Build a Simple App With Claude and Grok, No Coding (Module 5, Lesson 4)

Module 5 · Lesson 4 of 5 · About 20 minutes, plus building time

In Module 4 you built a star chart for your own kids. Now you’ll build a small app other moms would pay for, like a meal planner that makes the grocery list, a homeschool scheduler or a family budget tracker.

Keep it small

Your first app should do one job really well. Not “a family organizer.” Instead: “a 5-day meal planner that makes the grocery list for you.” Small apps get finished. Big ones don’t.

Step 1: plan it

I'm building a simple [app idea] for [buyer]. Look at similar apps and tools people use now. What features do users love, what do they complain about, and what's the one feature that would make a simple version worth paying for? Link your sources.

Help me write a one-page plan for a simple app: [idea] for [buyer]. Based on this research [paste Grok's answer], list: the one main job it does, up to 5 features for version one, what the screens look like, and what's NOT included yet. Keep it simple enough to build in one chat.

Step 2: build it with Claude

Build version one of this app from my plan: [paste the plan]. Use my style card: [paste]. It must work on a phone and a computer, run entirely in the web browser as a single file with no sign-in and no outside services, and save the person's information on their own device so it's still there next time. Show it to me so I can test it.

Then test and fix, one thing at a time, exactly like the star chart in Module 4. Expect several rounds. That’s normal, not failure.

Step 3: make it sturdy

Act like a tired mom using this app for the first time on her phone at 9pm. List every place she might get confused or something might break: empty boxes, wrong buttons, very long text, refreshing the page. Then fix the top problems and add a short help screen.

Step 4: turn it into something you can sell

The simplest way for a beginner: deliver the app as one file the buyer downloads and opens in their web browser, like a PDF but clickable.

1. Download the finished app from Claude as an HTML file.
2. Open it on your own phone and computer to make sure it works without the internet.
3. Write a one-page “How to open your app” PDF: download the file, open it in Chrome or Safari, add it to your home screen if they like.
4. Sell the file and the PDF together, the same way you’d sell a printable (Module 6).

Sharing a link to something in your Claude account is great for family, but it isn’t a way to charge people. The downloadable file is what you sell.
