Product-led app studio · iPhone, Mac & web

Build what fits. Grow it with care.

We work out what's worth building, then design it, build it and keep it growing.

  • Product judgment first
  • Personal by design
  • AI-forward, built to last

where we fit

Between a weekend build and a big agency.

Anyone can generate an app now, and we build with AI too. What AI doesn't give you is the hard part: knowing who it's for and what to build first, making it personal enough that people come back, building on a foundation that lasts, and staying after launch. We bring how big product teams work, at a size and price that fits.

Vibe-coded

Fast and nearly free

  • Something working in a weekend

Corey Wall

who's behind it

Hi, I'm Corey.

A product leader who designs and builds apps end to end. You work directly with the people building it, from the first sketch to the App Store.

  • Product first. I work out what's worth building, and what to leave out, before anyone designs or codes it.
  • Personal by design. I've spent years building personalization platforms, so the apps I build remember people and give them a reason to come back.
  • AI-forward, not vibe-coded. I build with AI, on the engineering that makes an app hold up. Whether AI goes inside your app is a separate call: it has to earn its place.

Everything an app needs to grow.

Every project starts by evaluating the opportunity and exploring the concept. Add what your app needs from there, each at a price you know up front. Typically, idea to App Store in less than a month, and faster when we're improving an app you already have.

designed for the App Store

Your storefront, designed.

Most people decide whether to download from the screenshots alone. Every build includes a set like these: a story told in five or six frames, written and designed for your app.

  • Shoes on, no nagging: kids see the next step of a mission and check it off themselves
  • Tiny missions, big family wins: pick a mission on the Today screen and hold to start
  • Every effort, noticed: the celebration praises the effort, not just the coins
  • Their coins, your store: rewards like screen time, movie night and a trip to the park
  • Watch the effort add up: levels, streaks and trophies for every kid
  • Make Rally yours: what Rally Plus adds, from routines that run themselves to your own presets
Rally: Family Missions · the App Store set
  • Settle the score: a tentacled boss snaps "Now I'm hangry" mid-fight, because bosses remember every fight
  • One thumb, zero mercy: a 20x combo as you drag to fly, hold to fire and lift to slow time
  • Crown all six sectors: the campaign map, 30 missions and a secret past the Warlord
  • Go flawless: five medals a level on every difficulty, all earned on a perfect clear
  • Fly a ship you earned: the hangar of hulls and engine glows unlocked by mastering sectors
  • Bring on wave 15: Endless mode, with a boss every ten waves
