A Kings Day marketplace companion app for the Netherlands, designed in mainly orange, with white space and black typography/icons. The app helps groups of friends shop smarter during the King’s Day vrijmarkt by letting them photograph items, share finds, reserve purchases, and split/pay back costs inside the app.
Core idea
On King’s Day, everyone walks around different markets and finds funny, useful, rare, or nostalgic second-hand items. Instead of sending messy WhatsApp photos and payment requests, Oranje Markt lets you create a shared group shopping list.
You take a photo of something you find, add the price and location, send it to your group, and friends can quickly say:
Buy it for me
Maybe
Skip
Add to group list
Then the person who buys it can mark it as bought, and the app automatically tracks who owes what.
Logo concept
The logo uses Paleis Het Loo as the main icon, simplified into a clean royal palace silhouette.
Visual direction:
Icon: Minimal line-art version of Paleis Het Loo
Color: Orange palace on white background, or white palace inside an orange circle
Accent: Small black crown or market flag above the palace
Style: Royal but playful, like a festival app, not too formal
Possible logo lockup:
[Paleis Het Loo icon] Oranje Markt
Tagline: Find it. Share it. Split it.
Visual identity
The app should feel festive, Dutch, and easy to use outdoors.

Key features
1. Snap a market find
A user sees an item at the King’s Day market and takes a picture inside the app.
They can add:
Item name
Price
Seller/location
Condition
Deadline, for example “Need answer in 5 minutes”
Who it might be for
Example:
Vintage Ajax jacket
€12
Museumplein
“Looks good, size M. Should I buy?”
2. Share with friends
The item appears instantly in the group feed.
Friends can tap:
Buy for me
Add to shopping list
Too expensive
Offer €8
No thanks
This makes it faster than texting photos back and forth.
3. Group shopping list
Friends can create a shared list before or during King’s Day.
Example list:
Orange sunglasses
Old vinyl records
Kids’ toys
Dutch ceramic plates
Vintage sportswear
Board games
Funny home decoration
When someone finds a matching item, they attach it to the list.
4. Payback inside the app
When someone buys an item for a friend, the app automatically records the debt.
Example:
Sanne buys a lamp for Daan: €7
Daan owes Sanne: €7
At the end of the day, the app calculates the total balance between friends.
So instead of ten separate payments, it can say:
Daan pays Sanne €21.50
Mila pays Daan €8
Tom pays Mila €14
5. Pay for one item or a whole list
The app supports two payment modes:
Single item payment
A friend pays back for one bought item.
Whole shopping list payment
A friend pays for everything bought for them during the day in one final payment.
Example:
Items bought for Noor
Orange jacket — €10
Ceramic vase — €6
Board game — €4
Total: €20
Button: Pay Noor’s list
6. Location-based market map
A simple map shows where friends found items.
Possible markets:
Amsterdam
Utrecht
Rotterdam
The Hague
Eindhoven
Groningen
Local neighborhood markets
Pins can show:
Photo of item
Price
Who found it
Whether it was bought or still available
7. Fast “King’s Day mode”
Because people are outside, walking, drinking, bargaining, and dealing with crowds, the interface should be extremely simple.
Big buttons.
High contrast.
Minimal typing.
Fast camera access.
One-tap approval.
Easy payment summary.
