Technology boutique · Portugal

Apps and websites, crafted end to end.

We design and build mobile apps, web apps and websites — Flutter for iOS and Android, Ruby on Rails for the web and the backend. A small team that takes your product from first sketch to the stores, and stays with it after launch.

Our apps are live on the App Store and Google Play.

What we do

Three things, done properly.

We keep our toolbox deliberately small, so we know every part of it deeply.

01 Flutter

Mobile apps

One codebase, native look and performance on iPhone and Android. We design it, build it and publish it.

  • iOS and Android from a single codebase
  • Calendar, contacts, maps and offline support
  • App Store and Google Play publishing and updates
02 Ruby on Rails

Web apps & backends

Back offices, client portals, APIs and SaaS products, on a framework that lets us move fast without cutting corners.

  • Admin back offices your team can run on its own
  • APIs that power your mobile apps
  • Accounts, payments and third-party integrations
03 HTML · CSS · JS

Websites

Fast, responsive websites that load quickly, read well on any screen and are easy to keep up to date.

  • Responsive and accessible by default
  • SEO, analytics and Tag Manager set up
  • Hosting, domains and ongoing care

The whole product, one team.

Most of our projects need more than one piece: an app, the system behind it and a website to point people to. We build all of them, so nothing gets lost between agencies.

How we work

From idea to launch, without surprises.

  1. 1

    Discover

    We talk through your goals, your users and your constraints, then send you a clear scope and estimate.

  2. 2

    Design

    Screens and flows you can click through and comment on before a line of code is written.

  3. 3

    Build

    Short iterations with regular test builds on your own phone, so you see progress as it happens.

  4. 4

    Launch

    Store submission, server deployment and analytics. We handle the paperwork and the review process.

  5. 5

    Evolve

    OS updates, fixes and new features. We maintain what we build, year after year.

About Tekinsight

Small by design.

Tekinsight is an independent technology boutique. When you work with us, you talk directly to the people designing and writing your software. No account managers, no hand-offs.

We also build and run our own apps. Sagax Games and Guia TV keep us honest about what it really takes to ship, support and grow a product that people use every day.

  • Direct

    One conversation with the people doing the work, from kickoff to launch.

  • End to end

    Design, mobile, backend, web, stores and hosting, under one roof.

  • Focused

    Flutter and Rails, known deeply rather than a long list of tools known a little.

  • In it for the long run

    We maintain what we ship, and our client apps return edition after edition.
