HandyKit, a Small Box of Surprisingly Specific Tools

Field notes

The timer organizes parallel countdowns by name and color, adds ring-based progress, and includes alarms; the accompanying guide also mentions +1 minute controls, tab-title countdowns, and desktop alerts. The separate generator previews superellipses from width, height, and exponent n, then exports SVG or DXF for design, laser cutting, and CNC workflows. The site states that the tools work offline and require no sign-up.
