App builds · for owners and teams

Own the tool.
Don’t rent it.

I build the app your team keeps working around: on your accounts, for a fixed price agreed before I start, and checked on a real phone before it goes live.

Book a 30-minute scoping callOr build it yourself: the $750 pilot

What you get · agreed before any work

  • Yours from the start. The app, its name, its accounts and the code written for it live in your GitHub and your Vercel. If we part ways, you keep them.
  • A written scope and a fixed price before the build starts.
  • A preview link every week, so you see it take shape and steer it.
  • Checked work: automatic tests, screenshots on phones and computers, and a privacy and security check against a written checklist before launch.
  • 30 days of fixes after launch: if something I built doesn't work as agreed, I fix it free.

How it works · four steps

  1. A 30-minute call. No pitch. If an app isn't the answer, I'll say so.
  2. A written scope and a fixed price. Business builds start with a paid scoping step.
  3. The build, with a preview link every week.
  4. Launch, then 30 days of fixes.

Built this way · one app, live today

Habit of Grace, a private journal app: built with this method, checked by hundreds of automated tests, and live at habitofgrace.com (opens in a new tab).

Rather build it yourself? · The Three-Call Pilot

Your own app, with me beside you.

Your own app on your phone in about three weeks: built by you, with Claude, and with me beside you for three 30-minute calls.

  • The guide: the method I used to build Habit of Grace, with templates to copy.
  • The starter kit: the files I begin every project with, ready on your first day.
  • Three calls: your idea and setup; your app on your phone, and what to cut; going live.

A good fit for one job you can say in a sentence, with your data on your own phone. Logins or shared data need a build; card payments and App Store apps aren’t offered.

$750Plus Claude Pro at $20 a month. Hosting is free for a personal app. Switch to a build within 30 days of starting and your $750 counts toward it.

What it costs

Build it with me, or have it built.

For your team, a business build. For a tool only you use, the pilot or a small build.

The Three-Call Pilot

$750

You build it with Claude: the guide, the starter kit and three 30-minute calls. About three weeks. Plus Claude Pro, $20 a month.

A small build

$2,500–$5,000

One or two screens, with your data on your own phone. Two to three weeks.

A medium build

$8,000–$15,000

Habit of Grace-sized: several screens, works offline, backups, and a website with a small database. No logins. Four to eight weeks.

A business build

$15,000–$30,000

A tool for your team: logins, shared data, and roles for staff and admins. Six to ten weeks, after a two-week scoping step.

A business build starts with a two-week scoping step, $2,500: a working prototype of the most important screen and a written scope, credited to the build if you go ahead. Every price is fixed in writing before the build starts. You pay half when you approve the scope, and half at launch or 14 days after handover, whichever comes first. Builds run on your own hosting, paid by you directly: Vercel Pro, about $20–$40 a month, and a domain, about $15 a year. Campaigns and political committees pay the same published prices and terms as every client.

Not sure which? · Up to three questions

The pilot, or a build?

Question 1 of 3

Who will use it?

Nothing you pick is stored or sent.

Straight answers

Asked before every build.

You do, from the first day: the app, its name, its accounts and the code written for it, in your GitHub and your Vercel. Code I wrote before your job stays mine, and you get a permanent, free right to use and change it. If we part ways, you keep everything built so far, plus two plain documents that let anyone carry on.

Book

Thirty minutes.
No pitch.

Tell me what the app is for and who will use it. If an app isn’t the answer, I’ll say so on the call.
