We build apps for iPhone and Android, from the first idea to launch on the App Store and Google Play, and keep them running after launch.
Our apps are used every day by students, patients, drivers and customers of local businesses. If you already have an idea, send it over and get an estimate of scope, timeline and cost.
Every one of these apps is live and doing a real job for a client. They are four very different types of apps, so chances are one of them is close to your idea.
01
Education app · iOS & Android
An app for a school that prepares students for university entrance exams in chemistry and biology. Students get video lessons, practice problems, tests, quizzes, past entrance exams and digital textbooks, available anytime.
02
Audio app with in-app purchases · iOS & Android
A quit-smoking app built around a guided 90-minute audio hypnosis session. Users buy three months of access directly in the app, through App Store and Google Play billing.
03
Discount card app
An app for a medical discount card that is valid for 365 days at more than 500 private healthcare providers: clinics, labs, opticians, dental and veterinary practices. Companies can also offer the card as an employee benefit.
04
Loyalty app with map · Android
An app for drivers and customers of local businesses. It brings together coupons, loyalty stamps, partner discounts and rewards, a QR code for redeeming offers and a map with navigation to partners, while drivers also get a digital service log and registration renewal reminders.
We don't work from a template. We combine the features that solve real problems for your users, and behind the app we build the backend, the database and the admin panel.
Video lessons, tests, quizzes and materials that unlock for each user.
In-app purchases of content or access, as in Online Hypnosis.
Loyalty stamps, discounts, QR codes and rewards for returning customers.
Partner locations on a map, with navigation to each one.
Time slot selection, confirmations and reminders for users.
Sign in with email, Google or Apple, plus history and settings.
Alerts about new offers, reminders and messages to your users.
The database, content management and user data behind the app.
If you already have a website or online store, we can connect the app to it.
For most businesses we recommend launching on both platforms. With a cross-platform approach, one codebase powers both versions, so the second platform doesn't cost twice as much.
Android apps are published on Google Play and can also be distributed as an APK file for internal use. We test on a range of manufacturers and screen sizes.
iOS apps are published on the App Store, where Apple reviews every version. Before we submit the app for review, you test it yourself through TestFlight.
Starting with a single platform makes sense when you want to validate an idea quickly and at a lower cost, or when you know exactly which phones your users have.
We build apps in Flutter, from a single codebase for iOS and Android. That gets you onto both platforms faster, without duplicate development, and keeps long-term maintenance simpler.
The same Flutter code runs both the iPhone and the Android version, so your users get a consistent experience on every device.
For most business apps the performance difference isn't noticeable, while new features, bug fixes and ongoing maintenance are simpler and more cost-effective.

Every project goes through the same six phases, so you always know what's being worked on and what comes next.
You tell us about your idea, who your users are and what the app needs to solve. You get a ballpark estimate of scope, timeline and cost.
Together we list the screens and features for the first version. Based on that, you get a written proposal with a fixed price and timeline.
We design every screen and build a clickable prototype you can tap through like a finished app, before a single line of code is written.
We build the app, the backend and the admin panel. Along the way you get test builds on your own phone, via TestFlight for iPhone and Google Play internal testing for Android.
We test on real devices, prepare the store listing, screenshots and metadata, and submit the app to Apple and Google for review.
After launch we monitor crashes and performance, keep the app compatible with new iOS and Android releases and add new features.
The price depends mostly on the number of screens and features, the backend and admin panel, and integrations with other systems. You get an exact price once the specification is done.
| App type | Example | Starting at | Estimated timeline |
|---|---|---|---|
| Simple app | Content, catalog, user accounts, notifications | [[UPIŠI]] € | [[UPIŠI]] weeks |
| App with payments, a loyalty program or a map | Subscriptions, coupons and stamps, partners on a map | [[UPIŠI]] € | [[UPIŠI]] weeks |
| Complex platform | Two user types, real-time bookings, multiple integrations | [[UPIŠI]] € | [[UPIŠI]] weeks |
We handle the launch, from preparing the store listing and screenshots to answering Apple's and Google's questions during review. All we need from you are the accounts and your company details.

Accounts in your company's name. We recommend opening the Apple and Google accounts in your company's name, so the app is always yours.
Privacy policy. Both stores require a public privacy policy page and a description of the data the app collects.
Review before release. Apple reviews every new version, and Google may require closed testing before a public release.
Billing for digital content. Subscriptions and digital content go through Apple's and Google's billing systems.
An app needs regular updates even when you're not adding new features. Maintenance covers system, security and functional improvements.
We monitor how the app performs and keep it compatible with new iOS and Android versions and with app store requirements.

Not every business needs an app, and we'll tell you so on the first call. An app pays off when the same people come back to you often. A website is enough when they visit once or only occasionally.
If your customers reach out once a year, you'll be better served by a fast website or online store and solid SEO.
Our apps are live and in use, and you can download and try them before you get in touch.
We handle the app, backend, admin panel, website, hosting and launch, so you don't have to coordinate multiple vendors.
Before we start, you get the list of screens and features, the price and the timeline in writing.
The price depends on the number of screens and features, the backend and admin panel, and integrations with other systems. A simple app starts at [[UPIŠI]] €, and you get an exact price in a written proposal once the specification is done.
A simple app takes [[UPIŠI]] weeks, while more complex apps take [[UPIŠI]] months. Add a few days for App Store and Google Play review.
Yes. We build apps for iPhone and Android phones, usually both versions from a single codebase. Sa Hemijom Na Ti and Online Hypnosis are both live on the App Store and Google Play.
Yes. If you want to validate your idea faster and at a lower cost, we launch on one platform first and add the second once the app proves itself.
Yes. We work remotely with clients from other countries, in English, through video calls, email and shared project tools. The whole process, from the first call to the app store launch, works the same wherever you are.
You need an Apple Developer account ($99 per year), a Google Play developer account ($25 one-time), a privacy policy and your company details. For an organization account, Apple also requires a D-U-N-S number. We take care of preparing the app and submitting it for review.
Yes. Digital content and subscriptions are billed through Apple's and Google's in-app purchase systems, as in Online Hypnosis. Physical goods and services can be paid by card through a payment provider of your choice.
Yes. We build the server, the database and an admin panel where you manage content, track users and send notifications yourself, plus a website for the app if you need one.
Yes. We keep the app compatible with new iOS and Android versions, fix bugs, maintain the server and add new features as agreed.
A PWA is a website that can be added to a phone's home screen and behaves much like an app. It costs less than a native app, but it isn't listed on the App Store, and on iPhone it has limitations with notifications and device access. It works well for simple tools and informational apps.
Send us a short description of your idea using the form below: what the app should do, who it's for, and your rough budget and timeline. We'll get back to you with an estimate and a suggested next step.
Briefly describe what the app should do and who it's for. We'll reply with an estimate of scope, timeline and cost, with no obligation.
