Our Story

Built from
personal need.

Not a startup. Not a business plan. Built on weekends, for real patients — starting with two.

01

My own HRT journey

I needed a reliable way to track my own hormone medications — doses, timing, long-term history — without relying on paper or generic reminder apps.

02

Caring for my wife

My wife is a kidney transplant patient with a complex, ever-changing regimen — plus dialysis beforehand. Managing Tacrolimus, Mycophenolate, and dialysis sessions daily demanded something much smarter than memory.

03

A community without resources

The HRT community in Vietnam has limited access to reliable medical information. I built a medically-cited reference library — accessible, honest, and safe.

Dose Diary is not a startup product or a business plan. It started as a deeply personal tool — built on weekends, refined through real daily use by me and my wife.

Over time, I realized many others face the same challenges — people on HRT, kidney patients tracking dialysis, caregivers managing medications for loved ones. So I opened it up, added an HRT reference library with medically-cited sources, built a full Kidney Mode, and made it free.

If this app helps even one person stay consistent with their treatment — that's everything.

Tips for better tracking

01
Weigh at the same time every day

Step on the scale each morning before eating or drinking. A consistent baseline gives your doctor an accurate dry-weight reference and makes UF volume calculations reliable across sessions.

02
Log BP within 5 minutes of each session

Record blood pressure immediately before starting and right after finishing. Delayed readings skew your 90-day trend and can mask hypotension episodes that matter to your nephrologist.

03
Review your report the night before appointments

Open your 30-day analytics before any doctor visit. Adherence rate, missed doses, and BP range tell a clear story — no more trying to recall details from memory under pressure.

04
Set refill alerts 7 days early

Enable stock tracking and trigger the alert a week before running out — not 1 or 2 days. Pharmacies run out, weekends delay orders, and missing a dose of Tacrolimus or Mycophenolate has real consequences.
