Hot tub readings you can check before every stay
Each rental's tub in one app, with the source and age of every reading, and an alert when a reading leaves its range.
All your rentals in one app
With one to a few properties, each tub sits in one list with its status and the age of its readings.
A connection to rental booking software comes later.

What “in range” means
The app shows a rental tub as In range only when all three of these hold.
- pH7.2 to 7.8Measured, under 10 minutes old
- Water temperatureAt or below 104 °FMeasured, under 10 minutes old
- SanitizerFree chlorine or bromine in its rangeFrom a hand test logged inside its validity window
How the app decides In range
One hand test on its own never makes the whole tub In range. A reading more than 10 minutes old is marked Stale, and its status shows Unknown.
The pH range follows CDC vacation-rental guidance. The 104 °F limit is from CDC hot-tub guidance and the U.S. Consumer Product Safety Commission.
From CDC guidance for vacation rentals
“Monitor and maintain adequate disinfectant levels, even when the hot tub isn't in use.”
Full service or do it yourself
A local Hydara partner installs the unit, and Hydara watches its readings either way.
Full service through a local partner
Your partner makes the service visits, handles the chemicals your plan includes and logs hand tests at each visit. Alerts go to your partner.
Do it yourself
You log the hand tests and buy chemicals outside the app. Alerts go to you.
Test the water by hand before guests use the tub; automatic dosing does not replace it.
The controller assists. You remain responsible for the water in your tub.
