Thanks for checking out UnitMaster — a small tool built with one goal: convert essential units quickly without bloated UI or heavy scripts. I created UnitMaster because most converters either feel outdated, slow, or overloaded with ads and unnecessary features. This one focuses purely on fast loading, clarity, and getting an answer instantly, whether you're on desktop or mobile. It also supports an EN/JA toggle so it works comfortably for both global and Japanese users. This release is intentionally minimal, but not finished. The next updates will focus on: - improving the mobile layout and spacing - expanding the unit list slightly (still lightweight) - adding a simple batch-convert option - introducing a compact “recent history” view - refining auto-calculate behavior and UI timing If you have any feedback — missing units, UI improvements, or device-specific issues — I’d genuinely appreciate it. The tool will keep improving step by step while staying fast and simple. Thanks for trying it out!
