Useful apps.
Made for the task.

We make apps that help with everyday work, starting with Chrome extensions.

Our first app is a Chrome extension.

Sheet Change Detector

A spreadsheet changed.
Find out where.

Compare two ranges in Google Sheets, or a saved snapshot with the current range. Review changes to values and formulas, cell by cell.

A small change, made visible.Sample data: a supplies budget

Two changed cells in a sample budget, comparing a saved snapshot with the current range
Cell	Before	After
B4Value	312.40	431.90Value changed
B8Formula	`=SUM(B2:B6)`	`=SUM(B2:B7)`Formula changed

Two cells. Two different changes.
See the new amount and the extended formula.

Illustration only, not a live spreadsheet tool. No sheet access or uploads on this website.

That’s the approach behind The apps done well: focus on a useful task, make the result easy to understand, and keep the next step clear.

Sheet Change Detector starts with a familiar question: what changed in this spreadsheet?
