What's New in Pool Calculator & Care Log

7.6

September 28, 2026

Thank you for using Pool Calcs. The care you bring to each pool, from a quick water test to a full service visit, deserves tools that keep up. This update puts service work up front and gives your records more room to tell the whole story. Plan the day from the new Service tab: - Open Today's Service List to see scheduled, due, and unfinished visits. - Start a visit from the list and keep the work tied to the right pool. - Open a saved customer address in Maps when you need directions. - Find customers, recommendation follow-up, and report branding in the same place. Keep better notes while you work: - Add water readings, chemical treatments, tasks, and customer notes to a service visit. - Use quick entry choices for common readings, products, units, reasons, and tasks. - Add photos when they help explain a condition or completed work. - Use Help, Share, and Reset controls at the top of a visit. - Share a service report with your chosen title, business name, contact details, technician, and footer. Customer records have more useful choices: - Share one customer record across multiple pools, with separate pool addresses and histories. - Add a pool from a customer’s page or choose an existing customer when editing a pool. - Create a customer in Pool Calcs without giving Contacts access. - Import a customer from the Apple contacts you choose to share. - Choose Import Updates to copy the latest details from an imported contact. - Review a confirmation before an update replaces saved contact details. - Unlink a contact without deleting the customer in Pool Calcs. Pool Records now follows the life of each property: - Add a service plan and keep visit reports with the pool profile. - Record equipment details, including familiar or custom categories and models. - Create repair and upgrade estimates, then track recommendations awaiting a decision. - Keep water tests, chemical dose records, maintenance, and saved calculations together. - Search and sort pools to get back to the right history more quickly. There is more to learn from the work you already record: - Pool Insights shows water chemistry trends, service activity, and pool comparisons over time. - Review filter pressure changes and how treatments relate to later chlorine readings. - Use Care Habits for daily checks, streaks, and milestones within the app. - Read saved calculation values in plain labels instead of a block of data. Backups and exports are easier to find in More: - Save a full backup that includes supported pool and service records. - Import a compatible full backup when you need to bring records into the app. - Export spreadsheet files for individual record types. - Share a backup or export through the options available on your device. - Read clearer descriptions before choosing a backup or export action. The rest of the app has been tidied up, too: - Pools, Customers, Service, and More now have clear places in the main tab bar. - Search the calculator list to find a pool shape or converter faster. - Choose System, Light, or Dark appearance in Settings. - Switch supported calculators between American and Metric units. - Check for an App Store update when it suits you. - Find shorter Help sections and the Pool Reference inside More. Small details matter during a busy day. Converter choices stay with the values you entered, temperatures below absolute zero no longer show a result, and the pool screens give more space to the information you came to see. The free plan also explains its daily limits more clearly, while Pro keeps the full calculator set and unlimited new record saves available to subscribers and lifetime owners. Thank you again for using Pool Calcs and for keeping careful records. Whether you are checking one backyard pool or working through a service route, this release is meant to help you find the next useful detail and move on with the job.
