This sample app is concerned with mortgages. The user enters the value of the
mortgage, the down payment, the tenure and the annual interest rate. The app
then calculates the amount due each month.
How do you convert a simple spreadsheet calculating a commission to an app?
There's more than one way to do it and what you choose depends on your
preferences. Our new sample app demonstrates three strategies.
Our latest sample app converts spreadsheet column data to formulas for use
with drop-down fields. This app uses regular expressions heavily and this post
explains in detail how it was built.
Our new sample app is a calculator for shared household expenses. It enables
users to define recurring expenses in one panel and fields for those expenses
are then created in another panel. This app demonstrates formula-driven
labels.
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).
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.
