We build business applications: internal systems instead of spreadsheets and customer portals, with mobile apps for iOS and Android as our second line. A web application from EUR 3 690, a mobile app from EUR 2 090, and we fix the price after the analysis. We have been programming since 2017 and have 119 completed projects behind us.
Why build the application now
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.
A business application proves itself by whether it saves people work in the very first week, not by the number of features. Custom development means a product built around one specific problem, not a universal template, so we start with a prototype and test it before we code anything.
Most often we build applications for companies: an internal system instead of spreadsheets, a customer portal, bookings or orders connected to stock and accounting. Mobile apps for iOS and Android are our second line. Development does not end at launch, we watch real usage and keep developing.
Most often we build applications for companies with an established operation, where orders, stock and customer communication hold together only thanks to spreadsheets and the discipline of the people. Three situations clients come to us with most often.
Orders, stock and planning in one place. Everyone in the company sees the current status, nothing is entered twice and the owner has an overview without calling around. For the manufacturing company SQAIR systems we connected the website to ChatGPT, so they request product changes from the chat.
Order tracking · Stock and issue slips · Capacity and shift planning
The customer logs in, orders, follows the status of the order and downloads invoices or documents without calling the office. We took over the Fyzioklinika portal with online patient booking from another supplier, stabilized it without any downtime and kept developing it.
Customer portal · Orders for wholesale customers · Bookings and approvals
One app for both iOS and Android that complements what already works in the company: bookings, a loyalty program or a tool for people in the field. We took Shooting Diary from design to App Store release and keep developing it based on user feedback.
Bookings and loyalty program · Apps for field workers · Collecting data and photos on site
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.
We start with a prototype and test it with real users. Unnecessary features get cut before we code them.
Native, hybrid or PWA, we pick the technology based on goals and budget. For most B2C a single codebase covers both platforms.
We build a reliable backend with authentication, notifications, payments and integrations with external services.
Push notifications, emails, in-app messages. We help users understand the app and come back.
We prepare screenshots, copy and icons for the App Store and Google Play. We help with the review process.
We track real user behaviour, measure key actions and improve the app based on data.
A custom mobile app from design to release on the App Store. Training records, firearm and ammunition tracking and smart reminders for service and document expiry. 100% offline.
A web app built around your processes, or a mobile app for iOS and Android as an add-on to your business. We build a new one or take over an in-progress project.

devBoys are programmers you talk to directly. Since 2017 they have been building custom applications for web, iOS and Android: internal systems, customer portals, bookings. They have 119 projects behind them, for example the Shooting Diary mobile app for sport shooters, an e-shop that hands orders to the warehouse for the Náměsíčník publishing house and an MCP server for the manufacturing company SQAIR systems. Mobile apps from EUR 2 090, web apps from EUR 3 690. Contact: +420 601 386 720, info@devboys.cz.
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:
Can't find your question? Write to us, happy to answer it during a free consultation.
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.
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.
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.
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.
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.
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.
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.
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.
Yes. First we go through the code and the access, write down what works, what is broken and what needs finishing, and give you a fixed price. The app keeps running the whole time. Then we continue one-off or in a monthly package from EUR 290, as described on the Long-term development page.
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.
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.
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.
Gladly. We offer monthly development and support packages so the project keeps improving and responding to user needs.
30 minutes on a call is enough for you to leave with a clear idea of scope, timeline and price.
Websites, e-shops and apps connect into one ecosystem. Clients often start with one and add the others over time.
Practical articles on the topic so you have more to go on before the first call.
Your message will be read personally by me or someone from the team and we'll get back to you to talk through the details. No sales reps, straight to a practical technical consultation that moves you forward.
