What it doesOn-device only

Six things, done carefully.

01 / PinPoint
Injection & ancillary logs

Record injections (compound, ester, dose, site, timestamp) and ancillary medications — anastrozole, hCG, DHEA, finasteride, and others — in a single timeline.

02 / PinPoint
Lab tracking

Total T, Free T, Estradiol, Hematocrit, Hemoglobin, PSA and more, charted over time. Reference ranges are user-editable, because labs are not.

03 / PinPoint
Serum level estimates

A pharmacokinetic model, calibrated to your protocol, visualizes estimated serum testosterone between blood draws so you can see the shape of your week.

04 / PinPoint
Symptoms & body metrics

Track symptoms and body metrics — weight, body fat %, blood pressure — manually, or sync with Apple HealthKit when you grant permission.

05 / PinPoint
Dose reminders

Optional local notifications keep your injection schedule on track. Reminders are scheduled on-device; no content ever leaves the phone.

06 / PinPoint
Export & delete

Export your full data archive at any time. Delete every record with a single tap. Your data, your decision.

Who it's forPatients, not athletes

For men already prescribed TRT.

Who it's for
People who want their protocol in one place.

PinPoint is built for patients already prescribed TRT who want a private, on-device way to keep their dosing schedule, lab work, and symptoms together — and to walk into their next appointment with a clean report for their prescribing physician.

What it isn't
Not a coach. Not a medical device.

PinPoint does not diagnose, treat, or recommend dosages. It does not support cycling, stacking, or non-TRT compounds. It is not a replacement for medical care — your prescribing physician is.
