One Thing Well

Your app idea, cut down to the first version you can actually publish.

A free prompt for ChatGPT, Claude or Gemini. 15 minutes, 8 questions, one card: the one thing your app does first, and what waits for updates.

One thing, done well.

Who's your app for?
How many hours a week can you spend on it?
Do you code? (optional)
Have you ever paid for an app builder, a developer or an agency? (optional)

What's inside

Nothing to install. 15 minutes with an AI chat you probably already use.

  1. 1

    The prompt

    Paste it into ChatGPT, Claude or Gemini. It asks you about 8 questions, one at a time, like a good product manager would.

  2. 2

    Your v1 card

    The one thing your app does first, 3 steps, up to 3 screens. Everything else goes on the update list: v1.1, v1.2, v1.3.

  3. 3

    A short PDF guide

    A full example card, why one thing works, how to check your problem is worth it, and what to know before the stores.

A real card from one of my test runs:

One thing well

Tap Dinner

Tap Dinner helps busy parents turn the week's dinners into one grocery list.

Stage 1 · Version 1.0This is your goal

Pick easy family dinners and get one grocery list with nothing missing.

  1. Tap dinners from the built-in list
  2. See one combined grocery list
  3. Check off items while you shop

Later, as updates

  • v1.1Add your own dinners; Mark items you already have
  • v1.2Share the list with your partner; Save family favorites
  • v1.3Paste a recipe link; Sort the list by store aisle

Why one thing?

Most first apps never come out. There's always one more feature to add first. The card fixes that: version 1 does one job, start to finish, and every other idea gets a spot on the update list. You're not dropping ideas. You're scheduling them.

Is this for you?

It's for you if

  • You have an app idea for yourself, something you run, or a client.
  • You have a few hours a week to work on it.
  • You don't code, or you've tried an AI app builder and got stuck.

It's probably not for you if

  • You already build mobile apps for a living. You know most of this.
  • You want a get-rich-quick app empire. I can't promise that, and I won't.

I'm a developer. Is this for me?

Yes, if mobile is new to you. You don't need me to learn the code part. Where I save you weeks is the road to the stores: signing, test builds, iPhone builds without a Mac, Google's 12 testers for 14 days, and review. No, if you already ship mobile apps. You know this stuff.

Hi, I'm Adam

I've been building mobile apps since 2015. Started with iOS and Swift, and I've been all in on Flutter since 2019, building my own apps and working as a senior mobile developer.

I also taught coding for years. Now I build apps with AI agents, and honestly, the hard part isn't the code anymore. It's knowing what to build first, and how to get the app into the stores. This prompt is the first part.

I'm opening my first English course cohort in January 2027. Signing up puts you on the early list. No spam, unsubscribe anytime.
