How Skimmer stacks up.
Honest, feature-by-feature comparisons against the calculators, chemical-brand apps, discontinued smart sensors, and spreadsheets pool owners already know.
The calculator app the Trouble Free Pool community trusts, built for a single reading at a time, not an ongoing log.
Positioned as a premium, full-service pool app, at a price that's hard to justify against what it delivers.
A free app from a pool-chemical brand, built in part to sell Orenda's own chemical products.
A free app from a test-strip and chemical brand, some versions built around a smart-strip reader that's since been discontinued.
A smart floating water-testing sensor and subscription that, per public reports, was discontinued in 2025.
A smart pool water monitor, hardware plus subscription, that was discontinued, leaving owners without automated readings.
What most pool owners actually use today: free, familiar, and manual all the way down.
