About This Site

Wound7 Wound Tracker — a companion for doctor–patient communication. Record wound changes on your phone and present them in full to your medical team at follow-up visits.

Easy Recording, Simple Operation

• Create a folder for each case (yourself or a family member), named by nickname — no real names needed.
• Take a photo or add from the album; photos are automatically arranged by date.
• Check symptoms (exudate, redness, odor…) and treatments (dressing, debridement, antibiotics…) — multi-select supported.

Data Security, Fully Offline

• No accounts, no cloud, no ads — the app never connects to the internet to collect data.
• The database is encrypted with military-grade encryption stored on the phone; exported photos automatically strip GPS and device metadata.

Safe Exchange & Backup

• Export an "encrypted package" to a USB drive: migrating to a new phone, handing to a clinician with the app installed — viewable within the app.
• Export a "plain viewing package" to a USB drive: back up to a computer; clinicians without the app can also receive and view it on a computer.
• iPhone ↔ Android, cross-platform interoperability; export and import individually, in multiple, or in batch.

Built-in Wound Care Guidelines

• Synced with wound7.com evidence-based wound care guidelines: healing principles, acute & chronic wounds, dressing selection, infection warning signs.
• Switch between Traditional Chinese, English, and Simplified Chinese — content fully readable offline.

⚠ This app is a recording and educational tool. It does not provide diagnosis. Seek medical attention promptly if a wound worsens.

Before you start: ① USB drive — a USB-C drive plugs directly into the USB-C port at the bottom of an iPhone/Android phone; older USB-A drives need a USB-A to USB-C adapter. ② Recommended format: exFAT or FAT32 (readable on both Mac and Windows). Plug the drive into the phone's USB-C port, ③ open the app and tap "Tracking" at the bottom to get ready to transfer case photos.

1. Export/Upload (save case photos to the USB drive): ① open the app and tap "Tracking" ② tap the export icon (⬆️) on the right of the case to export, or tap the "Batch export (☑)" button to export one, multiple, or a batch of packages. ③ Choose a format: encrypted package (.woundpkg) = photos + full records, requires a password (easy-to-remember digits), the clinician's phone must have the app installed to import it; best for formal exchange and backup; plain viewing package (ZIP) = photos + PDF summary, NOT encrypted (requires ticking the unencrypted-risk option), viewable on any computer; for clinicians without the app, also suitable for copying and storing on a computer. ④ if you chose the encrypted package, the "Package password" page appears — enter and set a password (easy-to-remember digits are fine) ⑤ on the share sheet, tap "Save to Files" ⑥ when the USB drive's storage page appears, tap "Save" to export (upload) the case photos ⑦ after the upload finishes, the "Case photos uploaded" page appears — tap "Confirm" ⑧ close the app before unplugging the drive.

2. Import/Download (import case photos from the USB drive): ① plug the drive containing the encrypted package into the phone, open the app, tap "Tracking", then tap the import icon (⬇️) at the top right ② when the drive's storage page appears, "select" the .woundpkg package to import (iPhone), or "long-press" the first package to import (Android); you can import one, multiple, or a batch of packages. ③ when the "Package password" page appears, enter the password set at export, tap "Open" (iPhone) or "Select" (Android) at the top right, then tap "Confirm" (batch import results) to import one, multiple, or a batch of case photos ④ the app verifies package integrity (8 checks); once passed it is imported as a NEW case — existing case photos are never overwritten ⑤ after the download finishes, the "Case photos downloaded" page appears — tap "Confirm" ⑥ the imported case then appears in the case list with all photos and records ⑦ close the app before unplugging the drive.

3. Notes: ① for formal exchange use the encrypted package (.woundpkg); the plain viewing package (ZIP) is NOT encrypted — anyone can view the photos if the drive is lost. ② remember your password: a forgotten password means the encrypted package cannot be opened (no backdoor); easy-to-remember digits are fine. ③ cases are named by nickname with no real names or identifiers; exported photos have phone info (EXIF) and GPS location automatically removed. ④ re-importing the same encrypted package is detected to avoid duplicate cases. ⑤ moving to a new phone, transfer photos between the old and new phone's "app": export an "encrypted package (.woundpkg)" on the old phone's app to the drive, then import the "encrypted package (.woundpkg)" from the drive on the new phone's app — done. ⑥ backing up photos to a computer, transfer photos between the phone's "app" and a computer: export a "plain viewing package (ZIP)" on the phone's app to the drive, then import the "plain viewing package (ZIP)" from the drive to the computer — done.
