# Subtract Measured Empty-Bag Tare From a Community Cleanup Weigh-In — Free

A cleanup total weighed in bags includes the bags themselves. Use a measured tare and the number actually on the scale to produce a transparent net-mass receipt without exaggerating the collected material.

**Free and complete.** This guide is a standalone free tool — no account, no card, anywhere. The only paid option is one optional extra outcome: $4 one-time. Nothing in the free tier is gated.

## Who it's for

Community event coordinators reconciling aggregate collection weigh-ins

## What's free

- one complete unwatermarked weigh-in tare receipt run in the app
- three labeled samples and unlimited article-demo calculations
- complete result text and a user-triggered input-state link

## Optional paid add-on

**$4 one-time.**

- unlimited subsequent weigh-in tare receipt app calculations after a local convenience signal
- print the weigh-in tare receipt with visible assumptions and its safety boundary
- CSV of the displayed net kilograms and row workings; conditional estimate uses your manual-retyping minutes
- five local reading summaries (headline/count/time), not saved full inputs or cross-device backups
