LAM Companion, a rare-disease tracker that knows what a trough level is

Field notes

LAM Companion organizes rare-disease records around the details generic health trackers tend to omit: sirolimus schedules, trough-level dates, PFTs, kidney monitoring, and multiple specialist visits. Users can enter historical results with their original dates, then produce an emergency card or doctor-ready report. The homepage describes two onboarding routes—one gradual for newly diagnosed users and one faster for people already managing LAM—and says the app stores data on the phone rather than requiring an account.
