Built by a field tech who got tired of fighting his own app in a backyard. WaterMark does everything the big platforms do — without the twelve taps, the tiny text, and the screen you can't read at 2pm in July.
14 days free · no credit card · cancel anytime. Built for pool companies tired of tools made by people who've never tested water.
The big enterprise platforms were designed at a desk, for a desk. Then shrunk onto a phone and handed to someone standing in a wet backyard. It shows.
Bright screens, tiny text built for tablets. Useless in direct sun — which is where pool work happens.
Pool work is a route. Most platforms schedule it like office appointments, ignoring drive time and stop order.
No dosing math. No LSI. No history. The single most important part of the job — and the app does nothing for it.
Screens that don't connect. No memory of where you were. Intense focus required for what should be muscle memory.
You arrive blind. No last reading, no last dose, no note from the tech before you.
Onboarding a new tech means weeks of frustration before they're productive on the app alone.
Log your readings, get exact doses. WaterMark calculates precise chemical amounts for the pool's real volume, computes the Langelier Saturation Index, scores water balance, and tells you straight when there's no chemical fix and you need to dilute. The math a great tech does in their head — done instantly, every time, with no errors in the sun.
Dark by default. High contrast. Big tap targets for wet hands. Readable at 2pm in July, because that's the whole point.
Your stops, in order, one tap to navigate. The next job is always obvious. The route is the home screen.
Arrive and instantly see who serviced it last, their readings, what they added, and their notes. Never walk in blind.
Arrive → readings (pre-filled from last time) → photos → done. No swiping forms away. No losing your place.
Live progress by tech, full service history, every pool's chemistry trend. The whole operation at a glance.
Log everything offline. It syncs the moment you're back in range. Backyards don't always have bars.
Here's what WaterMark does with a pool that's out of balance — instantly, on the spot.
Free Chlorine low (0.8) → Add 84 oz Liquid Chlorine
pH high (7.9) → Add 84 oz Muriatic Acid
Total Alkalinity high (140) → Add 280 oz Muriatic Acid, slowly
Calcium Hardness high (420) → dilution needed, no chemical fix
A straight, factual comparison for pool companies weighing their options.
