You Have the App Idea. We Build It.
From a Cork studio that ships its own software — 15 products built and operated by JMS Dev Lab, seven approved on the Shopify App Store. Web apps from €3,000, with a fixed written quote before any work starts.
Fixed quote up front · You own the code · Weeks, not months · NDA no problem
Most App Ideas Don't Need an "App"
Before anyone quotes you €40,000 for iOS and Android builds, hear this: most ideas are better served by a modern web app — one build that works on every phone, tablet, and laptop, installs to the home screen, and costs a fraction of native development.
The €40k quote trap
Agencies quote native iOS + Android by default because it's two builds instead of one. Unless your idea needs deep hardware access or offline-first operation, you're paying double for no user benefit.
The six-month reveal
The classic failure: months of silence, then a big reveal that misses the point. We build in short cycles — you see working software in the first weeks and steer it while changing course is still cheap.
The lock-in
Some builders keep the code, the hosting, and the leverage. Here, when the build is paid for, everything is yours — full source, on accounts you control. You can leave any time, which is exactly why you won't need to.
From Idea to Live App in Four Steps
Tell us the idea
A short written description is plenty — the problem, who'd use it, and the one workflow that matters most. Not technical? Good: that's our job. Want a mutual NDA first? No problem.
Free, honest review
We come back with what it would actually take — including whether an off-the-shelf tool already does it (we'll say so), and whether you need native or a web app will do.
Fixed quote, in writing
Scope, timeline, and one number. That number doesn't move unless you change the scope. No hourly billing, no surprise invoices.
Built in weeks, owned by you
Working software early, weekly check-ins, and at the end: your app, your code, your accounts. Launch help and a plain-English handover included.
Real Numbers, Before You Ask
Every project gets a fixed written quote. These are the honest starting points:
From €3,000
A focused web app. One core workflow done properly — the spreadsheet replaced, the booking flow, the calculator, the internal tool. About 3–4 weeks.
From €6,000
A multi-feature app. User accounts, payments, dashboards, notifications — the version of your idea people can sign up for and pay for. About 4–8 weeks.
From €12,000
A larger system. Multiple user types, integrations, admin tooling — end-to-end. Still fixed-price, still weeks-per-milestone rather than months of silence.
Full breakdown on the pricing page. For calibration: comparable agency quotes in Ireland commonly run €20,000–€50,000+.
We Ship Our Own Apps — That's the Proof
Anyone can show a portfolio. We can show products we built, shipped, and operate ourselves: 15 of them, including seven approved on the Shopify App Store after independent review of performance, security, and compliance. When we say we know what it takes to get an idea to real users, you can check.
Questions People With App Ideas Actually Ask
How much does it cost to build an app in Ireland?
A focused web app starts from €3,000 (3–4 weeks); a multi-feature app with accounts and payments from €6,000 (4–8 weeks); larger systems from €12,000. Always a fixed written quote before any work starts. Comparable agency quotes commonly run €20,000–€50,000+.
Do I need a native iPhone/Android app?
Probably not — and it's the most expensive assumption in app development. A modern web app works on every device from one codebase and installs to the home screen. Native only earns its cost for deep hardware access or offline-first use. We'll tell you which yours is in the free review.
Who owns the code — and what about my idea?
You own both. The code is yours when the build is paid for — full source, on accounts you control, portable to any other developer. And we're happy to sign a simple mutual NDA before you share the details.
I'm not technical. Is that a problem?
No — most people who bring us an idea aren't. You bring the problem, the audience, and the workflow that matters; we handle the technical decisions and explain them in plain English.
What if my idea already exists as an off-the-shelf tool?
Then we'll tell you, in the free review, before you spend anything. Building custom software you didn't need is the worst outcome for you and — since we publish our reviews' honesty as the whole pitch — for us too.
