From body assessment spreadsheet to app.
A body assessment spreadsheet in Excel does the job at first: you type in the skinfolds and the formula returns body fat percentage. PounceFit started out as a spreadsheet like that and now does the same work as an app, with each client's history, progress charts and a PDF report ready to send.

Spreadsheet or app?
| Spreadsheet | PounceFit | |
|---|---|---|
| Formulas | You build, check and lock the cells. | Jackson & Pollock, Guedes, Faulkner and Durnin & Womersley built in. |
| History | One tab or one file per client. | One record per client, with every assessment. |
| Progress | Charts built by hand. | Ready-made charts and two assessments side by side. |
| Report | Copy, paste and export. | Short or full PDF with your brand. |
| Sending | Attach it to an email. | Email from your Gmail without leaving the app. |
| Next assessment | In a separate calendar. | Reminder on the Today screen and in Google Calendar or Outlook. |
| Backup | Copy the file by hand. | Automatic every week, password protected. |
What stays the same.
You measure with a caliper and type in the values. It works offline, and the data stays on your computer, just like your spreadsheet.

Frequently asked questions
Does PounceFit import my Excel spreadsheet?
No. You add your active clients in the app, and each new assessment goes straight into their history, with charts and a PDF.
Will the results match my spreadsheet?
If your spreadsheet uses the published formula for the same protocol, they should match. If it uses a custom formula, results may differ. Check with the Jackson & Pollock 7-site calculator.
