The blue “Windows protected your PC” message: click More info, then Run anyway. This appears only because the program is new and not yet code-signed — normal for small independent software.

If antivirus flags it: choose Allow, Keep or Restore from the antivirus notification. You can scan the installer at virustotal.com first if you prefer.

What’s inside

Everything in one place

Glucose monitoring

Log spot readings or build a full glucose curve across the day. The app draws the curve, marks the lowest point, shows feed and injection times, and lets you add a note — so an unusual reading makes sense later.

Insulin & doses

Keeps the dose your vet set safe on screen, helps with the everyday arithmetic when your dog only eats part of a meal, and puts the safety basics close at hand. It never invents or changes a dose — that is always your vet’s decision.

Diet & weight

Works out the right daily calories for your dog’s ideal weight, turns that into grams of food, and shows a food’s true fat content once the water is taken out. Includes a food list of over 160 foods. Save the plan to share with your vet.

Vet reports & backup

The Windows app produces a tidy one-button PDF for the vet — your dog’s details, weight, a glucose curve and the diet plan, all in one place. Both apps include a backup button that saves all your data to a file you can restore from on any device.

Learn

Plain-English guides covering glucose meters and sensors, what the numbers mean, exercise, diet, the eyes, urine testing and more — each with its sources listed so you can always see where the information comes from.

Support

Links to the UK Diabetic Dogs community, Blue Cross and other trusted helplines, an honest quality-of-life check, and gentle guidance for the hardest times.

The story behind it

Why this app exists

When Bryce, my 14-year-old Border Collie, was diagnosed with diabetes while we were living in Spain, the local vets had far more theoretical knowledge of the condition than practical experience. In Spain, most dogs diagnosed with diabetes are put down. I researched the subject heavily — Bryce has been doing well for the last 18 months — but it was only recently, entirely by chance, that I found the UK Diabetic Dogs community. I wished I had found them much sooner.

That experience led directly to this app: something that works offline, that puts the research I had gathered in one place, that keeps reliable records for the vet, and that might spare other owners some of the struggle I had.

About the author

After what some might call an unusual life, I found Bryce at a rescue centre on completing my circumnavigation in a 10-metre yacht. Soon bored with retirement, I became a chocolatier — and that led, unexpectedly, to learning how to build software using AI for the coding, including the production-management program on this website, which was first built for my daughter’s organic skincare business earthbound.co.uk. I’ve also written my circumnavigation account (Chasing the Sunset) and a memoir (Slightly off Script). Now in my 81st year, I still have a number of projects to complete.

Built to be trusted

Sources, not guesswork

Because real owners use it to make real decisions, everything in the app is sourced — from veterinary journals, manufacturer datasheets and professional guidelines. The sources are gathered together on a dedicated page inside the app so you can check them any time. The app records and explains; it never invents insulin doses or tells you to change what your vet has set.
