Apple Health import

What happens

When installing the provided .ipa (sideloaded) on an iPhone, the app can be started, but importing a WHOOP export ZIP/Apple Health export.zip does not work: instead of the expected iOS file selection dialog, the Finder/an inappropriate macOS Flow opens, and the ZIP cannot be clicked on or imported.

Actual behavior:

The app appears to show the macOS file import flow (SwiftUI .fileImporter) or a non-functional picker UI; the import fails, and it is not possible to select a ZIP.

Analysis / Suspected Root Cause:

In Strand/Screens/DataSourcesView.swift, SwiftUI .fileImporter() wird in Zeile ~20 verwendet. .fileImporter is available on macOS, but the iOS target uses an iOS-specific DocumentPicker implementation (Strand/System/DocumentPicker.swift) with a UIDocumentPickerViewController.
Apparently, the iOS DocumentPicker API is not being called; instead, the macOS importer path remains active, which does not work correctly on iOS and leads to the described problem.

Affected Data (Pointer):

• Strand/Screens/DataSourcesView.swift — uses .fileImporter(isPresented: allowedContentTypes: allowsMultipleSelection: ...) (macOS style) and calls handleImportResult(...).

What you expected instead

• On iOS, a UIDocumentPicker/Files dialog should appear, and a ZIP file (or export.xml/folder) should be selectable. The app should then be able to read and import the file locally (as it does in the macOS workflow).

Steps to reproduce

1. Install NOOP-v-ios.ipa on an iPhone via AltStore/SideStore (or locally with a paid dev cert + profile).
2. Start the app.
3. Settings → Data Sources → Apple Health → "Choose export.zip..." (or WHOOP → "Choose export...")
4. Instead of the iOS document picker, a Finder-like UI appears and the ZIP file cannot be selected/opened; the import fails.

Strap log

Before you submit

• I attached or pasted a strap log above — or my bug is a clearly reproducible UI issue that doesn't need one (e.g. a typo, a button that does nothing) and I've described exactly how to see it.
• I checked the Troubleshooting guide — especially "history syncs but no data" (most often the strap isn't banking history to flash; charge it to 100% and reconnect).
• I've left out anything personal (strap serial, account email, raw export).

Thanks for the sharp write-up, @adrnxq — and you were right that import was broken on iOS, even if the cause turned out to be one layer over from where you pointed.

.fileImporter is actually the correct cross-platform call (it presents the iOS Files picker under the hood, not a macOS panel), so it wasn't falling through to a Mac path. The real culprit was the allowed content types: the importer offered UTType.folder alongside .zip (so a Mac user can point at an unzipped export folder). On iOS, putting .folder in that list makes the Files picker grey out the .zip — the picker opens but nothing is selectable, which is exactly what you saw.

Fixed in v2.6.3: .folder is now gated to macOS, so on iPhone the picker offers only the file types it can actually open (.zip, and .xml for Apple Health). The .zip is selectable again, and the rest of the import path (which already handles the security-scoped file read) is unchanged.

Grab the v2.6.3 .ipa from the release (or add the new AltStore source for one-tap updates) and let me know it imports for you — I'll keep this open until you confirm. Thanks again for the precise repro.

Shipped in v2.6.3 — the iOS picker no longer greys out the .zip. Closing as resolved; comment if it still won't import on v2.6.3+.

I created an export from Apple Health (164 MB), but when I try to import the export.zip file, it doesn't work.

I tried importing it from iCloud File and also after moving the file directly to my iPhone's local storage, but neither worked.

I also used Claude Code to reduce the export to only one year of data, decreasing the file size from 164 MB to 64 MB, but the import still doesn't work.

Doesn’t work for me; I’m still not able to import the files. The buttons changed, however, from "Open" to just an X

[NoopApp]

Thanks both — and apologies, I closed this too early. The v2.6.3 change only fixed half of it (it un-greyed the .zip so the picker would let you select it — which matches what @adrnxq saw, the buttons changing). The actual import then still failed, which I missed because I can't reproduce it on a real sideloaded device here. That's on me.

Here's what I think was going wrong, now fixed in v2.6.8:

NOOP was handing the file you picked straight to the zip reader in place. On iPhone that breaks in two common cases:

• iCloud Drive files (@Chopin85 — you mentioned iCloud): the file you pick is often just a placeholder that hasn't actually downloaded yet, so opening it fails.
• Large exports and the sandboxed file-access timing on a sideloaded build.

v2.6.8 now copies the file you pick into the app's own storage first (properly coordinating the read, which forces an iCloud file to download), and only then imports it — streaming it so even a multi-hundred-MB Apple Health export is fine. A 64–164 MB export should import now.

Could you both grab v2.6.8 (release here, or via the AltStore source) and try again?

If it still fails, the exact error text is what I need. After you pick the file, the WHOOP / Apple Health card shows a red "Import failed: …" line — please paste whatever comes after "Import failed:". That message pinpoints exactly where it's breaking. (If instead the app just closes during import, tell me that — it'd mean something different.)

Keeping this open until one of you confirms it works. 🙏
