Booking
Booking & scheduling
Online booking with reminders, so the phone stops being your calendar.
Custom web app development:
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.

FAQ
Questions, answered.
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.
