Would they buy? Find out before you build

Hey everyone,

Today I’d like to share one of my projects with you: willtheyconvert.com. I actually built it a while ago, but it’s still one of my favorite little tools.

The idea is simple: it helps you test if people would actually pay for your subscription or product. You just generate a “Buy” button, and when someone clicks it and starts entering their details, you can show them a message that the app is still in progress (don’t worry – no card data is collected or saved).

Here’s a quick demo: https://willtheyconvert.com/demos#payment

This way, you don’t need to build a full product, set up Stripe, webhooks, or a whole app that maybe no one would ever use. Instead, you can just launch a landing page and promote it as if the product already exists. You’ll avoid the usual “Looks great!” or “Awesome idea!” comments that sometimes end up meaning… nobody was ever ready to buy. With this tool, you can see if people actually click “buy” in the first place.

You can also collect emails from those who clicked, so once the product is ready, you can reach out directly.

When testing this app myself, I experimented with different payment models:

• First I tried a monthly subscription (no trial). It sold 2–3 copies right after launch, and then nothing.
• Then I switched to a lifetime deal – sales picked up.
• I got greedy and changed it to an annual subscription (with a 3-day trial) – sales dropped again.
• A couple of weeks ago I switched back to lifetime only, removed the trial completely – sales started moving again.

For apps like this, I really think the lifetime model works best, and ironically it seems to convert better.

Hope you found this interesting and as always, keep shipping 🚀🔥
