When calculating something on your smartphone, entering each number one by one can be quite a hassle. This app eliminates the need to enter numbers when you want to convert. It's useful when you want to quickly get a rough calculation result. "New Conversion Method Proposal Q&A" Q1: How is this different from using a calculator? A1: With a calculator, you press each number key one by one. You have to be careful not to press the wrong key... If you use "Rough Conversion," it's easy: just align the red indicator with the scale and the converted value will appear. Q2: When repeating similar conversions, it's a hassle to have to re-enter numbers multiple times... A2: With "Rough Conversion," you can just slide the indicator along the scale and "see consecutive conversion results immediately." Q3: But it can't do a variety of calculations, right? A3: It can't do a variety of calculations like a calculator. However, if you register the conversions you frequently use in advance, you can use the "Rough Conversion" function to create something like your own "personal slide rule." [Features] - Easily convert values ​​without having to enter them yourself; simply slide your finger across the red indicator on the panel. - Quickly see approximate calculations. - You can freely customize the units you want to convert in advance. - You can also switch the conversion range, allowing you to convert over a wide or narrow range. - You can also freely set the title of the app's conversion screen. - The values ​​and units you set in the settings screen will remain the same the next time you launch the app. * The default setting is "tsubo" ←→ "m2" when converting land area.
