Your attention to water testing matters, and this app helps you keep readings, customer details, and service visits organized. Whether you maintain your own spa or look after several properties, bring your water balance calculator and service log together. Enter measured values, check the Langelier Saturation Index, and keep a useful record for your next visit. CHECK POOL AND SPA WATER BALANCE - Calculate LSI from measured pH, water temperature, calcium hardness, total alkalinity, and total dissolved solids. - See the calculated saturation pH and a result category. - Review whether readings suggest a scale or corrosion tendency. - Work in Fahrenheit or Celsius and convert the entered temperature when switching units. - Find the formula, measurements, and result ranges in Help. KEEP READINGS YOU CAN FIND AGAIN - Save measurements under reusable pool, spa, and property names. - Record dates and notes about water condition, treatments, or follow-up work. - Search saved history by site, result category, or notes. - Sort readings, correct saved inputs, and recalculate after an edit. - Duplicate a record for another visit. - Review a reading beside the records list on wider iPad layouts. PLAN AND RECORD SERVICE VISITS - Schedule visits for a saved pool or spa site. - Add a technician, visit status, and completed-work checklist. - Record actual chemical actions, service observations, and customer notes. - Link a saved water reading or enter fresh measurements for the visit. - Preview a service report before saving. - Keep an unfinished new visit as a local draft. - Note the next service or retest date and book a separate visit when ready. KEEP CUSTOMERS AND SITES CONNECTED - Save customer names, companies, phone numbers, emails, addresses, and notes. - Add customers manually or choose contacts to copy from Apple Contacts. - Link several sites to one customer and give each site its own address. - Keep local contact edits separate from device Contacts. - Find mapped sites using their address or a linked customer's address. - Search the site list even when a property still needs an address.
