Pool Brain vs SplashLens comparison

Pool Brain vs SplashLens: They're Not Competing (Here's Why)

📅 November 22, 2025⏱ 5 min read

Pool service technicians searching for "Pool Brain vs SplashLens" are often trying to decide between two tools — but the comparison is a bit like asking "should I use Google Maps or a wrench?" They're designed for fundamentally different jobs. Understanding what each does (and doesn't do) saves you from buying the wrong tool for the wrong problem.

Pool Brain: Route Management and Business Operations

Pool Brain is a software-as-a-service platform for pool service companies. Its job is to run your business: scheduling stops, logging service data, sending customer reports, managing invoices, and organizing your route. It's the operational backbone of a professional pool service operation.

What Pool Brain handles:

What Pool Brain doesn't do: It doesn't calculate how much chemical to add. You enter what you added — it doesn't tell you what to add. That calculation happens in your head, on a calculator, or in a chemistry tool.

Pool Brain costs approximately $69/month for a solo operator, scaling up with additional technicians. It's a monthly subscription business tool.

SplashLens: Chemistry Calculations and Field Reference

SplashLens is a free, offline progressive web app (PWA) built for pool service technicians who need accurate chemistry calculations and field reference in the field. It's not a business management tool — it's a technical tool.

What SplashLens handles:

What SplashLens doesn't do: It doesn't schedule your route, send customer invoices, or manage your billing. It's a field chemistry tool, not a CRM or route management platform.

SplashLens is completely free — no subscription, no account required, no premium tier.

Why Most Techs Should Use Both

The tools serve different phases of the service visit:

A common workflow: test water → open SplashLens → enter current readings and pool volume → get dosing recommendation → add chemicals → switch to Pool Brain → log what you added → close stop → customer gets automated report. The entire workflow costs you $69/month (Pool Brain) + $0 (SplashLens).

Who Needs What

If you're a solo tech under 20 accounts who currently manages your route on paper or in a spreadsheet, you probably don't need Pool Brain yet. Start with SplashLens for your chemistry and add Pool Brain when your admin time justifies a $69/month subscription.

If you're already using Pool Brain and not using a chemistry calculator, you're likely either doing the math in your head (error-prone) or estimating doses (margin leak and inconsistent results). Add SplashLens. It's free and will improve the accuracy of every stop on your route.

If you're comparing both and trying to pick one — you've identified the wrong question. They're not alternatives. They're complements. Use both.
