## What is WellMeter?

WellMeter measures the depth to water in a well using nothing but your iPhone's speaker and microphone.

Hold the phone over the well opening and tap Measure. WellMeter plays short chirps down the casing, listens for the echo off the water surface and times the round trip. It keeps measuring until the reading converges, then shows the depth with its spread and a confidence score.

FEATURES
• Depth to water in metres, with ± spread and confidence
• Temperature compensation for the speed of sound
• Pipe inner-diameter setting that keeps the chirps inside the casing's clean frequency band
• Waveform and echo-correlation plots, so you can see what was detected
• On-device history of every measurement
• Works offline — nothing leaves your iPhone

FOR A GOOD READING
• Point the phone's bottom edge (speaker and microphone) straight down into the centre of the well.
• Hold it still a few centimetres above the opening for about 10 seconds.
• Turn the volume to maximum and measure in quiet conditions.

PRICING
WellMeter is free to download. Start the free 15-day trial inside the app to use every feature. When the trial ends, taking new measurements requires a one-time purchase; your saved history stays available either way. No subscription, no ads, no account.

Accuracy depends on the well: casing diameter, obstructions, pumps and background noise all affect the echo. WellMeter is a measuring aid, not a certified instrument.
