HTReminder

Pool & Hot Tub Water Testing

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

Keep track of your hot tub or pool water. HTReminder is a water testing app that uses AI to read your test strips, keeps a log of every test, and reminds you when maintenance is due. Just snap a photo of your test strip and HTReminder reads pH, chlorine, bromine, alkalinity, and hardness levels. Check the readings, fix any value by hand, and save the test. KEY FEATURES • AI Test Strip Scanner — Point your camera at a used test strip and get readings in seconds. Works with common multi-pad test strips; you can always enter values by hand. • Chemical Suggestions — Based on your readings, your water volume and the products you choose, HTReminder suggests amounts to consider. Always follow the directions on your product's label. • Spa & Pool Maintenance Reminders — Set schedules for water testing, filter cleaning, water changes, and shock treatments. Get a notification when a task is due. • Water Chemistry History — Track your pH, chlorine, bromine, alkalinity, and calcium hardness over time. See trends and catch problems before they get expensive. • Multiple Hot Tubs & Pools — Manage water chemistry for your hot tub, swimming pool, spa, or all of them. Each gets its own history, chemical inventory, and maintenance reminders. • Chemical Inventory — Track what pool and spa chemicals you have on hand so you know what to buy before your next water test. WORKS WITH: • Hot tubs and spas (chlorine or bromine) • Swimming pools (above ground and in-ground) • Swim spas and plunge pools • Saltwater pools and hot tubs PERFECT FOR: • Hot tub owners who want an easy log of their water tests • Pool owners tired of squinting at test strip color charts • New hot tub or pool owners learning water maintenance • Pool service professionals managing multiple clients SUBSCRIPTION INFORMATION HTReminder offers multiple auto-renewing subscription tiers (Consumer and Professional, monthly and annual plans).
