole session it feeds training load when there is no heart rate. ≈ or e1RM = estimated one-rep max (Epley, from the best set up to 12 reps), for comparison with yourself only. The catalog unifies exercise names (“Bankdrücken” = “Bench Press” = “BB Bench”); your own names are kept.

PDF report for your doctor or coach

On Today, tap the document icon at the top right, choose 30, 90 or 180 days, then Share PDF. The report compares the period with the equally long one before. It is created on the iPhone; you decide whom to send it to.

Pounds or kilograms, miles or kilometers

The app follows your iPhone's region. To change: Today → gear → Settings → Units (Automatic, Metric, US or UK). Data is always stored in metric; Claude converts when needed.

Language

The app is available in English and German and follows your iPhone's language (other languages show English). To change it for HealthFactory only: iPhone Settings → Apps → HealthFactory → Language.

Delete account and all data

Gear icon on Today → Settings → Delete account. You can export all data first (Export all data, same place).

No diagnoses, no ads, no selling of data. Home
