💼 Client

Reely is a Finland educational technology start-up focused on creating accessible language learning tools. Their mission is to make learning English as engaging and effective as possible.

🦄 Product

The English learning process is often perceived as monotonous and unstimulating resulting in poor learner engagement and low retention rates. In response to evolving consumer preferences, which increasingly favor short-form video content like that found on TikTok, the startup aimed to revolutionize the learning model. Their innovative approach seeks to blend education with entertainment, transforming the English learning experience into one that is not only enjoyable but also more accessible and engaging.

🎯 Audience

The primary target audience for Reely includes students, professionals, and casual learners worldwide who are non-native English speakers looking to improve their language proficiency in a funny manner and without a lot of efforts.


🛠️ Technical

  • Background fast video download;
  • Create a responsive and accurate algorithm to adapt to users' language proficiency;
  • Ensure seamless cross-platform compatibility for a consistent user experience;
  • Curate a diverse and engaging library of video content;
  • Implement an intuitive and user-friendly interface for learners of all ages and backgrounds.

🖌 Design

Inspired by the engaging and dynamic style of TikTok, the design for the app adopts a similar aesthetic approach. A decision was made to incorporate a dark theme and vivid color palette, mirroring TikTok's captivating visual experience. The app also maintains the side navigation feature found in TikTok videos, allowing for an intuitive user interface that is familiar to a wide audience. The design of the application is platform agnostic, ensuring a consistent and seamless user experience across all devices without specific adaptations for iOS or Android platforms.

📱 Platforms

The app was initially developed for Android and iOS to capture the vast mobile user market. However, plans to incorporate a web platform were established to facilitate a closed alpha phase, with the intention of developing a more comprehensive web-based learning environment in the future.

⚙️ Process

The client presented a concept influenced by the visual style of the TikTok app. The design should visually mirror TikTok but with a wholly unique user experience. Once the initial design was established, we developed prototypes to bring our concepts to life. These prototypes were then subjected to the testing phases, where functionality and user engagement were evaluated. After multiple iterations and refinements, the app underwent a final review before its launch to guarantee that all objectives were met. The development timeline was 3 months.

After successfully developing the app, Reely initiated a closed alpha testing phase. Unfortunately, the performance metrics during this phase did not meet expectations, leading the startup to decide to cease operations.
