Win

Win is an all-in-one utility app whose unit converter covers not just the common categories but the detailed ones that single-purpose converter apps often get wrong or leave incomplete. The speed category includes km/h, mph, meters per second, feet per second, knots, and Mach, covering road travel, aviation, nautical navigation, and physics problems in one place. The length category spans millimeters, centimeters, meters, kilometers, inches, feet, yards, miles, and nautical miles, more than enough to handle construction, navigation, science, and casual travel questions. The metronome offers a completely different kind of utility: set your tempo between 20 and 300 BPM, use tap tempo to find your rhythm, select a time signature (2/4, 3/4, 4/4, 6/8), hear the accent on beat one, and switch to vibration mode for silent practice. Win works entirely offline with no account needed, install it once and all 10 tools are available from the start.
