We build websites, e-shops and apps
Apps people use every day
We build B2C mobile and web apps for communities, lifestyle, sports, hobbies and digital services. From rapid prototype through UX, design and backend all the way to publishing on the App Store and Google Play.
What decides success
An app lives or dies on whether the user opens it a second time
- 8 in 10 users delete an app after first use if they don't see clear value
- Without clear onboarding, free users don't stick around
- Without notifications and recurring value, users disappear
- Apps that solve a concrete problem quickly and conveniently win

What is a custom web application?
A custom web application is software that runs in the browser and handles a specific job inside your company. Unlike a website, which mostly informs, an application processes data, enforces rules and replaces manual steps in spreadsheets and e-mails.
Companies typically use one for job tracking, bookings, approvals, reporting or giving customers access to their data. Only the people who should can log in, and each user sees exactly what their work needs.
Custom mobile and web app development
Custom app development means a product built around one specific user problem, not a universal template. With B2C apps what matters is whether the user opens it again after the first time, so we start with a prototype and test it before we code anything.
We focus on apps people use in their free time, from communities and lifestyle to digital services. For us development does not end at the store launch: we watch how the app is actually used and keep growing it based on data.
Who we build for
Apps for people, not corporations
We focus on B2C apps, products users download themselves and use daily or weekly in their free time.
Communities and content
Places where people meet around a shared interest, create content and share opinions.
Community app · Forum · Marketplace · Local groups
Digital services and utilities
Apps that solve a concrete recurring task, booking, payments, managing something in daily life.
Booking · Planner · Personal finance · Smart home
How we work
From idea to an app that lives beyond launch
We don't want to ship an app that ends up in a drawer. We run every phase to minimise the risk of launching something nobody will use.
UX and prototype
We start with a prototype and test it with real users. Unnecessary features get cut before we code them.
iOS, Android and web
Native, hybrid or PWA, we pick the technology based on goals and budget. For most B2C a single codebase covers both platforms.
Backend and API
We build a reliable backend with authentication, notifications, payments and integrations with external services.
Onboarding and retention
Push notifications, emails, in-app messages. We help users understand the app and come back.
Store publishing
We prepare screenshots, copy and icons for the App Store and Google Play. We help with the review process.
Analytics and iteration
We track real user behaviour, measure key actions and improve the app based on data.

Phone consultation · 30 minutes
We'll call you at the chosen time. We'll chat about the project and by the end you'll know what makes sense, for how much, and when we can realistically ship.

Custom web application development from idea to first version
A custom web application makes sense when spreadsheets, emails or an off-the-shelf boxed system are no longer enough. devBoys helps design and build applications for internal processes, customer portals, booking systems, order tracking, accounting integrations or automation of repetitive work.
We build web applications and portals on Laravel, which suits long-term systems with user roles, permissions and integrations with other tools.
We start practically: first we describe the problem, the users, the key screens and a minimal first version together. That way we quickly find out what brings real business value and what can wait.
Typical parts of the cooperation:
- a short analysis and scope proposal,
- a prototype of the main screens,
- a first usable version of the application,
- integration with existing systems,
- long-term development based on real usage.
When a custom web application pays off
- when you repeatedly rewrite data between systems,
- when customers or employees need their own portal,
- when an off-the-shelf system cannot handle your specific process,
- when you want to start with a smaller first version and grow it based on results.
Frequently asked
Answers to what we hear most often
Can't find your question? Write to us, happy to answer it during a free consultation.
How much does custom app development cost?
The first version of a mobile app is priced by scope, larger web and mobile apps individually. We always fix the price in the quote after a free consultation, so you know upfront what you will pay.
How long does app development take?
We deliver the first version of a mobile app in a matter of weeks from prototype approval; for larger apps it depends on scope. You get the exact deadline in writing in the quote.
When does a custom web app pay off for a company?
The moment employees keep rewriting data between spreadsheets and systems, customers need their own portal or online booking, or an off-the-shelf system cannot handle your specific process. A well-chosen first version pays for itself in saved time, not years later.
What if I only have an idea and no brief?
That is the most common situation clients come to us with. In a free consultation we describe the problem, the users and the main screens together. From that we build a prototype and a minimal first version proposal, so you get the brief from us, including a fixed price.
Do you build native apps or hybrid?
Both. For most apps we recommend React Native: one app runs on both iOS and Android, development is faster and cheaper. If the project needs native performance, such as heavy graphics or augmented reality, we go native.
Do you support the app after launch?
Yes, launch is where the work really starts. We offer monthly development and support packages: we fix bugs, add features and react to user feedback. The app grows together with your business.
What experience do you have with app development?
We have been developing since 2017, with 119 completed projects behind us, from websites to apps. A public example is Shooting Diary, a mobile app for iOS and Android that we keep developing based on user feedback. You can find more of our work in the references and case studies on devboys.cz.
How do I contact you when I want a quote for an app?
Call +420 601 386 720, write to info@devboys.cz or fill in the form at the bottom of the page. The first consultation is free and non-binding.
What does the collaboration look like and who delivers what?
The first call is non-binding, we discuss goals and scope. Then we prepare a budget and timeline. You provide the inputs (copy, photos, branding); we can supply or arrange anything missing.
How much will it cost?
Price depends on scope and complexity. After the consultation you get a concrete quote with either a fixed price or an hourly estimate. No hidden items, everything is in writing.
Can the solution be extended later?
Yes. Every project is built to scale with new features, languages or integrations. The most common additions are booking, payments, a customer zone, or hooks into accounting and CRM systems.
Will you also manage the solution long-term?
Gladly. We offer monthly development and support packages so the project keeps improving and responding to user needs.
