What you keep, what changes on day 15
The trial is the whole product, so it ends on a date rather than feature by feature. Here is exactly what that day changes.
You keep
- Your account, and every pool, test and dose you saved. Nothing is deleted, and it all stays readable.
- The dosing calculator — free forever, for anyone, account or no account.
Until you subscribe
- New dose recommendations stop — poolcntrl stops telling you what to add.
- Reminders stop arriving. Strip scans, photo diagnoses, the support chat, logging a dose or a service, and adding or editing a pool all wait.
Subscribe whenever you are ready and everything switches back on, exactly where you left it.
A year of poolcntrl costs less than one visit from a pool service.
A pool service tells you the water is fine. poolcntrl shows you — every reading, every dose, and what it was measured against.
- Pool service
- $1,800a year, year-roundAbout $150 a month while the pool is open — roughly $750 in a five-month season.
- Doing it yourself
- $150–$800a yearChemicals only. It depends on your climate, your pool and your season.
- poolcntrl Pro
- $49.99a yearTells you exactly what to add, how much, and when.
poolcntrl Pro is $49.99 a year — the one that keeps the other two from being a guess.
Start free for two weeks — no cardClose the pool and poolcntrl goes quiet — then wakes up in spring.
Closing up for winter? A guided checklist walks you through winterizing, and the moment you mark the pool closed the reminders stop — no nudges about water nobody is swimming in. When the forecast warms up in spring, poolcntrl asks whether you are ready to reopen and walks you back from green to swimmable, one test at a time.
