After you send a message.
Every message goes directly to the people who built the site — no triage, no filtering.
For bug reports, we reproduce the issue. For suggestions, we review against the roadmap.
You get a real response within 24–48 hours — not a form letter, not an auto-reply.
We've heard it all — here's what we help with.
Tell us your pool volume, the values you entered, and what the result was. We'll verify and fix it fast.
Missing a tool for calcium hardness, stabilizer, or something else? Let us know — we build based on what people actually need.
Not sure what the number means or how to apply it? Ask — we're happy to explain in plain terms.
Pool service companies, content creators, or educators — reach out and tell us what you have in mind.
Gallons vs litres, pounds vs kilograms — if the units are confusing, ask and we'll clarify which to use.
Questions about what we collect, how long we keep it, or how to request deletion. We keep it simple.
