Coblit built the Odważni Migają app for Towarzystwo GEST: a child scans a QR code in the book and watches a video in Polish Sign Language (PJM).
About the project
We built a mobile app that links the book with videos: the child points the phone camera at a QR code in the book and instantly watches the chosen word or sign in Polish Sign Language. The book also hides special signs that the child tracks down like a detective and collects in the app.
Project journey
The book “Odważni Migają” (“The Brave Ones Sign”) teaches children Polish Sign Language, but a sign is a movement — on paper you can only show a drawing. A parent who doesn't know PJM can't always show the child what the sign really looks like.
Every day without a solution meant more manual work, slower service and missed opportunities.
We built a mobile app that links the book with videos: the child points the phone camera at a QR code in the book and instantly watches the chosen word or sign in Polish Sign Language. The book also hides special signs that the child tracks down like a detective and collects in the app.
The book “Odważni Migają” has gained an interactive companion: reading turns into an adventure, and every sign can be seen in motion.
Who it’s for
We see similar challenges in many companies. If you recognise yourself in this list, this project shows what we can do for you too.
Children's book publishers
Educational and social projectsFoundations and associations
Schools and nurseries
Organisations working for accessibilityCreators of educational materials with video elementsWhy it works
Just scan the QR code to see the sign in motion, without searching for materials online.
The signs hidden in the book encourage the child to come back to reading and look for more.
A parent who doesn't know PJM learns together with the child from the same videos.
One scanner and the video plays straight away, with no accounts or settings.
The app brings Polish Sign Language closer to hearing and deaf children alike, in line with the mission of the Odważni project.
How we ran the project
This is how we worked together on the Towarzystwo GEST (Odważni.org) project: from understanding the processes, through wireframes and architecture, to rollout and further development.
We talk to the people who will use the system. We map out how processes work today, where time and money are being lost, and how they should work a year from now, once the company has grown.
We build what solves a real problem — not a list of features nobody will use.
We design screens and user journeys in Figma and test a clickable prototype with future users before the first line of code is written.
You see and test the solution at the outset — changes to a mock-up cost a fraction of changes to a finished system. You can order the analysis and mock-ups as a separate stage.
We choose technologies to match the goal, the budget and the systems already running in the company. We design the architecture, integrations and data security so that the system can grow together with the business.
React NativeReact Native Reanimated
Google Cloud Platform (GCP)No costly rework a year later — the system is ready for more users, more data and new features.
We work in short stages and show a working version every few weeks. We launch the features that deliver the biggest savings first.
You have constant visibility of progress, a say in the direction and see the first results sooner.
We test the system, migrate the data, launch it in the production environment and train the team in day-to-day use.
A smooth start without downtime — from day one the team knows how to work in the new system.
After launch we monitor operation, respond to tickets under the SLA and extend the system with further features and automations.
One partner from idea to ongoing development — you are never left alone with the system.
