The problem

"I spent 4 months building an app nobody wanted."

Every indie developer has this story. You fall in love with an idea, disappear into Xcode for a season, launch — and hear crickets. The market feedback you needed on day one arrived after month four.

  • Validate the idea, not the code. Test demand with a real funnel before writing a line of Swift or Kotlin.
  • Measure money, not opinions. Surveys lie, friends are polite — visitors reaching for their card don't.
  • Decide with data. A statistical verdict against real web2app benchmarks, not a gut feeling.
How it works

From idea to verdict in three steps

The whole methodology is built in. You bring the idea and a small ad budget — Prelauncher does the rest.

1

Check the idea

Describe your app in a sentence. The AI scores it through a paid-acquisition lens — pain severity, market size, willingness to pay, ad reachability — and suggests sharper directions before you spend a dollar.

2

Launch your test kit

One click generates your complete kit: a polished funnel (landing → walkthrough → pre-registration → paywall), multiple ad angles with scroll-stopping creatives, and tracked links. A step-by-step checklist gets your Meta campaign live in minutes.

3

Read the verdict

Real visitors hit your funnel and we measure everything — clicks, engagement, signups, and checkout attempts. The verdict engine benchmarks you against web2app conversion standards and tells you straight: build it or don't.

The differentiator

Emails are cheap. Reaching for checkout is commitment.

Waitlist tools measure curiosity. Prelauncher measures buyer intent — visitors see your real pricing and decide whether to commit to buy, exactly like the app already exists.

No card is ever collected and nobody is charged. The signal is the decision — visitors who hit checkout and move to confirm are telling you they were ready to pay. They're told the app is coming and they'll be notified at launch; meanwhile you've learned the only thing that matters: would they buy?

FAQ

Questions, answered straight

No fine print surprises.

How can I validate an app idea before the app exists?
Prelauncher generates a real product funnel for your idea — landing page, walkthrough, pre-registration, and a paywall — exactly like the app already shipped. You run a small ad campaign (around $50 of Meta ads) at it, and we measure what cold visitors actually do: who clicks, who engages, who signs up, and who tries to buy. That behaviour is the validation — no surveys, no friends saying "cool idea".
What is the buyer-intent paywall, and is it ethical?
Email signups are cheap; reaching for checkout is commitment. The paywall presents your real pricing, and visitors who commit to buy — moving through checkout to confirm — are the strongest buy-signal there is. No card is ever collected and nobody is charged: visitors are told the app is coming and they'll be notified at launch. When your idea works and you flip to selling for real (Grow plan), the same funnel takes real payments.
What do I need to run a test?
An idea, a Meta (Facebook/Instagram) ads account, and a small budget — most tests get a readable signal from $50–150 of spend over 3–7 days. Prelauncher generates the funnel, the ad images and copy, and the tracked links; you paste them into Ads Manager following the step-by-step checklist. No code, no design skills.
How does the verdict work?
We benchmark your funnel against real web2app industry conversion rates (2–5% visitor→checkout). The verdict engine computes statistical confidence intervals, sweeps every traffic segment (ad, source, country, device), and tells you plainly: BUILD IT, PROMISING — KEEP TESTING, or DON'T BUILD. An idea that converts for one reachable audience is a buildable idea — so we never say "don't build" while any segment is working.
Is it really free to start?
Yes. Create a free account — no card required — and validate your first idea: one project, the AI idea check, a hosted landing page with email / waitlist capture, and 1 AI ad generation to get you going. The free test measures interest — who wants it. To find out whether they'll actually pay (the buyer-intent paywall and market-research quiz), and to test more ideas at once, upgrade to Pro for $149/year.
What's the difference between the Free and Pro tests?
The Free test measures INTEREST: it runs ads to a landing page and captures emails, so you learn who wants your idea and build a launch waitlist. The Pro test measures real DEMAND: it adds a buyer-intent paywall that shows your real price and records whether visitors actually reach for checkout (no card collected, nobody charged), plus market-research quiz steps that reveal which price, audience and message convert. An email signup is cheap — reaching for checkout is commitment, which is why Pro gives you the real build / don't-build verdict.
What counts as an "ad asset"?
Every AI-generated ad image — the scroll-stopping creatives Prelauncher produces for each ad angle. Free accounts get 1 generation to start. The Pro plan includes 50 generated assets per month, which is enough to test multiple ideas with several creative rounds each — and that quota resets on the 1st.
Can I actually sell my app through Prelauncher?
That's the Grow plan (coming soon): connect your own Stripe account, flip the funnel from validation to a real checkout, and use the entitlement API so your iOS/Android app can verify who purchased. Everything you validated — funnel, ads, trained pixels — carries straight over to selling.
Do I need to know how to code or run ads?
No. The AI builds the funnel and the ad creatives; the Validate checklist walks you through launching step by step, including exactly how to set up the Meta campaign. If you can paste a link, you can run a test.
Which app platforms does it support?
iOS, Android, or both. The funnel detects each visitor's device and the dashboard breaks results down by platform — handy when deciding which store to ship to first.
Can I cancel anytime?
Yes — one click in Billing, no emails to send, no retention dance. Pro starts with a 14-day free trial, so cancel before it ends and you're never charged. After that you keep access until the end of the period you've paid for, then drop back to the free plan with your data intact, so you can pick up where you left off.
