Features
Read your gauge, type the number, done
Read your rain gauge each morning and enter the total in seconds, with quick-add buttons for tenths and a one-tap "no rain" entry — because a dry day is a record too.
A calendar that turns blue on rainy days
See the whole month at a glance. Rainy days turn blue on the calendar, with daily and monthly bar charts and a running cumulative curve from January 1st.
Compare this August with last August
GaugeBook lines up the same month across every year you've recorded, so "drier than last year" becomes a number, not a feeling.
Millimeters or inches, your choice
Switch freely between millimeters and inches. Every entry stays on your device — no account, no subscription, no ads, no network at all.
Real numbers from your own garden or farm
GaugeBook is not a weather app. It never uses forecasts, radar, or GPS to guess your rainfall — only the true numbers you read from your own gauge.
Your backyard's real rainfall — measured, not estimated. GaugeBook is a quiet daily journal for people who read an actual rain gauge: no forecasts, no radar, no GPS guesses. Just the true numbers from your own garden or farm.
Read your gauge each morning, type the number, done. Today's total sits front and center in big, clear digits, with quick-add buttons for tenths and a one-tap "no rain" entry — because a dry day is a record too.
Watch the month and year add up: a calendar that turns blue on rainy days, daily and monthly bar charts, and a running cumulative curve from January 1st.
Then ask the question every gauge owner asks: how does this August compare with last August? GaugeBook lines up the same month across every year you've recorded, so "drier than last year" becomes a number, not a feeling.
