TEKKAN is a revolutionary archery record-keeping tool that connects to the internet, offering a range of features to assist archers in managing their accuracy and progress. This iPhone app, developed by Ryuto Suzuki, is designed to be user-friendly and provides various tools to support both individual archers and team activities.

With TEKKAN, archers can easily record the accuracy of their shots, including details such as the location of the arrows. It also allows users to add notes about coaching instructions or any other relevant information. The recorded data can then be analyzed through clear and easy-to-read graphs, providing valuable insights into the archer's performance. Additionally, users can add comments to the data for better organization and analysis based on specific keywords.

One standout feature of TEKKAN is its ability to analyze shooting forms. By simply taking a photo within the app, the AI technology analyzes the archer's shooting form and saves it as skeletal data. This enables archers to compare and overlay their shooting forms, not only for self-improvement but also for comparison with friends who are participating in the app's community.

TEKKAN also offers a group function, known as "みん的" (Minnteki), which allows users to share information such as accuracy and attendance within a group. Some of the registered data can be instantly opened in spreadsheet software, such as Google Sheets or Excel, installed on smartphones. Furthermore, TEKKAN allows users to transfer recorded data to their PC, where it can be downloaded in a format compatible with spreadsheet software like Microsoft Excel. This feature ensures that users can access their data from various devices, including PCs, smartphones, and tablets.

TEKKAN promises to continuously provide even more convenient services in the future, making it an essential tool for archery enthusiasts and professionals alike.
