Web and mobile apps, built to ship and built to hand over

One team for the whole thing. Scoping, interface, API, data model, cloud infrastructure, and the app store release at the end.

Start a scoping conversation
  • iOS, Android, and web from one TypeScript codebase, with native modules where the device demands them
  • CI/CD with automated tests, staged rollout, and one-step rollback before the first production release
  • Infrastructure defined in Terraform, running in your AWS account under your billing
  • App Store and Google Play developer accounts registered to your company, never to ours
  • Handover pack: architecture overview, deploy and rollback runbook, data model walkthrough
  • Fixed-scope pricing for defined builds, monthly engagements for products still finding their shape

What we build

We do custom web and mobile app development end to end, for companies that need a working product and not a prototype. That's the interface people use, the API behind it, the data model underneath, the AWS infrastructure it runs on, the pipeline that puts changes into production, and the App Store and Google Play releases at the end.

Most projects start one of three ways. A founder with an idea and no code. A business running a real operation on spreadsheets, a shared inbox, and a group text, who needs an actual internal application. Or a company with a web product that now needs a mobile app next to it and doesn't want two teams building two disconnected things.

We write TypeScript across the whole stack. React on the web, React Native for iOS and Android, Node services behind them, AWS underneath, Terraform describing all of it. One language everywhere means the same engineers move between layers. Nobody throws work over a wall and waits.

How a build actually runs

Four phases. Scope, skeleton, iterate, release.

Scope is mostly subtraction. We turn what you want into what gets built, and we write down what version one includes and, more usefully, what it leaves out. If a feature survives this phase, somebody can say out loud why it exists. Everything else goes on a list, not into the build.

Then the skeleton. Before any feature work, we build the thinnest version of the entire system that genuinely works. A user signs in. One real record moves through the real API into the real database. The whole thing deploys to a real environment through the real pipeline. Nothing is stubbed. It feels slow, and it's the reason the last month of the project is calm instead of frantic. You want your integration problems showing up in week two, while they're still cheap.

Iteration is weekly. Features land in an environment you can open and click, so progress is something you use and not something you read in a status doc. Priorities can move between weeks. The skeleton is already carrying the weight.

Release is a checklist, not an event. Store submission, production cutover, monitoring wired to an alert destination a human actually reads, and a written runbook for whoever has to operate this thing on a Tuesday.

Mobile apps: the parts that surprise people

The code is rarely the hard part of a mobile app. Distribution is.

App review rejects builds for reasons that have nothing to do with whether your app works. Missing in-app account deletion. Privacy disclosures that don't match what the app actually collects. Sign-in requirements, payment rules, a permission prompt with no stated reason. We design around those rules during the build, so you're not reading store guidelines for the first time the week you planned to launch.

Shipping is also permanent in a way the web isn't. Once a version is installed, some people stay on it for months. So API compatibility becomes a design constraint from the first release. Old clients have to keep working while new ones move forward, which means versioned endpoints, additive schema changes, and a forced-upgrade path you can pull when you truly need it.

Then there's everything nobody scopes. Push notification certificates and the day they quietly expire. Deep links. An internal test track for your own staff. Crash reports that map back to real source instead of minified noise. Offline behavior for the person using your app in a basement, a warehouse, or a moving truck.

We run these submissions on our own products every release cycle. RescueShift is live on iOS, Android, and web, so app review, staged rollouts, and supporting old versions are things we do for ourselves and not only for clients.

The stack we default to, and when we leave it

We default to a boring stack on purpose. TypeScript, React and React Native, a relational database, containers on AWS ECS, infrastructure in Terraform, GitHub Actions for delivery.

Boring means well documented, widely known, and hireable. When you bring engineers in-house later, we want your job posting to describe technology people already use, not a stack we happened to find interesting. It also means the failure modes are known and searchable at two in the morning. That's when you'll need them.

We leave the defaults when the problem asks us to. Native modules when a device capability needs them. A queue when work shouldn't happen inside a request. A separate service when one part of the system scales differently from everything else. A different database when the data genuinely isn't relational. What we won't do is pick a technology because it's new, or add a service because the architecture diagram looked more impressive with it on there.

What ships with the first release, not the third

Infrastructure, deployment, and monitoring are part of the build. They're not a follow-up project we quote you later.

Before your first real release you get a pipeline that runs the test suite and deploys on merge. A rollback that takes one step. All infrastructure in Terraform, so environments are reproducible and not hand-assembled from somebody's memory. A staging environment close enough to production to be worth trusting. Error tracking that wakes up a person. Secrets in a secrets manager and not in a file someone committed two years ago. Database migrations that run automatically and can be reversed.

None of that gets billed separately. A release you can't roll back isn't finished. The most expensive projects we get called into are the ones where somebody saved money by skipping all of it, then spent a year too scared to deploy on a Friday.

What you get at handover

Everything. Repositories, cloud accounts, pipelines, store listings, documentation. Yours, in your name, from the first week.

We build in your AWS account when you have one and set one up in your name when you don't. App Store and Google Play developer accounts get registered to your company on day one. An agency holding your developer account is a hostage situation, and we won't create one. Not even for ourselves.

Handover comes with an architecture overview that explains why the system is shaped the way it is, a runbook covering deploy, rollback, and what to do when a specific thing breaks, a walkthrough of the data model, and an honest list of what we'd build next and what we'd fix first.

You can keep us on for ongoing work, and plenty of clients do. That should be a choice you make. It should never be the price of access to your own product.

How projects are priced and structured

We quote after a scoping conversation, never off a price list. The same feature list can cost wildly different amounts depending on what surrounds it.

The real driver is surface count. Web only, or web plus iOS plus Android. After that it's integrations with systems you don't control, whether design already exists or has to be created, compliance and audit requirements, and whether data has to be migrated out of something that's still running while you migrate it. Feature count matters less than almost everyone expects.

Well-defined work runs fixed scope, fixed price. Work that will change as you learn from real users runs as a monthly engagement with a scope you can steer. We'll tell you which one fits. Usually it's fixed scope for version one, monthly after launch.

The scoping conversation is free, and it isn't a sales call with the proposal already written. If your budget doesn't match the scope, we'll say so and describe what the smaller version looks like.

When we are the wrong choice

Some projects shouldn't come to us. Saying so on the first call saves everybody a month.

If you need six engineers starting Monday, that isn't us. We're small and senior on purpose, and we won't hire strangers to fill a bench for one project.

If you want the cheapest possible build, and you think tests, infrastructure, and documentation are padding, someone will do it for less than we will. You'll pay the difference back inside a year or so. But the first invoice will be smaller, and wanting that is a real thing to want.

If what you need is a marketing site or a content-driven page, hire a designer and use a good CMS. You'll get a better result for a fraction of what custom application work costs.

And if your idea depends on a data source, a license, or a partner you don't have yet, the build isn't the risky part. Go solve that first. We're happy to help you figure out which part is actually the risk.

Common questions

How long does it take to build a custom mobile app?
Surface area drives the timeline more than feature count does. A focused first version with one type of user, one platform, and no messy integrations takes months, not weeks. Add a second platform, an admin interface, payments, or a system you don't control, and it stretches meaningfully. WhyUAscii LLC commits to a date in the written proposal after a scoping conversation, because quoting a timeline before you know what has to be built is just guessing with confidence.
I have an idea but no spec, wireframes, or technical documents. Can you still start?
Yes, and that's the normal starting point. WhyUAscii LLC runs a scoping phase that turns an idea into a written scope: who uses the product, what they're trying to get done, what version one includes, and what it deliberately leaves out. You don't need a technical document to begin. You do need to describe the problem and who has it.
Can one team build both the iOS and Android app, or do we need separate developers?
One team can build both. WhyUAscii LLC builds iOS and Android from a shared React Native codebase in TypeScript and drops to native code only where a specific device capability requires it. Features stay consistent across platforms, and a change ships to both stores from one pull request. Nobody implements it twice.
Who owns the App Store and Google Play developer accounts for our app?
You do. WhyUAscii LLC registers developer accounts in the client company name from the start and never holds a client app under its own account. Same for the AWS account, the domains, the repositories, and the CI/CD pipelines. If an agency holds your store account, you can't leave them without abandoning your app and every review it has earned.
Can you take over an app another agency or developer already started?
Yes, and it starts with an assessment, not a promise. WhyUAscii LLC reads the existing code, deploys it from a clean machine, and checks whether the infrastructure, accounts, and store listings can actually be transferred. You get an honest recommendation: keep going, partially rewrite, or replace. The reasoning is written down so you can argue with it.
Should we build an MVP first or go straight to the full product?
Build the smallest version a real user would pay for or depend on. That's not a demo, which only proves an idea is possible, and it's not a full product, which assumes you already know what people want. WhyUAscii LLC builds first versions on production infrastructure with real deployment and monitoring, so the thing you learn from is also the thing you keep.
Do we have to keep paying you after the app launches?
No. WhyUAscii LLC hands over every repository, cloud account, pipeline, and store listing, along with documentation and a deploy runbook, so an in-house or third-party team can pick it up. Monthly support is available if you want it. It's an option, never a condition of keeping your product running.
Do you handle design, or do we need to hire a designer separately?
WhyUAscii LLC designs the interface as part of the build: screen flows, states, and the component system the app gets assembled from. If you need original brand identity, illustration, or marketing design, that's specialist work. We'll say so and help you scope it out to someone who does it well, because doing it badly in-house helps nobody.
What if our app needs to work without an internet connection?
Offline support is an architecture decision you make at the start. It changes how data sits on the device, how changes get queued and synced, and what happens when two people edit the same record while both are disconnected. WhyUAscii LLC scopes offline behavior explicitly during design, because retrofitting sync into an app built for a live connection usually means rewriting the data layer.
