Frequently asked
Questions, answered.
Does Skimmer sync between my iPhone and iPad?
Yes. Skimmer uses iCloud (CloudKit) to sync between your devices automatically — no separate account required. Your data is yours, on your devices.
Do I need an internet connection to use it?
No. Skimmer works offline by design — log a water test or maintenance task at the pool deck without LTE. Updates sync next time you're connected.
What pool types does Skimmer support?
All of them — chlorine, saltwater, bromine, mineral, and more. Skimmer pre-loads the right maintenance schedule for your pool type, and you can add any custom task.
Will my service history really add value at resale?
Yes. Pool inspectors and home appraisers increasingly ask for documented maintenance history. A complete chemical log and equipment service record is a genuine selling point. Skimmer produces a clean, professional PDF you can hand to your buyer.
Does Skimmer track water chemistry?
Absolutely — that's the heart of the app. Log pH, free chlorine, combined chlorine, total alkalinity, calcium hardness, cyanuric acid, and salt. Skimmer shows you balanced, drifting, or out-of-range status and trends over time.
Can I track multiple pools?
Yes. Vacation home, rental, HOA — track as many pools as you have. Pro tier supports unlimited pools and equipment.
Can I cancel my subscription?
Anytime — directly in iOS Settings → Apple ID → Subscriptions. We don't add friction. If you ever want out, you're out, and your data stays on your device.
Do you store my data on your servers?
No. Skimmer has no backend. Your data lives on your device and (optionally) in your iCloud — we can't see it, and no third party can either.
