How it goes today
How PoolDose works
01 · Test
Dip the strip, then squint at the bottle’s color chart in the sun.
Snap one photo of the wet strip on your phone.
02 · Read
“Is that green or yellow-green?” Call it a guess.
Calibrated reading: FC 3.2 ppm, pH 7.4, TA 90 ppm.
03 · Dose
A scoop. Maybe two. Whatever the bucket says.
1 lb 4 oz cal-hypo — sized to your 12,500 gal.
04 · Result
Hope it clears before the party on Saturday.
Balanced water, no overshoot, no $400 panic.

No more $400 algae panic.

How it works · Procedure

Four steps, no chemistry degree.

PROCEDURE 01

Dip & snap

Dip your strip, take a photo. PoolDose reads the pads against a calibrated chart — no squinting at the bottle.

PROCEDURE 02

Get your dose

Exact amounts in cups and pounds for your volume and your chemical types — liquid, tabs or cal-hypo.

PROCEDURE 03

Log & trend

Every reading saved automatically. Watch FC, pH and TA drift over the season before they become a problem.

PROCEDURE 04

Open & close

Seasonal checklists that tell you what to add and when — from spring open to winter close.

Lab notes

Honest answers.

Q: Where do I get PoolDose?

On Google Play. It runs on Android phones and tablets and is free to install — open play.google.com/store/apps/details?id=com.pooldose.app, or search the store for PoolDose.

Q: What’s free and what’s Pro?

Free gives you the manual dose calculator for one pool, your last 7 readings, and 3 photo strip scans to try. Pro unlocks photo reading day to day, unlimited pools, the full water history, and the seasonal open and close programs.

Q: How many strip photos can I read?

Three on the free plan, in total. Pro reads up to 20 photos a day — more than a full service round needs, and the cap is what keeps the reading engine fast and accurate for everyone.

Q: Which test strips does it read?

The common 6-in-1 and 7-in-1 strips sold in big-box and pool-store kits: free chlorine, total chlorine, pH, total alkalinity, calcium hardness and cyanuric acid. You can also type readings in by hand, on any plan.

Q: Does it work for salt pools?

Yes. A salt chlorinator still comes down to the same free chlorine, pH and stabilizer numbers, and PoolDose doses for those the same way — salt is one of the parameters it tracks.

Q: What does Pro cost, and can I cancel?

€8.99 a month, €39.99 a year, or €89.00 once for lifetime access — all billed through Google Play, VAT included. Subscriptions renew until you cancel, and you cancel them in Google Play, not in the app.
