Everything your clients need, in their pocket.

Guests find their way around town without texting you. Homeowners see their restoration week by week. Clients approve, sign and book without a phone call. We design and build apps that answer the questions your clients would otherwise bring to you, so they feel looked after and you get your time back.

i. Apps for your business

What we could build for you.

Six examples, each built around what one kind of business’s clients keep asking for. Every one carries your brand and your voice, and can work alongside the AI agents that answer and book for you.

ii. Our apps

Real apps built by Bay House Digital.

Three apps we designed and built, for a design studio, a historic house and anyone who loves dogs. Try each one here: it is the same app that runs on the phone.

Carly Richards Interiors app: the client's project home, with the drawing room photograph, this week's update from Carly and the next site visit

The real app, with a sample project.

Client app · iPhone

Carly Richards Interiors

A private app for the clients of an interior design studio. Clients follow their house room by room: they approve selections, sign change orders, see invoices, book site visits, track deliveries and message Carly, all in one place instead of a long email thread.

Guest guide · iPhone

The Strohm House

A guide to a house built in 1870 in Annapolis, Maryland, and to the town around it. Guests learn the story of Matthew Strohm, the Naval Academy's boxing master, see each room before and after its restoration, and walk three tours of the city: historic Annapolis by day, our favourite places to eat and drink, and haunted Annapolis after dark.

Belly Rubs! game board: puppies on a tiled board, each waiting to slide back to its mother

The real game, running in your browser.

Puzzle game · iPhone and Android

Belly Rubs!

A sliding puzzle about puppies. The pups block each other's way, and you rub a pup's belly to slide it to the mom that looks like it, before the clock runs out. Each litter is harder than the last, and the whole family gets to the adoption fair in the end.

iii. How an app gets made

From the first sketch to the App Store.

We handle the design, the build and the store listings. You approve each stage before the next begins.

PlanWhat it must do
Who will use it, the three or four jobs it does for them, and whether it should be on iPhone, Android or both.
DesignScreens you can try
Working screens on your own phone before a line of the final app is built, in your brand and your photographs.
BuildiPhone, Android or both
One app built for each store, with a privacy page and a support page written to the stores' rules.
PublishListed and looked after
We prepare the listing and screenshots, answer the stores' review questions, and keep the app up to date.

Pricing

Three ways to start.

The same three packages for any kind of app: a guide for guests, a portal for clients or a companion for readers and listeners. Every app ends in a fixed-price proposal.
