Pool Calculator & Care Log
Water Tests & Service Logs
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Thanks for taking great care of your pool. Get quick volume calculations, clear water test logs, and organized treatment and maintenance records, all in one simple place.
Thank you for using Pool Calcs and for the care you put into every pool you look after. Your attention to readings, cleaning, and follow-up makes a difference. Pool Calcs puts the numbers and the work history in one place, whether you care for your own pool or serve customers.
Start with the size of the pool. Enter measurements in American or Metric units and get a volume estimate you can use when planning water care, equipment work, or a service visit.
Pool volume calculators cover:
- Circular and rectangular pools
- Square pools
- Elliptical and oval pools
- Free form and bean shaped pools
Keep the everyday math close at hand:
- Convert area, distance, volume, flow rate, and pressure
- Switch between Fahrenheit, Celsius, and Kelvin
- Estimate rainwater collection
- Review a Langelier Saturation Index estimate for water balance
A pool profile gives each property its own history. Record its capacity, shape, surface, sanitizer, filter, pump, climate, and notes. Search and sort your pool list when you need to find a detail on site.
Build a useful water test log:
- Save free and combined chlorine readings
- Record pH, total alkalinity, and calcium hardness
- Track cyanuric acid, salt, and water temperature
- Keep the test date and notes with each entry
When you add a product, save its name, amount, unit, reason, and optional before and after readings. A chemical dose record helps you see what you used last time, while a maintenance log keeps cleaning, filter work, pressure checks, equipment notes, and seasonal tasks with the pool they belong to. Save calculator results for later, too.
For service work, the Service tab helps you move from today's list to a finished visit:
- See scheduled, due, and unfinished visits
- Open an address in Maps when one is saved
- Record water readings, treatments, tasks, notes, and photos
- Keep equipment details and repair or upgrade estimates
- Follow up on recommendations awaiting a decision
- Share a service report with your business details
Record the service plan, visit date, and work completed. For each visit, you can enter revenue and direct labor or chemical costs to see a simple contribution estimate. Keep those numbers beside the notes for the job, ready to review before the next visit.
Create a customer once and assign multiple pools to them. The customer’s name, email, and phone stay shared, while each pool keeps its own service address and history. If you choose to allow Contacts access, you can import customer details from Apple Contacts and confirm updates before replacing saved fields. Your pool records remain available without Contacts access.
Insights and Care Habits help you review the work over time:
- Review water chemistry trends and compare readings across pools
- See filter pressure and treatment trends
- Check off daily care habits and follow your progress
- Review saved tests, treatments, visits, and maintenance in one pool history
Pool Calcs is a practical companion to your own testing and judgment. Follow product directions and local guidance when making chemical or maintenance decisions. With measurements, service notes, and pool history together, the next visit starts with the facts you already recorded.

PoolCalcs does not replace professional testing, product directions, local codes, or qualified service. It gives careful pool owners and professionals a clear workspace for calculations and records, helping good decisions start with better information.
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.
