Dashboard — remaining protein

PKU Diet tracks protein intake from food, in grams, against a daily limit. You can also record blood-test Phe results in µmol/L.

What it does

Everyday PKU tracking, together

Log food against a personal limit, keep meals and pantry in one place, and share a profile with the people who help. How sharing works

Tracking

See remaining protein for the day, log meals by type, and keep a home-screen widget on the fridge door.

The dashboard shows what is left after food and reserved supplement protein. Swipe days, copy yesterday, and log by weight or by the protein you wanted to use.

Meals

Save meals with ingredients and notes, scale a portion, and turn a week plan into a shopping list.

Build a meal once — household measures plus grams — then apply it at 25–200% or log leftovers. Plan the week if you want a list for the shop.

Saved meals

Care and clinic

Medications, supplements, optional blood-test results, sick days, insights, and a PDF or CSV for clinic.

Supplements reserve protein in the food budget. You can also log blood tests (Phe in µmol/L). Insights and export are for the conversation with clinic — not a diagnosis.

For the whole family

Several people, one shared picture

PKU is rarely a one-person job. Keep more than one profile on your account, then invite family with a code or QR so everyone sees the same remaining protein, pantry, and shopping list.

Profile sharing
Pantry stock

  • Multiple profiles

    One signed-in account can look after several people. Each profile has their own name, daily protein limit, and log — so you can switch between a child, a partner, or yourself without mixing the numbers.

  • Share with family

    Invite parents, a partner, or grandparents with an 8-character share code or a QR. They join that profile and see the same remaining protein, food log, and reminders. Only share a code with people you trust.

  • Shared pantry

    Stock, units, low-stock minimums, and expiry sit on the profile — not on one person’s phone. Anyone who has joined can scan to add or subtract, so the cupboard stays in sync.

  • Shopping lists

    Turn low stock or a week plan into a daily, weekly, or monthly list. Tick items off at the shop, record how much you bought, and add it back to the shared pantry.

How it works

Three steps, then you’re tracking

  1. 1

    Create a profile

    Set a daily protein limit for the person you care for — or for yourself.

  2. 2

    Log food or apply a meal

    Search, scan a barcode, or drop in a saved meal and scale the portion.

  3. 3

    See what’s left

    Watch remaining protein through the day, then share or export for clinic.

The story

Made for families like ours

This application was made because my daughter has PKU. I built it so families like ours can track protein, meals, medications, and day-to-day care in one place.

I am happy to take developer requests — if a feature would help your PKU routine, email me.
