Add steppers to number fields to make it easy to change their values using
plus and minus buttons. Sliders take up more space, but make it even easier to
experiment. There are also new formula functions, improved support for
embedding apps in websites and a rewritten tour template.
If only some users need to use a large number of fields, start off by showing
only a few and give users the ability to add or remove fields using plus and
minus buttons. We demonstrate this technique using a sample app that
calculates a grade point average (GPA).
Sliders enable users to rapidly change the value of a number field within a
defined range. On mobile devices with cumbersome on-screen keypads, we expect
sliders to become the preferred way of experimenting with numeric inputs.
Steppers enable users to quickly increase or decrease numbers using dedicated
buttons, displayed next to the value. A variety of properties are available
for customizing steppers, including minimum and maximum values.
The new formula functions TONUMBER, TOLOGICAL and TOTEXT make it easy to
convert values to numbers, logical values and text strings, respectively.
Converting numbers stored as text to true numbers was previously impossible if
the number had a fractional part.
The tour template shows off many of Calcapp's features and has been completely
rewritten. The new tour demonstrates steppers, sliders, number formatting,
date calculations, cross-references and more. There's even a color selector
for the background color.
Remove the navigation bar from shared apps that have only one panel simply by
ensuring that you don't type a panel title. This change especially benefits
apps embedded in other websites.
The Share app button now reads Update app if your app has been shared. Changes
you make to an app never go live for your users until you give the go-ahead by
pressing the button.
To get the number of hours, minutes or seconds between two dates, subtract one
date from the other and use the HOUR, MINUTE or SECOND formula functions.
HOUR won't return a number greater than 23 and MINUTE and SECOND won't return
a number greater than 59. Read on to learn how to fix this.
If you can't run your app because a message asks you to reload the app, don't
press the button. Ignore it for a few minutes and then press OK on the new
message that has appeared.
Calcapp enables you to create apps that might otherwise have been
created using a spreadsheet. Create apps yourself without
time-consuming and expensive custom software development.
