A Goniometer Pro PDF report: clinic letterhead and a range-of-motion results table with left and right sides, ROM, AAOS normal values, and percent-of-normal columns

A real Pro report

This is an actual export from the app — not a mockup. One tap produces a document you can drop straight into your notes.

  • Your clinic's letterheadPractice name and logo on page one — reports look like they came from your clinic, because they did.
  • Progress charted across visitsEvery reading is kept with its date. Trend charts are drawn automatically against AAOS normal values — proof of outcomes, not just numbers.
  • Clinical summary, computed for youTotal Active Motion (TAM) per finger and side-to-side comparison against the patient's own contralateral limb.
  • Watermark-free PDF & CSVFree exports carry a watermark. Pro reports are clean, complete, and ready to file or share.

Progress you can prove

Page two of the same report. Every saved reading is plotted across visits against the AAOS normal, with the patient's goal drawn as a target line on the chart — automatically, no charting on your part. The header does the talking at a re-evaluation: since first reading, L +37°.
