What it does

We've all had to stare at a blank page to figure out what to build. This stops now. Tinder-style. Spark is a free tool that gives you inspirations on what app to build, inspired by proven successful product launches. It provides a niche, uncovers untapped markets for each product, and so much more. It is also 100% free and no sign up required!
