What We Build
Three Ways to Get Your App
Not every business needs an app in the stores. We help you pick the option that solves the problem for the lowest cost.
iOS and Android Apps
An app installed on your customers' phones, with push notifications, camera, location and login. We build both versions from a single codebase, which keeps the cost down, and publish them on the App Store and Google Play.
PWA: The App You Install From the Browser
A web app customers add to their home screen like any other app, without going through the stores. It is the fastest and cheapest way to have an app, and updates reach everyone instantly.
Real Projects
Platforms Already in Production
Both are live and used every day by our clients' customers.
Pricing and Timelines
How Much an App Costs
Web Arts reference prices, published so you know what to expect before getting in touch. After a short call, you receive a fixed price in writing for your app.
| App Type | Price | Typical Timeline |
|---|---|---|
| Simple web app or PWA | €2,000-€7,500 | 4 to 8 weeks |
| Custom web platform (bookings, client portal, payments, SaaS) | €5,000-€20,000 | 8 to 16 weeks |
| iOS and Android app | €6,000-€25,000 | 8 to 16 weeks |
| Hosting, backups, maintenance and updates | from €49/month | Monthly |
The exact timeline is written into the proposal. Store developer accounts are registered to your company (Apple: €99/year; Google Play: $25 one-off). Want to compare with other companies? Read our guide to app development costs in Portugal, with typical market prices.
Before You Choose
Native App, PWA or Web App: Which One?
It is the question we hear most before a quote. The answer depends mostly on how often your customers will use the app.
| iOS and Android app | PWA | Web app | |
|---|---|---|---|
| Where it is installed | App Store and Google Play | Home screen, from the browser | Not installed; opens in the browser |
| Web Arts price | from €6,000 | from €2,000 | from €2,000 |
| Notifications, camera, GPS | Full access | Partial (limited on iPhone) | Limited |
| Shows up on Google | No (stores only) | Yes | Yes |
| Updates | Go through store review | Instant | Instant |
| Best for | Frequent use and loyalty | Testing an idea on a small budget | Platforms, portals and internal tools |
Rule of thumb: if customers will open the app every week, a store app pays off. If they will use it now and then to book, buy or check something, a web app or PWA does the job for less than half the price. Many projects start as a web app and move to native once there are enough users to justify it.
Examples
Apps We Can Build for You
- Booking and reservation platforms for clinics, salons, gyms, coworking spaces and home services, with reminders and upfront payment.
- Client portals where customers check orders, invoices, documents or the status of a job.
- Custom management software that replaces spreadsheets and chat threads: orders, stock, teams, projects or routes.
- Ordering and loyalty apps for restaurants and shops, without delivery-platform commissions.
- Startup MVPs: the first version of your product, ready to test with real users and show to investors.
- Marketplaces and subscription platforms, with online payments, user profiles and an admin dashboard.
No Surprises
Our Three Guarantees
An app is a bigger investment than a website, so these commitments are in writing in every proposal.
Fixed Price in Writing
Before we start, you receive a proposal with the final price, the features included and the timeline. If you want to add something new mid-project, we quote it separately and only proceed with your approval.
Revisions Until Approved
We show you the app screens in a clickable prototype before writing code, and revise them until you say they are approved.
30 Days of Free Fixes
After launch, any bug you find in the app during the first 30 days is fixed at no cost. Message us by email or WhatsApp and we take care of it.
How We Work
From Idea to Published App
Call and Proposal
We learn what problem the app must solve and for whom. We reply to quote requests within 1 business day and send a proposal with features, a fixed price and a timeline in writing.
Prototype and Design
We design the main screens as a clickable prototype, so you can try the app before any code exists, and refine it until you approve.
Development in Phases
We build the app in short phases and show you each one working, so you see progress and can change course early, while it is still cheap.
Launch and Support
We deploy the app, publish it on the stores, connect payments and your domain, and fix anything needed for 30 days at no cost.
What You Get
An App Ready for Real Customers
Login and Roles
Customer, staff and admin accounts, each seeing only what they should, with data protected in line with GDPR.
Online Payments
Card payments and local methods such as MB WAY, with invoices and subscriptions when your business model needs them.
Admin Dashboard
A dashboard where your team manages bookings, users, content and stats day to day, without depending on us.
Ready for Google and AI
The public pages of your app are built to be found on Google and cited by AI assistants, with structured data from day one.
Frequently Asked Questions
Still Have Questions?
How much does it cost to build an app in Portugal?
At Web Arts, a simple web app or PWA costs €2,000-€7,500, a custom web platform €5,000-€20,000 and an iOS and Android app €6,000-€25,000. The exact figure depends on the features and is fixed in writing in the proposal. See how this compares with the market in our app cost guide.
How long does app development take?
As a guide, a simple web app or PWA takes 4 to 8 weeks, and a custom platform or an iOS and Android app 8 to 16 weeks. The exact timeline for your project is written into the proposal.
Should I build a native app, a PWA or a web app?
If customers will use the app every week and you need push notifications, the camera or GPS, an iOS and Android app pays off. If the goal is booking, buying or checking information, a web app or PWA does the job for less, works on any phone and can rank on Google.
Do you publish the app on the App Store and Google Play?
Yes. We handle submission and approval on both stores. The developer accounts are registered to your company: Apple charges €99 a year and Google a one-off $25.
Can we start with a simpler version?
Yes, and it is usually what we recommend. We start with an MVP that covers the essentials, test it with real users and add the rest in phases, each with its own fixed price.
Can we work together remotely?
Yes. We are based in Almada, Lisbon, and work with clients across Portugal and Europe over video calls and async updates. Every phase ends with a working demo you can try.
Can't I just build the app myself with AI?
For a prototype, yes: AI tools generate screens in minutes. For an app with real customers, payments and personal data, you still need security, GDPR compliance, performance and store publishing done properly.
