SplashMate

Read full description

SplashMate is the pool water tester that won't guess. Scan a test strip or enter your readings by hand, and get clear, on-device results and exact dosing for your pool โ€” no lab, no account required, and no made-up numbers. WON'T GUESS โ€” BY DESIGN If a strip photo is unclear or a pad can't be read reliably, SplashMate tells you instead of inventing a result. You're never handed a chemical dose based on a reading it wasn't sure about. Anything you didn't test shows as "not tested," never as a placeholder number. WORKS WITHOUT AN ACCOUNT Testing, dosing, and your water history run locally on your device. No sign-up is required to test your water. Create an optional account only if you want iCloud sync across your devices. WHAT YOU GET โ€ข Scan Clorox Pool&Spa and AquaDoc test strips, or enter values manually โ€ข On-device analysis of your core water chemistry โ€ข Exact, pool-specific chemical dosing with built-in safety limits โ€ข Support for chlorine, saltwater, bromine, and other common pool types โ€ข Test history and trends so you can see what's actually working NEW: AI POOL HEALTH ASSISTANT (PREMIUM) Ask questions in plain English and get answers tuned to your actual water chemistry โ€” "why does my chlorine keep dropping?", "is it safe to swim yet?", "what order do I add these in?" The assistant is a Premium feature powered by advanced AI. Your readings, dosing, and health score are always calculated on your device โ€” not by AI. FREE โ€ข 15 water tests per month โ€ข Manual entry and on-device dosing โ€ข Test history PREMIUM โ€” $4.99/month or $39.99/year, with a 7-day free trial โ€ข 50 water tests per month โ€ข Photo analysis of test strips โ€ข The AI Pool Health Assistant chat โ€ข Data export for your records or your pool pro PRIVACY โ€ข Test your water with no account and no personal info โ€ข We don't sell your data โ€ข Your questions and chats are never used to train AI models SUBSCRIPTION DETAILS โ€ข Premium: $4.99/month or $39.99/year โ€ข 7-day free trial for new subscribers โ€ข Payment is charged to your Apple ID at confirmation of purchase โ€ข Subscriptions auto-renew unless cancelled at least 24 hours before the current period ends โ€ข Manage or cancel anytime in your Apple ID account settings Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://splashmateapp.com/privacy-policy

Pool Chemical LogBook

Features
Read full description

Keep pool and spa records organized, calculate chemical doses, and prepare PDF logbooks with Pool Chemical LogBook. FREE CALCULATOR Use Chemical Calculator and dosage/correction guidance in Guest mode without creating an account. Enter your volume and measurements, choose US or metric display units, and review water-balance calculations. CHLORINE AND SALT SYSTEMS Choose Chlorine or Salt for each pool or spa. For a salt system, record measured salt in ppm and configure the target and range for your equipment. Review unit-aware salt-addition guidance alongside the existing chemical recommendations. Salt values follow applicable readings into shared history, monthly PDFs and graphs; chlorine readings show salt as not applicable. Older readings without a salt measurement remain unrecorded. TDS and optional ORP readings are also available. ON-DEVICE LOGBOOK โ€” NO REGISTRATION An App Store plan unlocks one on-device facility with up to three pools/spas, saved readings, PDF reports and graphs without an app account. Restore purchases on your supported Apple devices. Records remain on each device; Restore does not recover deleted files. Keep device backups and export important reports. Signing in does not automatically move local records or purchase ownership. PRIVATE CLOUD LOGBOOK Sign in for your account-specific facility logbook, saved reading history, reports and team permissions. Record pH, free and combined chlorine, alkalinity, hardness, cyanuric acid, temperature, flow, filter pressure, initials and notes. FACILITIES AND POOLS/SPAS Start with one protected main facility and one to three pool/spa body slots. Eligible owners can manage additional facilities from Account Info, with each facility's details and bodies grouped together. Archiving an extra facility retains its history and releases its facility credit; restoring it needs available capacity. The main facility remains protected from removal. OWNER-MANAGED TEAM ACCESS In multi-facility accounts, allocated active facilities and distinct active members share the owner's credits. The main facility includes the owner. Pool/spa bodies and facility assignments use no additional credits; inactive invitations use none. Four credits can cover two facilities and two active members, or three facilities and one active member. Owners assign Selected facilities or All current and future active facilities. Members add readings only within their active, assigned and funded access. Edit saved is a separate permission for changing or removing saved readings. Facility and billing management remain owner controls. ORIGINAL WORK AND HISTORY Eligible reading work can be saved offline with its original account, facility, pool/spa and values retained for synchronization. Facility admission, restoration and active allocation changes require a connection. Existing single-facility records and eligible original subscription benefits remain; additional-facility eligibility can require review. REPORTS AND TRENDS Choose the facility and pool/spa for monthly PDF logbooks and chemistry graphs. Select your month or date range and metrics, then export or share the report with its selected labels and scope. SUBSCRIPTIONS Auto-renewing App Store plans unlock the on-device Guest logbook without registration. Optional cloud/team services use account-specific permissions and purchase ownership. Review the selected product's displayed price and terms before purchase. Original packages retain their benefits and pricing; eligible store and manual-invoice coverage remain independent. Manage or cancel through the platform's subscription settings. Account deletion and store subscription cancellation are separate. Follow chemical product labels, allow circulation and retest after treatment.
