Rank Projects with AI
A second opinion on every design
After the deadline, the AI scores every design against your brief (idea, aesthetics, practicality, buildability, graphics) and writes a note on each one. Use its order, change it or ignore it: it's only a suggestion, and you decide.
Designers stay anonymous while you judge: you see arc numbers until the final ranking.
Countdown widget
Your competition, ticking on your nightstand
A live countdown that ticks every second, with how many designs are in. It shows in StandBy while your iPhone charges.

iPhone Duo and foldables
More room when you open it up
Open your iPhone Duo and Explore spreads out in tiles. Half open, it becomes a design desk: the design up top, every entry below, ready to score. On Android, foldables and tablets get the same desk.

Questions
SpaceApp, in short
What is SpaceApp?
SpaceApp is the app of Arcbazar, a design competition platform with a worldwide community of architects and interior designers. You describe your space, set an award, and designers compete to design it. You compare the designs and pick the winner.
What kinds of projects can I start?
Home & Garden, Commercial or Institutional projects: kitchens, whole houses, gardens, remodels, shops, restaurants, offices, schools and more.
How does a design competition work?
Answer a few questions and add photos of your space, and SpaceApp drafts the brief. You see what similar competitions awarded, set your award and launch on arcbazar.com. Designers send their designs before the deadline and ask questions on the Wall. You rate and rank the designs and choose your winners.
Where do I pay?
Competitions are run and paid on arcbazar.com, which opens inside the app. There are no in-app purchases.
What is Rank Projects with AI?
After the deadline, an AI scores every design against your brief and writes a note on each one. It is only a suggestion: you can follow it, change it or ignore it.
Do I see who the designers are?
While you judge, designs are shown by arc number only, so every design is judged on its own merits. Designers' names appear with the final ranking.
Which phones does SpaceApp work on?
iPhone, including iPhone Duo open and half open, and Android phones, tablets and foldables.
I'm an architect or designer. What's in it for me?
Every running competition with its award, deadline, brief and the client's files; the Wall to ask the client questions; your entries and results; your earnings; and the Open Studio, where you see which clients are on the app and can say hello.
Let's beautify the world together, one project at a time.
