You carry us in your pocket. Mobile apps and business systems.
A two-person studio from Lodz, Poland. We design and build mobile apps, business systems, websites and online stores. Twelve of them are in use with our clients today, and two more are our own products.
Four areas we work in.
Mobile apps and business systems are the main specialisation. Websites, stores and integrations run on the same terms: as a standalone project or as part of a larger system.
Mobile apps
iOS and Android come from a single codebase, which shortens delivery and lowers the cost of maintaining both versions. We run the project from the first sketch, through testing on physical devices, to release on the App Store and Google Play. After release we handle updates and reported issues.
Business systems and dashboards
The panel brings into one view the data currently spread across spreadsheets, inboxes and separate programs: orders, stock, documents and billing. We design it for use on a phone, because some decisions are made away from the office, and we separate permissions by role.
Websites and online stores
We build sites for loading speed and for search visibility, both planned from the start of the project rather than bolted on after launch. A store is connected to stock and payments so that quantities and amounts agree without anything being retyped.
Automation and integrations
We connect systems that have not been exchanging data, and move into them the tasks repeated at the same hour every day. We make sure the data agrees on both sides and that an outage in one service does not stop the other.

Mobile apps, business systems, websites and stores. For each one we describe what needed doing and how it works today.
What we connect projects to.
We take on payments, delivery and store releases. Below are the tools we work with most often. Each project page shows exactly what was connected in it.
Mobile apps
One codebase for iOS and Android, native modules where they are needed, and release in both stores handled on our side.
- Expo
- React Native
- TypeScript
- Kotlin
- Swift
- App Store
- Google Play
- Supabase
Online stores
Payment stays in the shop, with no hop to an outside domain. BLIK, Przelewy24, cards and the Apple Pay and Google Pay wallets run through a single provider, and parcels go to a locker or a courier.
- Stripe
- BLIK
- Przelewy24
- Klarna
- InPost
- ORLEN Paczka
- DPD
- DHL
Websites
Traffic measurement from day one, a map for directions, form messages delivered to the inbox, bot protection on the form, and campaign measurement when the company runs one.
- Next.js
- Vercel
- Google Analytics
- Tag Manager
- Google Maps
- Meta Pixel
- Resend
- Cloudflare
Four stages of a commission.
The order is the same for a website, a store and an app. A conversation needs no specification and no technical knowledge, only a description of what the thing should do.
Conversation and quote
We establish what exactly gets built, by when, and which materials we need to start. The answer is a fixed price for an agreed scope, with no commitment on the client's part.
Design for approval
Layout and copy go for approval before any code exists. Changes cost least at this stage, which makes it the moment for comments rather than assumptions.
The build
Progress is visible in the client panel: stages, payments and the current version. Comments are attached to a specific section, so nobody has to explain over the phone which part is meant.
Launch and support
After publication we stay with the project. For twelve months faults are fixed at no additional cost, and further development is quoted separately.
Six things in every quote.
They need no separate order and no remembering. Without them a project is not ready to hand over, so they are part of the scope by default.
Visibility in Google
Addresses, headings, descriptions and structured data prepared from the start of the project, not added after launch.
Legal compliance
Separate consents, a privacy policy and terms drawn up for the data the project actually collects.
Readable for everyone
Contrast, keyboard operation and alternative descriptions checked against the standards that apply in the European Union.
Client panel
Access to the brief, the contract, payments, stages and revision requests for the whole duration of the commission.
Review before launch
Before publication we check access to data, forms and payments, and confirm every fix by trying to get around it.
A year of warranty
On everything we built, counted from the day of launch.
We build the apps and systems for you.
We work with marketing agencies, studios and companies that get asked for apps or systems but have nobody to build them. There are two commercial models, and in both the scope and the price are agreed before the work starts.
Client referral
We sign the contract and run the project from the first conversation to release, including support after launch. The company or person who passed the contact on receives an agreed percentage of the project value. It is settled once the work is finished and the client has paid for it.
Work under your brand
We quote the scope, your company signs the contract with the client and keeps the relationship. We invoice you, not the client. We appear under your brand, with an NDA where one is needed, and report progress in a form that can be passed to the client without rewriting.
Two people, from the first email to release day.
Kontaktio is a two-person studio from Lodz, Poland. There is no customer service department and no intermediary passing your notes along.
You speak directly to the people who design and build your system. Most questions get an answer the same day, and the work we deliver carries a twelve-month warranty.
