Pilates studio · website and app

Strong, calm, and booked in two taps.

One build. On a laptop it's the studio's website. On a phone it's the booking app, right on the home screen. No App Store needed.

One build, every screen

Watch the website become the app.

  1. On a laptop, it's the full website.
  2. On a tablet, the same build reflows.
  3. On a phone, it turns into the app, tabs and all.
  4. On the home screen, it opens like any app. No App Store.

Try it yourself

This is the app. Book a class.

It works for real in this page. Pick a day, book, check your classes, show your card. Then turn off the internet.

Same build as the websiteOne codebase, so a change to a class shows on the site and in the app at once.

The big question

Web app, or App Store app?

"App" can mean two very different jobs. Flip between them. This is the first thing we'd settle.

Extra costs
Fits a $2,000 budget

Don't take my word for it

Put this page on your home screen.

This concept is a real web app. Add it and it opens full screen with its own icon, like anything from the App Store.

How we'd match your example

Four steps, no surprises.

1

Send the example

The site or app you have in mind, plus anything you like or don't.

2

Screen by screen, in a day

I come back with every screen, what it does, and a firm price.

3

One build

The website and the app are built together, so they never drift apart.

4

Launch and install

Live on your domain. Your customers add it to their phones in two taps.

Your turn

Send me your example. I'll match it.

This page is a sample I made for your post. Calla is not a real studio.
