A garden instead of a red number: the idea behind our gamified calorie tracker

Why do calorie trackers show a red number?

Open plenty of calorie trackers after a big dinner and you’ll meet it: a number near the top, in red. Over by 312. Nobody designed it to hurt. Trackers built around a daily budget need a way to say “you’ve passed the limit”, and red is the colour software has always used for that. It’s consistent, it’s honest about the arithmetic, and it’s easy to build.

The trouble is what red means everywhere else. Red is an error message, a failed test, an overdrawn account. Put it on a dinner and the dinner becomes a mistake. Do that a few evenings in a row and opening the app starts to feel like checking a balance you’d rather not see.

We noticed it in ourselves first. On the days we most needed a calm look at what we’d eaten, the app was at its loudest, so we looked away. Tracking stops working the moment you start hiding from it.

And the red spreads. Once it appears, a glass of water or a short walk after dinner can feel pointless, as if the day were already “lost”. But the small things you do at that hour count too.

What did we take out of Doydum?

So we took the red out. Not the numbers, just the verdict. Here’s what you won’t find in Doydum:

• No red “over” number. A fuller day looks like a day.
• No moral labels on food. A simit is a simit, and baklava at a wedding is baklava at a wedding.
• No streak that snaps after one quiet day. A day with at least one meal counts, and rain barrels cover the odd day you miss.
• No lectures. Doy never scolds and never talks about bodies.
• No wilting. Nothing on the farm dies, withers or runs away.

Writing that list, we asked one question about every screen: how does this feel the morning after a fuller day? Anything that failed that test went.

An over-target day in Doydum is ordinary. Doy stays kind and doesn’t push a suggestion. Your farm still grows from what you logged. Tomorrow is a fresh page. That’s the whole policy, and it fits on a sticky note.

How does your day grow a farm?

Instead of a verdict, you get a place. Doy lives on a little pixel farm, and what you do each day changes it in ways you can see.

The seasons and the time of day change the farm too, and Halloween and Christmas dress it up. That deserves a post of its own: Seasons on Doy’s farm. Your step target, by the way, is yours to set anywhere from 2,000 to 30,000; if you’re wondering where to put it, our guide to 10,000 steps a day can help.

Every row in that table has one thing in common: it’s about adding. Nothing on the farm is ever subtracted. Your day only shows you how much has grown.

Why a farm instead of a progress bar?

A progress bar resets every midnight. It can only be empty, partly full or full, and tomorrow it’s empty again. A farm keeps what you’ve done. Every finished week stands by the barn as a crate. Every golden day is a sunflower along the fence. The hen who was there on your first day has company now.

That matters because eating is a slow story. Habits don’t change in a day, and no single day decides much. A farm is built for that kind of time: rows take a few hours to ripen, a week fills a crate, a season changes the colours. It rewards coming back, not being perfect. Even if you only drop by now and then, there’s often something new: a row has ripened, a lamb has arrived, the season has turned. And finding last week’s crate by the barn on a Monday morning is a small, real pleasure.

It also gives a quiet day a gentle meaning. If you log nothing, today’s bed simply stays bare. Nothing is lost and nothing is punished. There’s just room to plant tomorrow.

And it’s pixel art, which helps more than you’d think. A world drawn in chunky pixels feels like a game you’d want to play, not a dashboard you have to check. Doy runs his errands, the animals wander about, and you’ll catch yourself opening the app just to see who’s down by the pond.

Can you buy animals on Doy’s farm?

No. Every animal on the farm is earned by keeping going, never bought. There’s no shop and no coins, and nothing on the farm has a price tag.

It was an easy decision. If the calf could be bought, it would mean “I paid”. Because it can’t, it means “I kept showing up”. The same goes for the rug and the sofa in Doy’s house. They arrive with your logged days, so they’re souvenirs of real days rather than purchases.

It keeps the farm honest in the other direction, too. Since nothing can be bought, nothing is taken away either. A quiet week doesn’t send the goat home. What you’ve gathered stays yours.

Does Doydum still count calories?

Yes, every one. Under the farm, Doydum is a complete calorie tracker. Each meal is logged with calories, protein, carbs and fat, whether you scan the plate, scan a barcode or type it in. Your daily target comes from the same formula as our calorie calculator, and the plan never goes below a minimum: 1,200 kcal on the female formula, 1,500 on the male.

When you want the numbers, they’re one tab away. Progress charts show calories, water, steps and weight over 7, 30 or 90 days, and a day you didn’t log shows as unlogged, never as zero. For a closer read, Doy can go through any chart with you, the way an experienced registered dietitian reads a client’s log. We wrote about that in Doy reads your week.

What changed is the order. The farm is what you see first; the numbers are what you look up. For weight especially, the trend over weeks matters, not one day. Even the classic “7,700 kcal per kilo” rule is a simplification, and real change slows over time (Hall et al., 2011). In that picture, one fuller evening is a small dot on a long line. There’s no reason to paint it red.

What can’t a garden do?

We want to be straight about this part. A farm can’t choose your food for you, and growing sunflowers isn’t a health outcome. What it can do is make the app somewhere you’re glad to open, which is where any habit starts.

It can’t replace care, either. If eating has become a source of worry, or if you’re pregnant, managing a medical condition or under 18, please talk to a doctor or a registered dietitian. Doydum is made for adults, and its plan is an estimate from a formula, not a prescription.

And if you need a break, take one. Doydum has an away mode for up to 14 days, and the farm will be right where you left it. While you’re away your streak doesn’t grow, but it doesn’t break either; it picks up where you left off. If you’re new to all this, our guide to counting calories is a calm place to start, and Why our calorie counter has a companion introduces the farm’s most important resident.
