Mobile apps that people actually use.
MARQIO designs and builds mobile apps for iPhone and Android from one codebase, for customers or for staff. Along with the app we deliver an admin, a connection to your data and publishing on the App Store and Google Play. Slevy a Akce, an app we built, is actively used by more than 15,000 people today.
Who it is for
- Customers call you for information they could look up themselves on their phone.
- You have a web system and want customers or field staff to see the same data on their phones.
- You want your own app on the App Store and Google Play without paying two teams for two platforms.
- The app needs content refreshed every day, and you don't want to fill it yourselves every day.
- You work with sensitive data and need it to stay on the device.
What you get
Send an enquiryAn app for iPhone and Android
One codebase for both platforms, with a natural feel on each. We designed ZEUS Core App for one-handed use.
A connection to your data
The app uses the same data as your web system. What a sales rep enters in the CRM, the customer sees on their phone.
A content admin
You manage banners, campaigns, scheduled publishing and notifications yourself from the admin; at Slevy a Akce, separately for Czechia and Slovakia.
Sign-in, notifications and consent
Sign-in with Google and Apple, notifications based on the user's interests (never at night) and consent under GDPR and Apple's rules.
Publishing on the App Store and Google Play
We prepare releases for both stores and handle review. Later versions are released so they keep working for users on older versions of the app.
AI inside the app
An AI assistant that gives customers quick answers to everyday questions, or AI that runs on the phone with no internet, as in Bodka.
How we work
Intro call
We get back to you and set up an intro call. We discuss who the app is for, what it connects to and whether it is public or internal. Then we propose an approach and budget based on what you need.
Screens and data design
We design the main screens and check where the app gets its data: from your system, from an admin or from the user.
A prototype on your phone
We start with a prototype you can try on your own phone. ZEUS Core App first ran on sample data, and in the next stage we connected it to the live system.
Release and further versions
We handle App Store and Google Play review, prepare guides for your team and, after launch, release new versions based on what users actually use.
Technology
What drives price and timeline
- A public app for customers or an internal one for staff: a public app also needs clear onboarding, consent and store review.
- How many platforms: in our experience a mobile app adds roughly a third to a half of extra work on top of the web, not double.
- Connections to your system, payments or Google and Apple sign-in.
- Admin and content: who fills the app and whether content should be prepared automatically.
- AI in the app, and whether it runs in the cloud or on the device.
- Every project is different. We propose scope, timeline and budget based on what you need.

Frequently asked questions
Yes. MARQIO builds mobile apps for iPhone and Android from one codebase, typically in React Native. Both Slevy a Akce and ZEUS Core App were built this way and feel natural on both platforms.
Yes. MARQIO prepares releases for both stores, handles App Store and Google Play review and sets up monitoring. Slevy a Akce is in both stores, and we release new versions on an ongoing basis.
The length of development depends on scope, the number of connections and whether the app is public or internal. The ZEUS Core App customer app went from design to release-ready in four months. MARQIO starts with a prototype on your phone, which helps you decide how to continue.
In MARQIO's experience a mobile app adds roughly a third to a half of extra work on top of a website, not double. Web, iOS and Android come from one codebase; the extra is mainly preparing store releases, review and testing on phones. Every project is different; we propose a budget based on what you need.
Yes. ZEUS Core App uses the same data as the ZEUS Core web system: what a sales rep enters in the CRM, the customer sees on their phone. New web features reach the app without doing the work twice.
MARQIO handles consent under GDPR and Apple's rules from the first version. At Slevy a Akce notifications follow the user's interests and never go out at night. For sensitive data, AI can run on the device itself: in the Bodka app neither audio nor transcript leaves the phone.
