Custom apps for businesses that outgrew the spreadsheet
Most companies do not need an app. They need one process to stop leaking money — dispatch, billing, intake, inventory. We scope that process first, put a number on it, and only then write code.
- Fixed quote before we build
- iOS, Android and web
- English and Spanish

Three ways to start, depending on how much you already know
Every engagement ends with something you own: a document, a working build, or a product in the stores. These ranges match the numbers we publish in our cost guides — your exact figure comes from your scope, not from a template.
Discovery sprint
For when you know the problem but not the shape of the solution. Two to three weeks, fixed price.
- Process mapped with the people who do it
- User flows and screen inventory
- Clickable prototype you can test
- Technical approach and integrations
- A fixed build quote, itemised
- Yours to take elsewhere if you prefer
MVP build
One platform, the core flows that create value, launched and in real hands. Typically eight to sixteen weeks.
- iOS or Android, or a web app
- Authentication, roles and permissions
- The two or three flows that matter
- Admin panel for your team
- Store submission handled
- 30 days of post-launch support
Full product
Both platforms, real integrations, and an operation that depends on it working every day.
- iOS and Android
- Custom backend and API
- Integrations: CRM, billing, inventory, ERP
- Offline handling and sync
- Reporting and dashboards
- Load testing before launch
What every build includes
A quote before a line of code
We do not start development on an estimate. Discovery produces a fixed number, and if the scope changes we tell you what it costs before we touch it.
You own everything
Source code, repositories, store accounts and documentation are yours from day one. No hostage situations, no licence you have to keep paying us for.
Built to be handed over
Typed code, versioned migrations and written documentation, so another developer can pick it up. We build for the day you do not need us.
Tested where it hurts
The flows that carry money or data get automated tests. Our Halo platform ships with over 1,500 of them — the same standard applies to your build.
Apps we have built
Also in production: Arreconsa, a three-app platform that turns when an aircraft structure enters and leaves the hangar into a fair billing total, and Halo, our own contact centre platform running real operations every day.
When you should not build an app
If the process is not written down yet, if fewer than a handful of people will use it daily, or if an existing tool already covers most of it — an app is the expensive answer. We will tell you that on the call, before you spend anything. A discovery sprint that ends in do not build this has done its job.
How a build runs
Scope
We sit with the people who do the work today, map what actually happens, and find where the money leaks.
Prototype
Screens you can click before anything is built. Cheaper to change a prototype than a database.
Build
Two-week cycles with something working at the end of each one. You see progress, not status reports.
Launch and hand over
Store submission, your team trained, documentation delivered, and 30 days of support while real users arrive.
Frequently asked questions
Why does app development cost this much?
Because most of the cost is not the screens. It is authentication, permissions, data modelling, integrations with systems you already run, store review, and the testing that keeps all of it standing. A cheap quote usually means one of those was left out, and you find out which one after launch.
Can we start smaller than $18,000?
Yes — start with the discovery sprint at $2,000. You get the flows, a clickable prototype and a fixed quote. Some clients take that and decide a no-code tool covers them for now. That is a good outcome.
Do projects in El Salvador cost the same as in Houston?
Ranges for Salvadoran projects usually start lower, because scope and integration requirements tend to be smaller. The work, the standards and the team are the same. Tell us where you are and we will quote your scope, not a region.
What happens after launch?
Apps need maintenance the same way stores do: OS updates, store policy changes, dependency security. Ongoing plans start from $750 a month depending on how critical the app is to your operation.
Can you take over an app someone else built?
Often, yes. We start with a code and infrastructure audit and tell you honestly whether it is worth continuing or rebuilding. Sometimes the honest answer is rebuild, and we say so with the numbers behind it.
iOS first, Android first, or both?
It depends on who your users are and what you are testing. We wrote a full guide on that decision, and we will walk you through it on the call rather than defaulting to both platforms and doubling your budget.
