App & web app studio · Now taking on trouble
*the good kind. Little Menace Studios designs and builds mobile apps and web apps that people can't leave alone. From first sketch to App Store, one tight crew, zero boring software.

01Selected work
Everything we've been caught building. Fintech, social and marketplaces. Designed, built and shipped end to end.
a.k.a. The Vault Job
A full-stack personal wealth platform for tracking net worth across bank accounts, investments, real estate, and collectibles in one place. Live account aggregation through Plaid, subscription billing, and one-click personal financial statement exports.
Charges
a.k.a. The Party Crasher
A shared disposable camera for events. Guests scan a QR to join, shoot a limited roll, and nobody sees a single photo until the host reveals them all together. Seven live party games, in-app purchases, an App Clip for no-install joining, and a web gallery.
Charges
a.k.a. The Fence
A local marketplace built for fast, modern browsing: stronger trust signals, a quicker offer flow, and a dedicated home for yard sales, estate sales, and weekend pop-ups. App-like on the web.
Charges
a.k.a. The Social Club
A social discovery app for finding like-minded friends nearby through shared interests, compatibility, location-aware matching, messaging, and event planning.

02Services
Pick one, pick several. We're a small crew that covers the whole job, from the first sketch to the last App Store screenshot.
iOS and Android apps in React Native and Expo. App Store launches, in-app purchases, App Clips, push notifications, the works.
Next.js products with real complexity underneath: dashboards, marketplaces, SaaS and fintech with live data that stays fast.
Flows, UI systems and clickable prototypes, designed by the same people who'll actually build them. Nothing lost in handoff.
Supabase, Postgres, NestJS, Plaid, payments and subscriptions. The unglamorous stuff that makes the magic trick work.
Got an idea and a deadline? We'll get a real, shippable first version into real users' hands. No throwaway prototype.
Inherited a tangled app? We'll untangle it, speed it up, sand down the UI and get it shipping again.
03How we work
Every good job has a plan. Here's how an idea goes from “what if…” to live in people's pockets.
Week 1
We dig into the idea, the users and the goal. What's the loot, who's guarding it, what does winning look like? You leave with a plan, not a guess.
Weeks 2–3
Flows, wireframes and a UI with actual personality. You click through a real prototype before a single line of production code.
The sprint
Short build cycles with a live preview link from day one. You see progress every week. No black boxes, no surprise invoices.
Launch & beyond
App Store submission, launch, analytics and after-care. We don't vanish when the sirens start. We stick around to make v2 even better.
04The studio
Most software is polite, beige and instantly forgettable. We'd rather build things with a little attitude: apps that feel alive, interfaces that make people grin, and products that quietly handle serious complexity underneath.
Little Menace is small on purpose. You work directly with the people designing and writing the code, not an account manager relaying messages. That means faster decisions, fewer meetings and more shipped software.
