💼 Client

ChaiKoffskiy is a renowned tea house and bakery operating since 2005. The business combines a passion for exceptional pastries with expertise in tea and coffee culture. The company promotes healthy lifestyles through specialized herbal teas that regulate metabolism, enhance physical activity, and boost immunity, complemented by their thoughtfully crafted bakery items.

🙏 Request

The client came to us with a well-established website and online store, looking to develop a mobile application to expand their digital presence and provide customers with a more convenient way to browse and order their products on mobile devices.

During our technical consultation, we advised against building a full-scale app from scratch to save time and budget. Instead, we suggested wrapping their existing online store in a WebView for a seamless, cost-effective transition to a mobile app (webview-based apps are generally cheaper to build than fully native apps​).

🎯 Audience

ChaiKoffskiy's target audience includes pastry enthusiasts, coffee lovers, and busy professionals looking for quality baked goods with convenient ordering options. Client's customers value tradition, quality, and the convenience of having favorite treats delivered to their doorstep.

Challenges

🛠️ Technical

• Implement an efficient solution while keeping development costs reasonable;
• Maintain consistency with the existing website's functionality and design;
• Ensure seamless user experience across different mobile devices;
• Deliver a fully functional mobile app within a tight timeframe.

📱 Platforms

The client required applications for both iOS and Android platforms to reach their entire customer base.

Solutions

⚙️ Process

• We conducted a technical consultation to analyze the client's existing website and requirements;
• After evaluation, we proposed a WebView-based solution instead of a fully native app using the flutter_inappwebview package to enable smooth in-app browsing. The plugin allowed us to embed the website content directly inside the Flutter app ​without rebuilding it from scratch;
• This approach allowed us to leverage the existing e-commerce website while providing a native mobile app experience;
• We added a well-organized native menu within the app for easier navigation, so users can jump to different pastry categories or pages effortlessly;
• The app was tested among different devices in order to check if the UI is consistent;
• The entire process, from the client's initial request to the final publishing of the app, was streamlined and efficient. This allowed us to complete the project within just one week.

👨‍💻 Team

• Flutter Engineer;
• CTO.

✅ Outcomes

• Developed and published both iOS and Android apps within just 1 week;
• Successfully integrated the existing website into a native mobile application;
• Maintained all functionality of the original website while providing the convenience of a mobile app;
• Saved the client significant development time and costs compared to building a custom native application from scratch;
• Provided a seamless shopping experience for ChaiKoffskiy's customers on mobile devices.

An Estonian startup founded by father and son, Marti and Joosep, developed RallyPin to transform the rally spectating experience. Inspired by Joosep’s motorsport journey and feedback from spectators, the app simplifies event navigation with interactive maps, schedules, and unique routing that avoids rally stages. Initially created to solve a personal challenge, RallyPin is now evolving with exciting new features to attract more fans and enhance rally events. Building on their success, the team is now working on an exciting new app for drivers, set to launch soon.

The app consolidates all essential rally information into one seamless platform, allowing users to explore interactive rally maps, discover viewing areas with pictures, and enjoy one-click navigation powered by a unique algorithm that avoids rally stages.

Spectators can track live results, access timetables and entrants, and even see the starting times of the first car and their favorite driver during navigation. RallyPin not only elevates the rally experience for fans but also helps organizers engage more spectators by making events more accessible and enjoyable.

The app operates on a subscription-based model, offering flexible plans such as per rally, 6-month, and 12-month subscriptions, ensuring users can choose what suits them best. The founders actively collaborate with organizations like the Estonian Autosport Union and other key stakeholders to grow the product's reach and impact, establishing RallyPin as an essential tool for the motorsport community.

💼 Client

Fixline LLC, a mid-sized Ukranian transport company, operates several taxi services across Eastern Europe and sought to develop an Uber-like application, Yasha, aimed at streamlining and enhancing the efficiency of their services.

🦄 Product

Commonly used taxi services often lack the versatility needed to meet the diverse needs of Eastern European markets, where local priorities differ. This app addresses this issue by offering customizable features tailored to enhance user experience in these regions.

🎯 Audience

Yasha's main focus is on young locals in urban Eastern European areas, providing them with fast and economical transportation solutions. The app caters specifically to this demographic by offering services in local languages and incorporating features aimed at fostering user loyalty.

Challenges

🛠️ Technical

• Build custom maps with Google APIs integration, beautiful animations and GPS connection;
• Develop an algorithm that determines a user address based on raw coordinates and the internal OSM-database;

• Create an API that integrates partner taxi services so that Yasha can send unprocessed orders to them.

🖌 Design

In the design phase, our task was to make ordering a taxi as easy as possible. The client wanted users to be able to do it in just two clicks. So, we set up the app to remember their past trips and filled in the details for them. We also made sure that the default option was the standard fare. This means users only need to type in their destination and hit "order." We successfully accomplished this task, enhancing the user experience and facilitating quick and seamless bookings.

📱 Platforms

Since the main method for booking taxis is through mobile apps, the customer opted to develop client versions for both Android and iOS to ensure wide accessibility. In addition, there were solutions on the Web to manage the entire app's business logic, including a dispatcher and an admin app.
