Calculator App

Calculator App

At FormLoop you can launch your calculators as calculator apps for your customers or sales staff. You can choose and configure a calculator and use the code (supplied after pressing the getcode button) as a button linking your user direct to a mobile version of the widget. The mobile version works offline and ships with an automatic backbutton for your user to get back to your page, also the formloop webaddress is hidden in the browser.
Our widgets and apps are developed in html5 and are made in responsive HTML design. This means that the menu together with the mobile calculators will work on all phones (android, ios, windows phone and more), tablet computers (ipad and more) and of course it will work and behave as usual on desktops and laptops.
