Two things FL work has surfaced: (1) foot care is for far more people than diabetics — including athletes — and (2) the real product is not local storage, it's the owned, portable, longitudinal record. Companion to Foot-Risk-Beyond-Diabetes.md.
The at-risk foot has a second, huge, motivated population that has nothing to do with disease: athletes, for whom the foot is the instrument, and a small foot problem is a performance problem.

runners, soldiers, and cleated sports; painful enough to stop training.
driven, and a gateway to infection if mismanaged.
Morton's neuroma, metatarsalgia — repetitive-load injuries that end seasons.
The athlete's motive is different — protect performance, not prevent amputation — but the loop is identical: photograph the foot regularly, detect change early, catch the hot-spot before it's a blister, the blister before it's an ulcer, the ache before it's a stress fracture. An athlete will do a daily foot check for the same reason they track sleep and macros: marginal gains and staying available. That's a large, self-motivated, non-clinical adoption wedge — and it normalizes the exact behavior the high-risk diabetic patient also needs.
The insensate diabetic foot and the pounded marathoner's foot are the same monitoring problem from opposite ends: one can't feel the damage, the other can't afford it.
The AI observation is a feature. The passport is the product. Here's why the durable value is the record, not the storage or the model.
In a single year the typical Medicare patient sees two primary-care physicians and five specialists across four different practices — with no one provider holding the whole picture. Fragmented records drive medication errors, redundant tests, and delays; patients with 5+ chronic conditions account for >90% of Medicare spending, and fragmentation is a big reason why.
For a foot specifically, you're seen by primary + endocrinologist + podiatrist — each on a thin 15-minute slice, weeks or months apart, each looking at the foot today with no continuous view. Nobody in the system owns the longitudinal foot record. Except you — if you build it.

foot after that. The story is only legible if it's continuous.
any single provider relationship. That is patient-owned continuity of care, and continuity is associated with lower cost, fewer redundant tests, and more prevention.
You cannot detect change without a fixed reference. The baseline is the permanent anatomical zero-point — this foot's normal, its scars, its prior surgeries, its landmarks. Every future "appears more red than before" is measured against it. No baseline, no change detection — just disconnected snapshots.
The profile is the why and the context that makes an observation mean something. The same red patch is "expected callus" on a runner and "watch for breakdown" on an insensate diabetic foot. The profile is what lets the system — and the next clinician — interpret a finding instead of just listing it. It also carries the reason you're doing this at all, which is what keeps the habit alive.
Instead of "it looked worse last week," you hand the podiatrist a 90-day timeline — dated photos, tracked observations, a clean exportable record. The visit stops being a cold read and becomes a review of evidence. You walk in with the continuity the fragmented system can't provide, and the specialist's scarce minutes go to judgment, not reconstruction.

Software you own, on a box you own, building a record you own — that a clinician can read in minutes when it matters. That's the product. The foot is just where we start.
