Eight weeks of guesswork,
finally written down.

Your vet asks how the diet is going. TailTrials makes sure you have an answer — every day logged, charted, and ready to hand over.

A two-minute look at how a trial runs, start to finish.

How it works

A diet trial has three phases. Most apps only handle the first.

TailTrials follows the whole thing — including reintroduction, which is where months of careful work usually get lost.

Weeks 1–8

Elimination

One novel diet, nothing else. You log what they ate, whether you stayed on plan, and how bad the itching was. About twenty seconds.

Weeks 8–12

Reintroduction

Foods go back one at a time. Each addition is dated, each reaction lines up against it, so the culprit is obvious instead of guessed at.

Ongoing

Maintenance

You know what to avoid. Keep logging lightly, and start a fresh trial any time without losing the old record.

What's in it

Built for the bit everyone finds hard: remembering.

Twenty-second daily log

Diet, compliance, itch score. One screen, no menus to dig through — because a log you dread is a log you abandon.

Itchiness trend chart

Day to day, improvement is invisible. The chart shows the direction your memory can't — including when it's flat.

Vet-ready PDF

Every day in order, the chart, and every diet or phase change marked. Email it before the appointment or hand it over at the desk.

Honest slip-up tracking

One question a day: did you stay on the diet? A slip-up you wrote down is data. One you forgot is why trials get thrown out.

Backdating and edits

Missed a couple of days? Pick the date and fill them in. Fix any entry you got wrong. Missing a day shouldn't end the trial.

More than one pet

Each animal gets its own trial, timeline, diet and chart. One PDF each, so nobody's record gets mixed up at the vet.

Pricing

$4.99. That's the whole thing.

Guides — coming soon

What actually happens during a diet trial.

Plain-language guides for the eight to twelve weeks you're about to spend reading ingredient labels.

Getting started

How long does an elimination diet actually take?

Why eight weeks is the floor, not the target, and what to expect month by month.

Reintroduction

Five mistakes people make reintroducing food

Going too fast is the common one. The others are harder to spot and just as costly.

What your vet actually needs from you

TailTrials is a record-keeping tool, not a medical one. It doesn't diagnose, treat, or recommend diets. Elimination trials should be planned and interpreted by your veterinarian — TailTrials just makes sure they get an accurate record of what happened.
