Got an idea for an app?
I'll build it for you —
in a day, for $500.

You describe what you want in your own words. A day later, your app is live on the internet — working, looking good, and ready for people to actually use it. You don't need to know anything technical.

If you can describe it, I can build it.

What you get

What's included.

A real website, live on the internet

Not a picture. Not a plan. A real website at a real web address that anyone, anywhere, can open on their phone or computer.

A “sign up” button that actually works

People can create accounts and log in — the way they do on any other website. They can sign in with an email and password, or with Google.

It remembers everything

Users, their accounts, whatever your app keeps track of. Nothing gets lost when someone closes the browser or comes back tomorrow.

Nothing technical for you to set up

No accounts to create. No servers. No buttons to click. You don’t touch anything technical, ever. I handle all of it and send you a link when it’s done.

You own it forever

If you ever want to hand it to another developer, sell your idea, or just walk away — it’s yours. No one is holding it hostage.

Optional add-on

Need to take money?

Take payments through Stripe — $150

Your app can charge customers, sell subscriptions, or take one-time payments. You’d create a Stripe account (it’s free, takes 5 minutes) and I’ll wire it up so the money lands in your bank account.

Not a fit

This isn't for you if…

  • ×You want a phone app you download from the App Store (I build websites that work great on phones — but not downloadable apps)
  • ×You want several big features all at once — I build one simple, focused thing at a time
  • ×You want your app to connect to a lot of other outside systems
Why I started doing this

I kept meeting people with great ideas who'd paid someone $15,000 and waited three months, and still had nothing real to show for it.

That shouldn't be how it works. If you have an idea for an app or a website, you should be able to see it, click around on it, and share it with your family this week. Not three months from now. Not for the price of a used car.

You tell me what you want in your own words. I use modern tools to build it, get it online, and send you a short video showing how it works. If what I built isn't what you asked for, I fix it on me. If it is, you're live by the end of the week.

How it works

From your idea to a real website, start to finish.

  1. 01

    Tell me your idea

    5 minutes

    Fill out the form below. Describe the app or website you want in your own words — a few sentences is plenty. Talk about what it does and who would use it.

  2. 02

    I get back to you

    within a day

    I read what you wrote and email you back. Either we’re good to go, or I ask a few questions to make sure I got it right.

  3. 03

    Pay half up front

    $250

    Once we agree on what you want, you pay a $250 deposit through a secure link. I block off the time and start building right away.

  4. 04

    I build it

    about a day

    I build the whole thing, get it online, and make sure it works. No meetings. No status check-ins. Just heads-down building.

  5. 05

    Show and tell

    when it’s done

    I send you a short video walking you through what I built, plus the live web address where it’s running. You can click around, test it, share it with friends.

  6. 06

    Pay the rest

    $250

    If it’s what we agreed on, you pay the remaining $250. If something’s off, I fix it before you pay. That’s it — you’re live.

Everything happens over email and a quick video walkthrough. No scheduled calls unless you want one.

What it costs

$500. Done.

$250 to get started. $250 when it's live.

One flat price. No hourly fees. No hidden charges. No monthly bill.

Need to take payments on your site? Add that on for +$150.

I host your website free for the first 30 days. After that, I can hand it off to you, or keep running it for a small monthly fee — your call.

Common questions

Questions people ask.

No. That’s the whole point. You describe what you want in plain English — like you’re telling a friend about your idea. I handle every piece of the technical stuff. You never touch a terminal, never write code, never set up an account somewhere you don’t recognize. At the end, I send you a website address, and your idea is live on the internet.

Before you pay the second half, I send you a video walkthrough of what I built. If it’s not what we agreed on, I fix it — that’s on me. If it turns out we had totally different ideas of what you wanted (this is rare, because we talk through it first), I give you your deposit back.

You can try, and some people do. But there’s a long way between “the AI gave me some code” and “my website is actually live on the internet and my customers can use it.” Creating hosting accounts, paying for servers, fixing things when they break, making it look right on phones — that’s where most people get stuck and give up. I do all of that for you.

Once we’ve agreed on what you want and you’ve paid the deposit, I block off a day and build your app end to end. Usually this takes 12 to 20 hours of focused work. You don’t have to be available during that time — go live your life, I’ll email you when it’s ready.

I’ll tell you. If what you’re describing needs more than one core thing (for example, it’s really three apps in one), I’ll either help you pick the most important part to build first, or quote you a higher price up front. Either way, no surprises.

Through Stripe — the same service Airbnb and Instacart use to take payments. It works with any credit or debit card. Half when you decide to go ahead ($250), half when the app is live ($250).

Your app lives on my server for the first 30 days, so you can use it and share it with people right away at no extra cost. After that, we have two options: I can hand everything over to you (set up your own account, free one-time handoff, no ongoing relationship), or I can keep running it for you for a small monthly fee. It’s your choice.

Totally fine. When you fill out the form, check the “host on my own accounts” box and I’ll set everything up in your name instead of mine. If you’re not sure what that means, leave it unchecked — I’ll take care of it.

No — I build websites. Your website will work great on a phone (it adjusts to any screen size), but it won’t be something people download from the App Store. If you need a real iPhone or Android app, I’m not your person.

I’ve built a lot of these, I use modern tools that do the tedious work for me, and I’ve gotten it down to a focused process. The whole thing is the same tools and same approach every time — which is what lets me charge $500 instead of $15,000 and still do good work.

Yes — check out Convened (getconvened.com) and InspirationGPT (inspo-app.vercel.app) above. Both were built in a single day. Click around, sign up, try them out. That’s what your app will feel like.
