Type one number. Read them all. Unitap converts a value into every unit of the same category at once. There is no "from" and "to" to pick — the moment you type, the answer is already on screen. ■ Pin what you use Tap the star and that unit stays right under the input field in large type. From the second time on, you just type the number: cups → ml and tablespoons for cooking, inches → cm for DIY. It becomes your own conversion sheet. ■ 14 categories, about 195 units Length, mass, temperature, area, volume, speed, duration, data, pressure, energy, power, angle, fuel efficiency and number bases (2 / 8 / 10 / 16). Traditional Japanese units (tsubo, jo, go, sho, monme, shaku and more) are included. ■ Conversions work offline, no account Every conversion happens on your device, so it works the same in airplane mode or underground (only the ad banner uses the network). No sign-up, no login. ■ Made for moments like these - A recipe says "1 cup" and "350°F" and you think in ml and °C - Overseas listings and drawings use inches, lb and sq ft - You need GB vs GiB, or kB vs KiB, converted correctly - Imperial units slow you down every time ■ How to use 1. Pick a category from the chips at the top 2. Type a value (tap the unit button to change the input unit) 3. Tap a row to copy the value, tap the star to pin it Numbers are formatted with grouping separators and sensible significant digits, and unit names follow your device language.
