What the diary does
- Record glucose readings tagged fasting, before a meal, 2 hours after a meal, bedtime or random — with an optional comment.
- Work in mmol/L (the Australian standard) or switch the display to mg/dL if that's what you're used to.
- See your trend chart with the general guide lines, plus your fasting and after-meal averages — shown for context only, never as medical advice.
- Download a PDF report or a spreadsheet whenever you choose, for the period you choose.
Adding a reading takes about ten seconds, meal timing included.
A blood sugar app that works in your browser
No app store, no password: open healthdiary.au in Safari or Chrome, sign in with your email, and it behaves like a glucose tracker app — you can add it to your home screen so it opens with one tap. Being a website, it's always up to date and identical on iPhone, Android and computer.
A report built around meal timing
The PDF report groups your readings the way clinicians think about them: your fasting, after-meal and overall averages; your highest and lowest readings with dates, in both units; how many fasting readings fell within the general 4–7 guide and how many after-meal readings were below 10; a table by time of reading; a trend chart with the guide lines; and the full record with meal timing on every row. You print it or email it to the practice yourself.
The guide values and counts are general reference points, shown to help the conversation at your appointment — they are not alerts, interpretations or personal targets. Your own goals are set by your doctor.
You choose the period the report covers — the last two weeks, 30 or 90 days, or everything. Your diary always keeps every reading.
Your averages by meal timing — illustrative numbers.
Why meal timing matters
A reading before breakfast and a reading after dinner tell your doctor different things — a number without its context is hard to use. Every entry in the diary carries its timing (fasting, before a meal, 2 hours after a meal, bedtime or random), so your report can separate fasting averages from after-meal averages automatically, the way clinicians actually read them.
mmol/L or mg/dL — use what you know
Australian meters read in mmol/L, and that's the diary's standard. If you're used to mg/dL from overseas, switch the display with one tap and enter readings that way — the diary converts them, your doctor's report stays in mmol/L, and the spreadsheet export includes both columns so nothing is ever ambiguous.
What this diary deliberately doesn't do
- It doesn't connect to your meter — you type the number in, which takes about ten seconds including the meal timing.
- It doesn't interpret your readings, adjust targets, or give dosing or treatment advice — that's your doctor's job, with your report in hand.
- It doesn't alert anyone. Nobody monitors what you record.

Common questions
What do I need to sign up?
Just a working email address. We don't ask for your name, date of birth or phone number.
Can my doctor or diabetes educator see my readings?
No — only you can see your diary. When you want them to see your readings, download a report and bring or send it yourself.
Which units does it use?
Readings are stored in mmol/L, the Australian standard. If you're used to mg/dL, switch the display with one tap — the report your doctor receives stays in mmol/L, and the spreadsheet includes both.
Does it connect to my glucose meter?
Not currently — you type in the number your meter shows, which takes about ten seconds with the meal context included.
Can I keep my medication list here too?
Yes. The same sign-in gives you a medication list: the medicines you take, in your own words, with a one-page PDF to hand to your doctor and optional email reminders for medicines you take weekly or less often, or for an injection or appointment date.
Does it work on my phone?
Yes — it runs in the browser on any device, and you can add it to your home screen so it opens like an app.
