Pool Predictor Pro is owned by Insight Solutions LLC, the data controller for your personal data.
It forecasts when your pool or spa's water chemistry will next need attention, so you test and dose on a schedule instead of guessing. Enter your pool details and a water test, and it projects each chemical forward day by day using your pool's profile and your local weather.
No. Use any test kit or strips and enter the numbers you have. The app supports common kits, and its accuracy tightens with more precise ones (like drop-based FAS-DPD). You can even read a test strip with your phone's camera.
A short setup wizard asks for your pool's size, surface, sanitizer, equipment, sun and environment, fill-water source, and test kit, then your first water test. That profile lets the app fill in anything you didn't measure and start predicting right away.
Just one. It predicts from a single reading, filling in unmeasured values from your profile. Accuracy and confidence improve as you log more tests, because it learns how your pool actually behaves.
It runs a daily simulation of your whole water chemistry starting from your latest test, accounting for chlorine loss, pH and alkalinity drift, sun and UV, temperature, rain, and any products you've logged. It flags the first day a value is set to drift out of range: your "next check" date.
Yes. It measures your pool's real chlorine-loss rate from your test history and uses that instead of a generic assumption, so forecasts get more tailored the more you test.
It reflects how much the app trusts a forecast, based on how complete your data is and how consistent your pool has been. Logging more tests and entering measured (rather than estimated) values raises it.
New weather, a new test, or a logged treatment all update the simulation. A hot, sunny stretch shortens the timeline; rain or a fresh dose shifts it.
With your ZIP code, the app pulls your local forecast: UV, temperature, rain, humidity and wind. Offline or without a location, it falls back to a seasonal estimate for your area, so predictions still run.
Free, combined and total chlorine, pH, total alkalinity, calcium hardness, cyanuric acid (CYA/stabilizer), salt, water temperature, TDS and phosphates, plus overall water balance (LSI).
When a value is off, it reverse-calculates the exact amount of your preferred product to reach target. For example, "add ~1.2 qt of muriatic acid to lower pH to 7.5", sized to your pool's volume.
CYA (stabilizer) shields chlorine from the sun but also weakens it, so higher CYA needs more free chlorine to stay effective. Saltwater pools hold chlorine at a lower ratio than manually chlorinated ones. The app applies these pool-industry ratios automatically.
Yes. A tiered picker goes Category → Type → strength or a specific branded product, and dosing uses that product's real concentration.
Some additions dissolve slowly. Stabilizer, chlorine tabs and salt take days to fully mix in, so the chart ramps them up gradually and won't suggest re-dosing what's still working in.
Common ones: high chlorine demand, chloramines (high combined chlorine), a CYA crash (a sign of possible ammonia or bacteria), green/yellow/black algae, cloudy water, scaling or corrosive water, over-stabilization, foaming and staining.
If chlorine falls when it should have risen, that usually signals unusually high demand, such as an organic load or chloramines burning through it. The app flags this and suggests testing combined chlorine and shocking to satisfy the demand.
Combined chlorine (chloramines) is "used-up" chlorine that still shows on a total-chlorine test; above about 0.5 ppm it causes the strong chlorine smell and eye and skin irritation. Breakpoint chlorination means shocking high enough to burn it off, and the app calculates the dose.
When logging a test, you can flag what the water looks like: cloudy, green, foaming and more. Detected issues appear as a dismissible card and in an Issues Log, where you can add your own notes, log the suggested fix, or mark it resolved.
The app can send an on-device reminder on your next-check date, so you test right when it matters.
Not yet. Reminders are on-device notifications today. Email and SMS alerts are planned.
Yes. Pool Predictor Pro requires an account, so we collect your email address and an account identifier. Once you are signed in the app works fully offline, with your pools, water tests and logs stored on your device.
On paid plans, anything you log offline is queued and uploaded the next time the app is online, so nothing is lost. On the Free plan your data stays on that device only, so if you decide you don't like the app you can remove all your data.
Your device is the source of truth, so the app keeps working without a signal. On paid plans your pools, tests and logs are also synced to our cloud so you can use them on more than one device. On the Free plan they stay on your device only.
Cloud sync is a paid feature. On a paid plan your pools, tests, treatments and issues sync to your account and across your devices, keeping the most recent change. On the Free plan nothing is synced. Settings → Back up & transfer moves your data to a new phone on any plan, including Free.
Occasionally, yes, and you can stop it in one tap. Alongside the account mail you'd expect (address confirmation, password resets, notices about changes), we sometimes email about a chemical, a piece of equipment or an offer that suits your pool, picked from the profile and readings you entered.
What we don't do is sell or share your details to make that happen: there are no ad networks, no advertising identifiers and no third-party tracking in the app, and your email address and pool data never go to an advertiser or list broker. Every one of those emails has an unsubscribe link, and using it doesn't affect your account, your subscription, or the service mail above.

The free tier is there to let you try the app properly before paying: one pool, two water tests and two treatment logs, with the full forecast engine, charts and diagnostics. Nothing is a mock-up. The forecast you see is the real one.
The one thing two tests can’t do is teach the model how fast your pool actually drifts. That comes from comparing several tests over time. Until then it uses industry-standard rates, so the prediction band stays wider than it would be and the confidence score can’t reach its top range.
Pro removes those limits: unlimited water tests and treatment logs, up to two pools, and cloud sync across your devices. With enough history behind it the model calibrates to your pool, which narrows the prediction band and lifts the confidence score. It's $24.99 a year, billed through Google Play. No credit card is needed to use the free tier.
The free tier covers a single pool or spa, and the Pro plan covers up to two. A shared account for pros and fleets is in development.
Subscriptions are billed by Google Play. Cancel any time in the Play Store under Payments & subscriptions → Subscriptions. Deleting your account does not cancel a subscription. See our terms.
Make sure the guide matches your test kit, use even natural light, avoid shadows and glare, hold the camera steady, and fill the sample area. Re-scan if a color looks off, since lighting is usually the culprit.
No. It's a planning and guidance tool, not a replacement for professional service. Always handle and store pool chemicals according to their label instructions.
