About this app

Backyard Sap Tracker is a simple, privacy-first tool for hobby maple syrup makers. Track everything from tap to bottle on your phone with no account required.

## Dashboard

View sap flow days, gallons collected, and estimated syrup output at a glance. Switch between a daily timeline and calendar view to see weather conditions, collection totals, and sap flow predictions.

## Tap Management

Add and manage individual taps by tree species and location. Track installation dates and monitor per-tap collection volumes.

## Sap Collection

Log daily sap collection by tap with optional Brix readings. See per-collection syrup estimates based on the Rule of 86.

## Boil Tracking

Record boil sessions with pre-boil and post-boil volumes. Track syrup output across the season.

## Weather Integration

Automatic weather data from Open-Meteo or the National Weather Service. Sap flow conditions are calculated from daily highs and lows -- freeze overnight followed by a thaw above 32F marks a sap flow day. Historical 5-year averages extend the forecast out to 45 days.

## Privacy

All data is stored locally on your device. No account, no cloud, no tracking. GPS coordinates are only used to fetch your local weather forecast. Export your data anytime as JSON or CSV.
