    Signals you need a web app

    When a normal website is not enough.

    • You need a quote calculator, booking flow, intake form, dashboard, portal, or internal tool.
    • Your team is still using spreadsheets, inboxes, and manual follow-up to run important work.
    • Customers need a simple way to request, check, calculate, upload, book, or submit something.
    • You want a lead tool that turns website visitors into quote requests, calls, bookings, or qualified inquiries.

    Why a web app

    When a website is not enough.

    A website explains what you do. A web app lets someone do something.

    If a visitor needs to check eligibility, calculate a quote, submit details, practice a skill, search a library, generate leads, track progress, or move through a workflow, a custom web app may convert better than another static page.

    Visitors need a tool

    They do not just need information. They need to run a check, get a result, or complete a task.

    The workflow is repeatable

    The same intake, scoring, estimate, training, search, or report happens often enough to turn into software.

    The business needs proof

    Analytics, dashboards, saved results, payments, and user flows make the app measurable.

    What is included

    What a web app build can include.

    Public landing and SEO pages

    Search-friendly pages that explain the tool, audience, use case, and next action.

    Core app workflow

    The main user flow where someone enters information, completes a task, gets a result, or views output.

    User accounts or gated access

    Authentication when the app needs saved data, private history, or paid access.

    Admin dashboard

    A backend view for leads, users, submissions, reports, payments, or content.

    AI features

    Drafting, scoring, summarizing, generating, routing, or recommendations where useful.

    Payments

    Stripe checkout, paid tiers, credits, one-time purchases, or subscriptions when the scope supports it.

    Analytics

    PostHog or event tracking for activation, conversion, retention, and key actions.

    Handoff docs

    Loom, docs, prompt logic, app map, ownership notes, and care plan where needed.

    Process

    How Evoworks builds a web app.

    1. Step 1
      Define the app job

      Who uses it, what they do, what result they need, and what the business gets from it.

    2. Step 2
      Scope the first version

      Pick the smallest useful flow before adding extra screens or features.

    3. Step 3
      Design the user path

      Map landing page, input, action, result, follow-up, and owner / admin view.

    4. Step 4
      Build and connect

      Create the app, connect the needed tools, add data storage, auth, analytics, payments, or AI where scoped.

    5. Step 5
      Test with real examples

      Check mobile, edge cases, forms, emails, events, SEO basics, and user flow.

    6. Step 6
      Launch and improve

      Ship the first version, watch usage, then expand only where the app proves useful.

    The first version should do one valuable thing clearly.

    Pricing

    App builds are scoped before they are priced.

    Custom web apps are application-only because price depends on user flows, data, accounts, payments, AI features, admin tools, analytics, and care needs.

    Starter Web App
    from $3,000 setup

    One core flow, basic auth or no auth, simple admin view, light analytics. Best for a focused first version.

    Standard Web App
    from $5,000 setup

    Multiple flows, accounts, dashboard, payments or AI features, SEO pages, analytics, and care handoff.

    Advanced Web App or SaaS MVP
    Custom quote

    Multi-role app, deeper data, AI workflows, multi-tier payments, advanced admin, and ongoing care plan.

    Optional care: from $199 per month

    Client pays for required hosting, database, auth, API, model, email, payment, storage, domain, or third-party tool costs unless quoted otherwise. Final scope, timeline, payment structure, and care plan are confirmed before build starts.

    Fit check

    Good fit, bad fit.

    Good fit
    • You need a browser-based tool, not just a website.
    • The app has one clear audience.
    • The first version can focus on one core workflow.
    • Users need to submit, search, calculate, train, generate, track, or view something.
    • You want SEO, analytics, and conversion paths built in from the start.
    • You can provide examples, rules, and app goals.
    Bad fit
    • You need an iOS or Android app.
    • You need a full enterprise platform.
    • You want every feature in version one.
    • You need regulated medical, legal, or financial decisions.
    • You cannot define the first user flow.
    • You want unlimited support without a care plan.
    Guardrails

    What this does not do.

    • No iOS or Android apps.
    • No giant enterprise rebuilds.
    • No guaranteed traffic, users, sales, rankings, or funding.
    • No regulated decisions.
    • No unlimited features in version one.
    • No vague app idea without a scoped workflow.
    • No permanent support without a care agreement.
    You keep ownership

    You keep ownership of the scoped app logic, content, and business materials created for the build. Third-party platform ownership depends on the tools used.

    FAQ

    Common questions.

    What is a custom web app?

    A custom web app is a browser-based tool built for a specific business workflow. Users open it in a browser to submit, search, calculate, train, generate, track, or view something. It is more useful than a website and more productized than a single automation.

    How is a web app different from a website?

    A website explains what you do. A web app lets someone do something. If a visitor needs to check eligibility, calculate a quote, submit details, practice a skill, search a library, generate leads, track progress, or move through a workflow, a custom web app may convert better than another static page.

    Does Evoworks build iOS or Android apps?

    No. Evoworks builds browser-based web apps that work on desktop and mobile browsers. We do not build native iOS or Android apps.

    What can a web app include?

    Public SEO pages, the core app workflow, user accounts, an admin dashboard, AI features, payments, analytics, and handoff docs. Final scope depends on the job the app needs to do.

    How much does a custom web app cost?

    Starter Web App from $3,000 setup. Standard Web App from $5,000 setup. Advanced or SaaS MVP is a custom quote. Optional care from $199 per month. Client pays for required hosting, database, auth, API, model, email, payment, storage, domain, or third-party tool costs unless quoted otherwise.

    Can the app include SEO, analytics, payments, or AI?

    Yes. SEO pages, analytics, payments via Stripe, and AI features can all be scoped into the build when they support the app's core job.

    Who owns the app logic and content?

    You keep ownership of the scoped app logic, content, and business materials created for the build. Third-party platform ownership depends on the tools used.

    Scope a web app for a real business workflow.

    Apply with the user, the action, and the result you want. Evoworks confirms fit, scopes a useful v1, and ships before anyone commits to a larger build.
