Log a test
Type the results, or the drops you counted with a Taylor K-2006 kit and let the app do the math. It says what’s in range and what to add.
Is the water ready? H2Oracle knows.
Log your tests, chemicals and swims for the pool and the hot tub. H2Oracle works out whether the water is safe to get in, how much chlorine or acid to add, and when it’ll need more, learned from your own water.
What it does
Add chemicals
As you type the amount, it shows what it will do to the water and how long to wait before swimming.
Log swims and soaks
People use up chlorine. Say how many were in and for how long, and the estimates allow for it.
Predictions
After a few weeks of tests it learns how fast your water uses chlorine and drifts in pH, and suggests a dose before it runs low.
Pool and hot tub
Each has its own history, ranges and answer. Chlorine or bromine, salt water or not.
Water and filter upkeep
Knows when the filter needs a rinse and when the hot tub’s water needs changing, from how much it’s been used.
Share with your household
Keep everyone’s phones in step, with no accounts: invite each phone with a QR code that works once.
Reminders that fit
A reminder to test on the days you choose, a re-test after chemicals, and a nudge when a treatment step or the filter is due.
