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, hosted for you at prelauncher.com/app/{your-app}. 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".
Can I just collect a launch waitlist?
Yes. Every project gets a shareable landing page at prelauncher.com/app/{your-app} that captures email pre-registrations — so you can prelaunch your app, build a launch-day waitlist, and gauge interest before you build. When you want a harder signal than curiosity, turn on the buyer-intent paywall to test real pricing and demand.
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.
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.
How much does it cost?
One payment, forever. Prelauncher is a one-time Lifetime account — currently $149 (founding price, going up to $199). No subscription, no yearly bill. Every Lifetime account includes 50 tokens to generate AI ad creatives, and you can buy more tokens any time. There's a 30-day money-back guarantee — if it's not for you, email us for a full refund.
What are tokens?
Tokens are how you pay for AI ad-image generation — the scroll-stopping creatives Prelauncher produces for each ad angle. Your Lifetime account starts with 50 tokens; generating an ad image costs a handful, and you can top up with a token pack any time. Writing ad copy and angles, hosting your funnel, and the verdict engine are all included — tokens only cover AI image generation.
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.
What if it's not for me?
You're covered by a 30-day money-back guarantee. If Prelauncher isn't a fit, email us within 30 days of your Lifetime purchase and we'll refund you in full — no retention dance.
