How to open on iPhone or Android

iPhone / iPad: In WhatsApp, share the attachment → Save to Files. Import or open the saved .html file in an offline HTML viewer that supports JavaScript. Enable JavaScript in that app if needed. Files / Quick Look and WhatsApp previews may display the page without running the calculator. Opening local HTML directly in Safari is not a reliable file-opening route.
Android: Download the attachment. From Files / Downloads, use Open with and select a browser or HTML viewer that supports local HTML and JavaScript. If your browser is not offered or only displays a preview, import the file into a compatible offline HTML viewer.
Look for “Interactive · calculations work offline”, then move a slider. If you received a ZIP, extract it first. Once the file is in a compatible viewer, calculations need no internet or hosting.

Viewer support varies. No HTML setting can enable scripts in a preview that blocks them. Sharing to WhatsApp needs internet; printing, copying, and saving depend on your viewer.

Use Save interactive copy to keep the current clinic numbers in a new HTML file. Reopening the original file starts with the values stored in that file.

Illustrative estimate only. Monthly value adds diagnostic revenue, avoided remake costs, and optional chair-time value. It is not accounting profit or guaranteed cash flow. Avoid counting the same saved chair time in both remake savings and chair-time value. Running costs, tax, and finance charges are not included.
