Web app
Runs in the browser on desktop and mobile and can be added to a phone’s home screen as an icon. The fastest route to first users.
App development: from an idea to an app on your phone
Before It Was Cool designs and builds mobile and web apps for businesses and new ventures across Slovakia: from the idea and screen design to an app people install on their phones. AI speeds up development; people decide and check.
30 minutes, online, no obligation.
How is an app built with AI?
AI writes first drafts of the code, tests and copy, so a working app comes together faster and real people try it sooner. People decide what the app does, how it looks and what gets released. A person reviews every change, and automated tests check it.
The result is a normal app: on the web, on iPhone and on Android, from one codebase. The difference is that you reach a first version you can show customers sooner.
What we build
iPhone and Android app
One codebase packaged for the App Store and Google Play, with native features such as haptics and speech. We help with the store release too.
Prototype to test an idea
A working first version with what matters most, so you can try the idea with people before investing more.
What app development includes
From the first sentence about your idea to an app people download and keep using.
Scope of the first version
Together we decide what the first version must do and what can wait. A smaller scope means real users try the app sooner.
Screen and experience design
How people move through the app, what they find where and why they come back. Design that follows your brand identity.
Content and copy
In-app copy, guides and expert content. Where needed, an expert checks it, for example a native speaker for a language app.
AI-assisted development
AI speeds up writing code and tests; a person decides and reviews. We never put personal data or your company’s confidential information into AI tools without your consent.
Testing
Automated tests on every change and checks on real phones. For Ovečka that means about 700 checks and a simulated learner going through a whole year.
App Store and Google Play release
Getting the app ready for review, plus the store description, screenshots and keywords, so people can find it.
Case study · in development
Ovečka: an app for learning Slovak
We are building our own app the same way we offer to build yours. Ovečka teaches Slovak to English speakers, and its little sheep, Ovečka, walks with them across Slovakia from Bratislava to Košice, one lesson at a time.
The app is in development. We use and test it every day, and a native Slovak teacher checks its content.
- 27 stops on a journey across Slovakia
- 2,679 words in 67 packs and 35 grammar lessons
- speaking, listening and stories at every stop
- one codebase for the web and iPhone
After release: updates, accounts and marketing
New versions
Release is not the end. We add fixes, features and content version by version, based on what users show us.
Accounts in your name
We set up App Store, Google Play and other accounts in your name. What you receive at handover is set out in the written scope.
Getting the app found
Store listings, an app website, SEO and GEO and ads under one roof.
Who our app development is for
A good fit if
- you have an app idea and want to try it with real people as soon as possible
- you need an app for customers or your own team and want to talk directly to the people building it
- you want one partner for the app and for getting people to hear about it
Less suitable if
- a good website is enough: website design is faster and cheaper
- you do not yet know what problem the app should solve: start with an intro call and a prototype, not a full app
- you want a finished app without testing it with people: even with AI, a good app needs user feedback
How app development works
- 01
Intro call
30 minutes, online. What the app should solve, for whom, and how we will know it works.
- 02
First-version scope
Features, screens and platforms. You get the scope and price in writing.
- 03
Design and prototype
Screen designs and a first clickable version for you and your people to try.
- 04
Build and testing
AI-assisted development, automated tests and checks on real phones.
- 05
Release and new versions
Release on the web or in the stores, then new versions based on feedback.
What drives the price of an app
Every app is different, so we price by scope. It depends on:
- the number of screens and features
- web, iPhone, Android or all of them
- sign-in, payments and integrations with other systems
- who prepares the content and in how many languages
- App Store and Google Play release
- care and new versions after release
You get the scope and price in writing before work starts. You can also start with a smaller prototype.
App development: common questions
How much does an app cost?
It depends on the number of screens and features, the platforms, sign-in and payments, content, and whether you want a store release. We send you the scope and price in writing after the intro call. You can also start with a prototype.
How long does app development take?
It depends on the scope. With AI we reach a first version you can show people sooner than with traditional development. The dates for each step are in the written plan.
Do you build apps for iPhone and Android?
Yes. From one codebase we build a web app plus iPhone and Android apps, and help release them in the App Store and Google Play.
How does AI help, and is it safe?
AI writes first drafts of code, tests and copy. A person reviews every change, and automated tests check it. We never put personal data or your company’s confidential information into AI tools without your consent.
Who owns the app?
You do. We set up App Store, Google Play and other accounts in your name. What you receive at handover is set out in the written scope before work starts.
Can you help people find out about the app?
Yes. Store descriptions and keywords, an app website, SEO and GEO, ads and social media under one roof.
Got an app idea?
On the intro call we work out what the app should solve and suggest the smallest first version that proves it.
