Tell us, and we build it as your own app. The same way we make everything here: yours to keep, private by design, no subscription and no account. This is where the endless possibilities begin.
The Big Day Studio makes beautiful, private digital tools. The planners and journals in our shop are the ones we dreamed up. The Studio is the other half: the tool that only you need, built to order, just for you.
You describe what you wish existed. We design and build it as your own app. It lives on your home screen with its own icon, opens full screen, works offline, and keeps everything on your device. One payment. No subscription, no account, no app store.
A real person reads every request, usually the founder. We tell you honestly whether we can build it, what it would do, and what it costs. No obligation, ever.
The tracker you downloaded wants a few pounds a month, forever, for something you use twice a week. The free one pays for itself by selling what you type. Half of them want an account before they will even open, and the rest stop working the day the company behind them does.
It adds up. A handful of forgotten subscriptions quietly leak hundreds of pounds a year, and your information ends up on servers you will never see. You end up renting your own habits back, month after month.
An app you own is the opposite of all that. You pay once. It is yours. It asks for nothing, sends nothing, and still opens in ten years.
A simple, lovely tool that does one thing well, lives on your phone, and belongs to you. A few we would happily make:
Bespoke software normally costs a small fortune. While the studio is young, we are taking a limited number of custom builds at a founding price, far below the usual, in exchange for helping shape what we build next.
Tell us your idea and we send an honest quote. No obligation.
Almost any simple, single-purpose tool: a tracker, a log, a planner, a journal, a checklist. If you can describe what it should do, we can usually build it as your own installable app.
Message the shop with the tool you wish existed and what it should do. A real person replies, usually the founder, and tells you honestly whether we can build it and what it would cost. No obligation.
Custom work is priced per project. While the studio is new we are taking a small number of builds at a founding price, far below typical bespoke software. Message us with your idea for a quote.
You own it. One payment, no subscription, no account. Your data stays on your device, and your build includes a file edition so it is yours forever, whatever happens to the internet.
Message the shop and tell us the tool you wish existed and what it should do. We reply, usually the founder, with an honest yes or no and a price. The first step costs nothing.
