The Mello app
See who recorded the insulin, and when.
When two people share the care of a diabetic dog or cat, the thing that goes wrong is rarely a missed reading. It is a second injection, given because nobody could say for certain whether the first one happened. Mello is the shared record that answers that question.
Keeping the record, and the warning before a second dose, are free. Inviting the other people who look after your pet is part of Premium — see what each includes.
Mello is not in the app stores yet. Join the list and we will email you once — when it is there. New users get 28 days of Premium, and no card is asked for.

What it does
Know whether the dose has been given
The one question that matters at 6am, when one of you is still asleep and the other is holding a syringe. Every insulin entry shows who recorded it and when — and when nothing has been recorded, Mello says so plainly rather than implying the dose was missed.
Write it down in seconds
A reading, a meal that was refused, a dose you are not sure about. Nothing is required, so you can record only what actually happened — including a meal with no reading at all, which is how most mornings go.
Turn a fortnight into something your vet can use
A report with the events themselves: times, doses, who recorded them, and which entries were written up later from memory. Your vet can see what happened rather than being told a percentage.
Built so you can act on what it tells you
The worry with an app in the middle of your pet’s care is that it says something confident and wrong at six in the morning. Mello is built the other way round: it is exact about what happened, and it hands the judgement to the person qualified to make it.
- Dosing stays between you and your vet. Mello holds the record; it never tells you what to inject.
- When something needs attention, it gets you to your vet quickly — with the answers they are about to ask you for.
- A reading is only called high or low against the range your own vet set. Without one, Mello shows the number and says nothing about it.
Diagnosis, and advice based on it, belongs to registered vets under UK law. We think that is right, and a record your vet can read in thirty seconds is worth more at an appointment than an app with opinions.
Looking for what to do during a hypo? It is in the hypoglycaemia guide, with what has been reviewed alongside it.
Reviewed, screen by screen, by a vet in practice
In October 2026 Dr Linda Simon MVB MRCVS — a veterinary surgeon with 13 years in practice, registered with the Royal College of Veterinary Surgeons, whose declared special interests include endocrinology — went through every screen in Mello: the thresholds it acts on, the words it uses when something needs your attention, and the report it produces for your own vet.
Every recommendation she made is in the version launching in the app stores. Here is what that means when you open it.
- Before you record an injection, Mello asks whether your pet has eaten. If they have not, it tells you to speak to your vet before you inject.
- Any trace of ketones stops you and sends you to an emergency vet. You can record a urine dipstick result, not just a meter reading — most glucose meters do not measure ketones at all.
- A second dose soon after another one stops you and shows you exactly what is already on the record, and who put it there.
- The glucose ranges Mello falls back on are the goals the profession itself works to, so the percentages you see mean what a vet expects them to mean.
- Your Emergency Card dates the weight and the dose, so a vet reading it at midnight knows how current they are.
The first one came from them. Asked what owners most need prompting about, they went straight to it: giving the injection when the animal has not eaten. It is the sort of thing you only learn from somebody who sees these cases, and it is now the question Mello asks you before it saves a dose.
One clinician, once, covering the app and thirteen of the guides on this site — so we do not call Mello vet-approved, and your own vet is still the only one who has examined your animal. What she reviewed.
