What we do
App for a Day creates a simple, friendly app for any event, big or small, lasting one day or many days. Whatever information you wish to share with your participants and attendees, we bring it together in one easily accessible place - no need for confusing group chats or email chains.
Built just for your event
Not a generic template. We custom build your app around the specific event you are organising, whatever that looks like.
Built around how you work
Keep organising your event your way, and we'll build the app to match what you produce. It's that simple.
Built for attendees, not app stores
No downloads, no accounts, no passwords to forget. Just a simple link with everything your attendees need.
Sound familiar?

I'm a digital problem-solver, I take information that's scattered and hard to find and turn it into something simple that works.
After ten years as an architect, I moved into construction technology as a Digital Information Manager, leading the shift from paper drawings to connected, data-rich digital models for one of Ireland's leading contractors and then architectural practices.
I'm also a busy parent of three, juggling many community activities every week. In June 2026, keeping track of my kids' club mini All-Irelands (four five-day blitzes, different times, different pitches, different age groups) became a real headache. So I did what I'd spent years doing in construction: turned scattered information into one connected system. I built an app for the final week of the blitz, and it took off, with over 800 active users during the week. App for a Day was born.
Since then, I've built apps for more blitzes, sports days, and feiseanna, with the same positive result each time. I'm passionate about making busy people's lives that little bit easier, one event at a time.
