For anyone about to build an app
Find out if your app will sell. Before you build it.
Describe your idea. We build the landing page, the funnel and the ads, then put them in front of strangers who have never heard of you. In a few days you get one answer: build it or don’t.
No code. About $50 of ads. One-time licence at $149, never a subscription.
After 520 visitors, the answer
BUILD IT
3.46%
3.46% of visitors picked a plan and confirmed at your price. Above 2% means people will pay for this. Go build it.

Describe the app the way you'd describe it to a friend. That's the whole input.
We build the test
A funnel carrying the price you'd actually charge, ads you can run today, and a tracked link for each one.
Strangers decide
We count who picked a plan and confirmed, then tell you in two words whether to build it.

Drag the traffic. Watch the answer decide.
Pull the slider to send more visitors at a funnel. The answer starts at no verdict yet, then turns into a verdict once the data has actually decided. This is the engine your dashboard runs on, not a picture of it.

Reading
Nothing to report. The engine will not call anything under 30 funnel starts, and it has 0.
It refuses to answer under 30 funnel starts, and it only reads high once the 95% range sits inside one band. If a segment beats the bar we name it instead of printing don’t build.
Where it works
One working audience can save the whole idea.
Every source, country, creative and audience is scored on its own, so an idea that only works in one place gets found instead of buried.

Read it in one line: the ads and the funnel are fine, the paywall is the leak. Fix the price or the promise before you touch the creative.

Objections
The four questions everyone asks first.
Isn't a paywall for an app that doesn't exist dishonest?
It would be if anyone were charged. Nobody is, and no card is ever collected. The checkout step asks for a name and an email so you can tell them when it ships, and it says on the screen that they are pre-registering for an app that is still being built. What you keep is their decision at your price, and that is the whole point.
How much ad spend does a verdict take?
A first verdict unlocks at 30 funnel starts, usually around 100 visitors or $50 to $100 of traffic. High statistical confidence costs more than that. The dashboard tells you roughly how much more, instead of letting you assume you’re done.
Do you launch the ads for me?
No, and we won’t pretend otherwise. You get the creative, the copy and a tracked link per angle, then launch in whichever ad manager you already use. The upside: those links work on TikTok, X, YouTube, Reddit, newsletters and podcast reads exactly as well as they work on Meta.
What if the verdict says don't build?
Then it cost you a weekend and a hundred dollars instead of four months. You keep the licence, the tokens you haven’t spent, and everything the run taught you about the angle. The next idea starts on Monday.
Four months of building, or one week of finding out.
