## What is Dipgauge?

Dipgauge is an offline fuel-tank gauge and reorder planner for heating oil and propane.

Enter a stick dip in inches, a tank-top float dial, or a propane gauge percentage and Dipgauge turns it into gallons, percent full, fill amount, reorder timing, delivery cost, and planning notes. It works on device with no account, no hardware, no ads, no tracking, and no internet requirement.

What Dipgauge does:

- Converts stick dips, float dials, and propane gauge percentages into gallons
- Includes published-style charts for common 275, 330, 500, 550, and 1000-gallon oil tanks
- Supports common propane tank sizes
- Builds custom charts from tank shape and dimensions
- Shows a live tank diagram with current level and reorder threshold
- Learns burn rate from your reading history
- Supports weather/season planning and degree-day K-factor analysis
- Estimates days to reorder, days to empty, order-by date, and next-fill cost
- Logs deliveries with gallons, price per gallon, supplier, and total cost
- Shows monthly consumption and seasonal fuel spending
- Exports readings and delivery history as CSV
- Includes illustrated guides and a glossary
- Adds a supplier call sheet for cleaner fuel-company ordering

New in 2.1, the Supplier Call Sheet turns your current plan into a concise order summary: gallons now, suggested order size, estimated cost, order-by date, lead-time risk, and a plain-language call script. It helps you make a cleaner phone call and remember what to confirm before scheduling a delivery.

Dipgauge gives estimates to help you plan. Always leave a safety margin and follow your fuel supplier's guidance.
