Mobile apps with scope, price and date in writing

I build apps for your customers or your operation, connected to your backend or a new one, and I stay with you until they are published in the stores.

V1 is defined in writing: what goes in, what stays out and what each thing costs before a single line is written.

This is for you if

  • You need an MVP to validate the idea in the market before investing more.

  • You want an app for your customers, with order or appointment tracking.

  • You already have a backend or a system and need a solid app on top.

  • Your current app crashes, is slow or people drop it, and you want to know why.

What goes into V1

  • Written scope

    What V1 does, what is left for later and which decisions stay open, so the price doesn't change halfway.

  • Key screen design

    The main flow and the screens used the most.

  • iOS and Android development

    A single codebase, with adjustments from your feedback on every delivery.

  • Backend integration

    I connect the app to your APIs or build the backend that is missing, with authentication and error handling.

  • Build and publishing

    The build and a guide for the App Store and Google Play, with the accounts under your company's name.

  • Initial support

    Monitoring and fixes after launch, when the real cases show up.

Store accounts, policies and final assets are worked on together with your team.

Three items, always in this order

  • Assessment

    US$590

    fixed price · 5 business days

    Users, features and constraints; the V1 scope and its fixed price. Credited in full if you hire.

  • App V1

    from US$2,790

    fixed price · 6 to 10 weeks

    Key screen design, iOS and Android development, backend integration, store publishing and initial support.

  • Evolution

    per stage

    fixed price for each stage

    New features and maintenance once the app is in use. Each stage is quoted before it starts.

Prices in USD, plus VAT. Store fees and third-party services are paid by your company directly.

From the idea to the store

  1. 01

    Scope

    3 to 7 days

    We define goals, users and product constraints. This is the assessment.

  2. 02

    UX/UI

    1 to 2 weeks

    I design the flow and the key screens of V1.

  3. 03

    Development

    3 to 8 weeks

    Iterative implementation with testing and performance work.

  4. 04

    Launch

    1 to 2 weeks

    Publishing, monitoring and initial fixes.

In writing, before we start

Scope and price in writing, money back if it isn't as agreed

You see the scope and the price in writing before we start. If anything fails within 90 days, I fix it at no cost. If it doesn't end up as we agreed, I return your deposit.

The keys are yours

Store accounts, code and access stay under your company's name. If you switch providers, you leave with everything.

No open-ended hours

Each stage has a written scope, price and date. If something changes, it is agreed before it is done.

What I don't do, and who this isn't for

  • This isn't for you if you want a web page that looks good on a phone: that is a site, not an app.
  • I don't publish with my own developer account: the store accounts belong to your company.
  • I don't start without the V1 scope in writing.

What people ask before an app

Do you build MVPs?

Yes. I define with you a first launchable, measurable version to validate the idea before investing in more features.

Does it include iOS and Android?

Yes, usually with a single cross-platform codebase. The concrete strategy is set in the assessment according to scope and budget.

Does it include a backend?

It can be included or integrated with the one you already have. It is defined in the assessment because it changes scope and price.

How long does an app take?

It depends on the features. A V1 usually takes between 6 and 10 weeks from the signed scope.

Do you publish to the stores?

I walk you through the build and the App Store and Google Play publishing. The developer accounts belong to your company, under your name.

Do you provide support afterward?

Yes. V1 includes initial support; after that, maintenance and new features by stage, at a fixed price.

How much does it cost?

The assessment costs US$590 + VAT and is credited if you hire. An app V1 starts at US$2,790 + VAT at a fixed price; the exact amount comes from the scope agreed in the assessment.

Who owns the code?

You do. The code lives in a repository under your company's name from day one, along with access and documentation. If you ever switch providers, you leave with everything.

How fast do you reply?

I reply within 1 hour during business hours and within 24 hours outside them.

How do I pay?

In stages, at a fixed price agreed in writing before we start. No open-ended hours: if the scope changes, we agree on it before doing it. You can pay by card, bank transfer or OXXO.

Tell me which app you want to launch.

Two lines are enough (who would use it, what it would do and whether you already have a backend) and I'll tell you whether the assessment makes sense and what would go into V1. I reply within 1 hour during business hours and within 24 hours outside them.
