Free · In-App Purchases · Designed for iPad. Not verified for macOS.

Just opened your hot tub for the season? Get the chemistry right in minutes — log every test, get exact dosing, and never wonder if your water is safe again. Stop guessing. Stop staring at confusing test strips. Stop wasting money on chemicals you didn't need. Hot Tub Buddy turns water care into three simple steps: test, log, dose. Type in your pH, sanitizer, and alkalinity readings — get the exact amount of chemicals to add. No subscriptions. No accounts. No ads. Built for owners of hard-shell spas, inflatable hot tubs (Lay-Z-Spa, Bestway, Intex, MSpa, CleverSpa), and swim spas. KEY FEATURES: SMART WATER QUALITY SCORE See your hot tub's overall health at a glance with our intelligent Water Quality Score. Tap into the full breakdown to understand exactly how your pH, sanitizer, alkalinity, calcium hardness, task compliance, and maintenance status contribute to your score — no guesswork required. GUIDED WATER TESTING & DOSAGE CALCULATOR Forget confusing test strips and chemical maths. Input your readings and Hot Tub Buddy will tell you the precise amount of chemicals to add. Track your results over time with beautiful trend charts and see how your water quality improves. SMART MAINTENANCE SCHEDULER Never miss a filter clean, water change, or chemical treatment again.
