App prototyping: test your idea before you build it
See, tap through and test your app before a single line of code is written. A prototype is the quickest way to find out what works.

Why ProductByDesign
For a smaller app, we can typically deliver a clickable prototype in two weeks. More complex apps take longer. Once we understand the features you need, we'll give you a clear timeline and quote before we start.
Prototyping lets you validate an idea cheaply. You find out what customers understand, what they ignore and what they need, before you commit to a full build.
Our fixed-price Design Sprint is the easiest way to start. If you go ahead with the build, we credit the sprint to your project.
What we design and build: New app ideas, MVPs for startups, concept validation and redesigns of existing products.
What you get from a prototype
- A clickable prototype of your key screens that runs on your phone
- User flows and wireframes for the whole product
- Testing with real customers and a summary of what they found
- A prioritised feature list for your first version
- A clear build plan with a fixed quote and timeline
- Designs you can use to pitch to investors, partners or your team
Frequently asked questions
How quickly can you build a prototype?
For a smaller app, we can typically deliver a clickable prototype in two weeks. More complex apps take longer. Once we understand the features you need, we'll give you a clear timeline and quote before we start.
How much does a prototype cost?
Our Design Sprint is a fixed $4,900 in AUD excluding GST, and it's credited to your build if you go ahead.
What is the difference between a prototype and an MVP?
A prototype is a clickable design used to test an idea. An MVP is a working first version of the product that real customers can use.
What tools do you use for prototyping?
We design and prototype in Figma, which lets you and your customers try the app on a phone or computer.
