Movement questions often arise at home, where general information can be hard to organize and source. Cost Plus PT is exploring a simpler way to review source-linked exercise information, use optional guided-session tools, and keep a personal activity log.

That product has a permanent boundary: it is self-guided education, not physical therapy or medical care. No clinician reviews or monitors a user’s account, and the app does not diagnose, prescribe, treat, medically clear, or determine whether an exercise is safe or appropriate for someone.

Start narrow and keep the limits visible

The first information topic is intentionally narrow. A smaller scope lets us test source provenance, content rendering, general stop messages, movement counting, guided sessions, and personal tracking without pretending that software can responsibly handle every condition.

Breadth is easy to promise. Reliable and truthful behavior is harder. We would rather keep the limits visible and verify one educational topic before researching the next.

Automation should make uncertainty clearer

A useful movement guide should distinguish what a person reports, what a camera can count, and what the system does not know. When the view is poor or information is incomplete, the right output is not false confidence. It is “not observed,” a retry, or a stop message.

That principle shapes the product we are prototyping. A conversational layer may help someone navigate the software, but it cannot interpret symptoms, choose treatment, provide reassurance or clearance, or quietly override fixed boundaries.

  • Show why the displayed information changed.
  • Say when a movement was not observed clearly.
  • Keep conservative stop messages outside the model’s discretion.
  • Make general seek-care information available without a paywall.

Cost plus means showing the work

Transparent pricing is only one part of the idea. We also want to be transparent about product decisions, evidence, setbacks, and what still needs to be proven. This newsletter is where those notes will live.

Cost Plus PT is currently in development. It provides self-guided movement education and personal tracking—not physical therapy, medical care, or an emergency service. No clinician reviews or monitors its use. As the product changes, we will keep that boundary—and the reasons behind it—plainly visible.
