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

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.

Let's talk
Free consultation, let's connect
30 minutes on the phone. Pick a time, leave your number and we'll call you. No strings attached, you leave with a clear picture, not an invoice.
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 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.
Do you build native apps or hybrid?
Both. For most B2C apps we recommend React Native or Flutter, one codebase for iOS and Android, faster development, lower price. If the project needs native performance (e.g. heavy graphics, AR) we go native.
Do you support the app after launch?
Yes, launching is just the start. We offer monthly development and support packages: we fix bugs, add new features and react to user feedback. The app grows together with your community.
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.
