I build custom web apps that turn the work you do by hand into something that runs itself: booking, quotes and invoices, client portals, dashboards and AI assistants. They run in any browser and install on phones like an app.

## What you get

- **Booking & scheduling**: Online booking with reminders, so the phone stops being your calendar.
- **Quotes, invoices & payments**: Quotes that become invoices, PDF documents and online payments in a few clicks.
- **Client portals**: One private place for your clients’ files, forms, messages and payments.
- **Dashboards & reports**: Your numbers in one live dashboard, with reports that arrive on their own.
- **AI assistants**: Assistants that answer questions from your own documents and handle routine requests.
- **Installable apps**: Progressive web apps that install on phones, send notifications and work offline.

## How it works

1. **Map it**: We walk through how the work gets done today and where the time goes.
2. **Blueprint**: You get the screens, the features and a fixed quote before any code.
3. **Build**: I build it in stages, and you try each one as it’s ready.
4. **Run**: Launch, hosting and support, with improvements as your business changes.

**Who it's for:** Service businesses, Schools, Clinics, Agencies, Contractors, Startups, Nonprofits

## Frequently asked questions

### What kind of apps do you build?

Web apps that run a part of your business: booking, enrollment, quotes and invoices, client portals, dashboards and AI assistants. I also build and run my own apps, like DayQuizz and STL Ruler.

### Do I need an iPhone and Android app?

Usually not. A progressive web app installs from the browser on iPhone and Android, sends notifications and works offline, without app store fees or reviews.

### Can it connect to the tools I already use?

Yes. Apps can connect to payment, email, calendar, accounting and other tools through their APIs.

### How much does it cost?

Every project is quoted after a free call, and the quote is the price: no hidden charges, no surprises.

### Who will I be working with?

Me, Chris Arock, from the first call to every update after launch. dcArock is a one-person studio on purpose: no account managers and no hand-offs.
