Cool Grader now contains the code to support a trial version of the app, which allows people to download and use it for free before they buy it. The trial version lacks a few important functions but provides some basics and allows the customer use the app before purchasing.
This new version also contains the Conversions system, which performs conversions between various measurement units, such as Area, Heat, Length, Mass, Speed, Temperature, Time, and Volume:
Conversions now supported
Beta-testing for Cool Grader 2.1.0 should be complete by this weekend, and pending evaluation and addressing any outstanding issues, the new app upgrade should be publicly available next week.
Based on user requests, I have added a Search function to the Unit Converter, which allows you to search for a measurement unit or unit category, as shown in the following example:
Starting from any point in the Converter screen, you may touch the [Search] button to bring up the Search display:
You may then type some or all of a unit name or category, and the matching items will automatically display:
In the above example, "mp" was typed into the 'Search for' box, and the units or categories that contained "mp" were automatically listed. When you see the listed unit you are searching for, touch that unit to automatically display it in the Converter:
In the above example, the search item "mile per hour" was selected, and the Converter automatically displayed the "Speed" category and the "Mile per hour" unit.
You may also use the Search function to select a unit category. For example, touch the [Search] button and scroll to the category you want:
If you want to see Mass units in the Converter, touch the "Mass" item in the search list, and the Converter will display that category with the previously-selected units:
The Converter now supports display of a conversion table, which contains a list of converted values for all units in the currently-displayed unit category. For example, if the Temperature category is displayed, a conversion result may be:
You may touch the [Table] button to display a conversion table, which in this example would look like this:
You may then touch any displayed information to copy the table to the clipboard, which allows the conversion table to be pasted into other apps, such as e-mail, a document, etc. The format of the clipboard text in this example is:
Finally completed initial set of conversion units in the Cool Grader Converter! After some finishing touches and additional testing, I will publish the converter in both a Cool Grader update and in a new, separate app, dedicated to unit conversion (name to be announced at publishing). Additional conversion units and measurement categories will be added in future app upgrades.
