Checked by hand: the Gluten-free filter shows “Nothing matches this filter.”, though two bakes are gluten-free. One visitor stopped there. Two found the almond and orange cake by opening its allergen notes, and neither could tell whether it is safe for coeliac disease: the notes say gluten-free and, in the same breath, that traces can’t be ruled out. The automatic check counted those two as getting through.
Stuck. None found a treat they could be sure of.

Simulated visitors are a first pass. They find broken paths, dead ends and confusing labels. They are more patient and more literal than people, so they can’t tell you how your app feels to use. For that, you need real people.

The Ingredients and allergens section calls the cake gluten-free but says wheat traces cannot be ruled out, so I can't tell whether it's safe for coeliac disease.

What the visitors were asked
You have coeliac disease, so you can't eat anything with gluten in it. You'll walk past this bakery tomorrow and would love a treat. Find out whether they have anything you could eat, and say what it is.
Who: Diagnosed with coeliac disease three years ago. Checks every label, and is used to bakeries having nothing for them. Looking on their phone on the way home.
Their answer: The menu’s gluten-free filter shows no matching items, so I couldn’t find a gluten-free treat.
Step 1 · /demo/
Tapped “Menu”
“I’ll check the menu for something gluten-free.”
Step 2 · /demo/menu/
Tapped “Gluten-free”
“There’s a gluten-free filter, so I’ll see what it shows.”
Step 3 · /demo/menu/?c=gluten-free
Said they were done
The Gluten-free filter shows no matching items; I expected to see any gluten-free treats available.
Who: Coeliac for most of their life, reads ingredient lists closely and distrusts vague claims. At a desktop at work, with a few minutes to spare.
Their answer: No coeliac-safe treat is confirmed. The gluten-free filter returns no items; the almond and orange cake is made without wheat, rye or barley but may contain wheat traces. Ask the bakery about cross-contact before eating it.

Step 3 · /demo/item/?id=almond-orange-cake
Clicked “Menu”
“The almond and orange cake is made without wheat, rye or barley, but possible wheat traces make it uncertain for coeliac disease. I'll check the menu for other options.”

Said they were done
The Gluten-free filter shows no matches; I expected it to identify any suitable options.
Who: Parent of a ten-year-old who was diagnosed with coeliac disease last month; still learning what to look for. Browsing on a tablet.
Their answer: The almond and orange cake (£3.80 a slice) is made without wheat, rye or barley, but the bakery cannot rule out traces of wheat flour. Its safety for coeliac disease is therefore not assured; ask at the counter before eating it.
