Smart Tank Diary

**Smart Tank Diary** helps you keep track of your household's rainwater tank, record water-level changes, and understand how long your remaining water may last based on your recent usage.

Whether you collect rainwater or manage a household water tank, Smart Tank Diary provides a simple way to maintain your own records of tank capacity, water readings, consumption patterns, and rain refills.

### Set Up Your Tank

Enter your tank's full capacity so recorded readings can be checked against the amount of water your tank can actually hold. Set up your tank before beginning to track its water history.

### Record Water Readings

Keep a history of your tank's water readings to understand how its level changes over time. Use your records to follow water consumption and distinguish changes caused by water use from those associated with refilling.

### Track Rainwater Refills

Record how rain contributes to your tank's water supply. The app can identify a rain-fill separately from an ordinary draw-down using the recorded level history, helping you review how much your own catchment has contributed.

### Estimate Days of Water Remaining

View an estimate of how many days the remaining water may last based on your tank's recent consumption history. The estimate uses the tank's own recorded usage rather than a fixed assumption about how much water a household consumes.

### Choose Your Preferred Units

Display tank capacity and water measurements in your preferred unit. Choose between litres and gallons to suit your record-keeping needs.

### Configure Low-Water Warnings

Set a low-level threshold for the days-remaining figure. When the estimate falls below your chosen threshold, the app highlights it so you can recognize when your recorded water supply may be running low.

### Use Meaningful Historical Records

Set a minimum number of consumption readings required before a days-remaining figure is displayed. When there are too few recorded readings, the app avoids displaying an estimate based on insufficient history.

### A Simple Household Water Diary

Smart Tank Diary is designed to keep your tank records organized in one place. Review the history of your household's water supply and use your own records to better understand changing consumption patterns.

### Important Limitations

Days remaining is an estimate based on the tank's recorded history, not a guarantee of future water availability. Actual water consumption can change, and rainwater collection depends on rainfall and catchment conditions.

Smart Tank Diary does not provide engineering, plumbing, installation, or water-quality advice. Its estimates depend on the readings and information recorded by the user.
