Created an App for iOS and Android


PickLang is a language-learning app that helps users learn new languages through interactive lessons and practice exercises based on AI technology. The goal of the app is to provide an engaging and effective language-learning experience for users around the world.
TopUX was tasked with designing the app for both iOS and Android platforms. The app had to be user-friendly, easy to navigate, and offer a variety of features that cater to users' different learning needs.

The challenge

The language-learning market is highly competitive, and our client wanted an app that could stand out from the crowd, and offer features that would set it apart from existing products. They have already created a back-end part of it and a few prototypes of how they imagined their app would look.One of the key challenges was to ensure that the app was suitable for users of all ages and language levels. We had to create an app that was intuitive and easy to use for beginners, while also providing advanced features for experienced language learners.

Our approach

At TopUX, we designed the PickLang app intending to make language learning as engaging and personalized as possible. To achieve this, we utilized a variety of features and design elements to create an app that users would enjoy using and stick with over the long term.
After three test screens, the best one was chosen and our main work began. We conducted a survey of user interests to generate content that best matches their preferences.

User survey

A questionnaire for users about their interests to generate content that best matches their preferences.


An interactive learning system that walks users step-by-step through the basic functionalities of the app, including taking a photo, answering generated tasks based on the photo, completing tasks in the task feed, and trying the test mode.

Gesture-based interaction

A system that allows users to switch between questions or skip tasks with ease, making the process as comfortable as possible.

Task variety

There are two types of tasks. Selecting the correct answer from the options about what is depicted in the highlighted object in the photo, or completing a sentence describing what is happening in the photo. The tasks are generated almost endlessly from a huge database of photos and are personalized to engage the user as much as possible.

AI-generated questions

Users can take their own photos or upload images, and the app will use artificial intelligence to recognize what is in the photo and generate questions.

Gamification system

The app has an extensive gamification system that rewards users with points for completing tasks and tests, increasing their user level, and unlocking opportunities to decorate their profile frames. We also created an achievement system that unlocks animated achievements, creating a competitive effect that motivates users to keep learning.

Progress tracking

Users can track their activity graph and language level growth progress, aided by notifications that remind them of the importance of their studies.


The app offers settings to adjust task difficulty and types, as well as a dark mode option for comfortable use during evening hours.

Client's Feedback

According to PickLang's CEO, "One of the most important things was TopUX worked as a product-driven team. Their suggestions and experience were helpful to us throughout the collaboration." We were delighted to hear that our approach aligned with PickLang's needs and that we were able to provide valuable insights and expertise throughout the project.
