About
Will it Map is the essential tool for projection mapping professionals and event technicians. Stop guessing — know where to place the projector before you set up a single cable.
How it works
Stand where your projector will be placed, open the app, and point your iPhone at the target facade. A live overlay frame shows you how large your projection will appear — in real time, on location.
Simulate any lens
Dial in throw ratios from 0.5:1 to 9:1 using intuitive sliders. Whether you're working with an ultra-short throw lens in a tight courtyard or a long-throw optic across a wide plaza, Will it Map? covers the full range of professional projection optics.
Flexible aspect ratios
Switch between 16:9, 16:10, and 4:3 to match your content format and projector specs.
Find the perfect position
Not sure where to place your projector? Walk the location with your iPhone and test different positions on the spot — no equipment needed.
Save your previews
Screenshot your simulation directly from the app to document your planning, share with clients, or compare multiple setups side by side.
Built for the real world
Whether you're planning a large-scale architectural projection, a museum installation, or a live event — Will it Map? gives you the confidence to show up on-site fully prepared.
