Hi @noppanut15, your project sounds fantastic! To help you expand depthviz’s compatibility, I recommend focusing on parsing FIT, SDE, and XML files first, since these are the most commonly exported formats from Suunto devices, including the Suunto Ocean. You might want to use open-source FIT parsers (like FitSDK or fitdecode) and analyze sample SDE/XML structures to build robust import logic. Also, reaching out in freediving and Suunto forums with a quick upload form (Google Form or GitHub issue template) might increase contributions. Keep up the great work—this tool could be a real game-changer for the freediving community!
