CORE -
one app for a
whole world.

CORE sells a whole lifestyle: social wellness clubs, hospitality, residences, dining, adventures, apparel, and private yachts on the Red Sea. This was a proposal from the studio I work with to CORE, and I want to be clear up front, it was a pitch, not a shipped product. I designed the whole thing solo in three weeks, one mobile app meant to hold CORE's entire world, so a member could reserve a gym class, book a table, plan an adventure, or charter a yacht from the same place.

The hardest problem was exactly that range. Making one app hold services that have nothing operationally in common, from a fifteen minute gym slot to a multi day yacht charter, without it turning into seven unrelated mini apps bolted together.

CORE positions itself at the very top of the market: social wellness clubs in Riyadh, Jeddah, and Egypt, CORE Beach and private yacht escapes on the Red Sea, with hotels and retreats on the way. The through line is curated, premium, wellness first.

That premise set the bar for the app. If CORE claims to be the most exclusive lifestyle brand in the market, the app cannot look like a generic booking tool. The design had to earn the positioning, not just support it.

CORE offers a lot, and none of it lived in one place. A member wanting to use the gym, reserve a table, rent a yacht, or book an adventure had no single way to see what was available and reserve it. The brief was blunt: one app where you can check and reserve every CORE amenity.

The design problem underneath it was that those services do not book the same way. A gym class is a slot. A yacht is a charter. An adventure is an itinerary. A residence is a stay. The question I set out to answer was how to make all of those feel like one coherent act of reserving, under one home, one identity, and one language, instead of four different apps wearing the same logo.

This was a proposal, so here is how it was actually made. Three weeks, solo. What I had was CORE's positioning and a brief that came down to “put all of it in one app.” So the work was not discovery, it was a design argument.

I worked from the brand outward, decided how the whole thing should hang together, then built the case screen by screen. The bar was single and strict: it had to feel as premium as CORE claims to be, across every one of those services, or the pitch says nothing.

Entry and personalization

• Sign up and sign in. Fast, premium, the first impression.
• Onboarding. Sets up who you are and what you are here for.
• Interests across every service. Wellness, dining, adventures, yachts, apparel, you pick.
• Plan choice. Membership tiers, chosen up front.
• System suggested program. Interests turn into a proposed program, not a blank catalog.

Home and assistant

• Home screen. One place that pulls the whole world together.
• AI assistant. A shortcut through everything CORE offers.

Reserve and book

• Reservations for every amenity. Gym to residence to yacht, one act of booking.
• Bookings. Manage everything you have reserved.
• Drag and drop calendar. Arrange your schedule directly, not from a list.
• 3D amenity tours. See the space, then book it.

Health

• Goal creation. Set gym and health goals in the app.
• Apple Health and Apple Watch. Health data and the watch, integrated.

Pay

• Payment and checkout. One checkout across every service.

Holding all of it together is one reservation model and one design language. That is what lets a gym slot and a yacht charter live in the same app without feeling like two different products.
