## What is Pool Service Log & Calculator?

Thank you for using PoolCalcs and for taking pool care seriously. Careful pool owners and service professionals deserve a tool that respects their time. PoolCalcs keeps practical calculations and organized service history together for quicker work and better records.

Calculate pool volume without hunting through formulas or repeating conversions. Enter the measurements you have, choose American or Metric units, and review clear results for everyday planning.

Pool shape calculators include:

- Circular pools
- Rectangular pools
- Elliptical and oval pools
- Square pools
- Free form pools
- Bean shaped pools

Useful conversion and water tools include:

- Area and distance conversion
- US, Imperial, and metric volume conversion
- Flow rate conversion
- Pressure conversion
- Fahrenheit, Celsius, and Kelvin conversion
- Rainwater collection estimates
- Langelier Saturation Index estimates

Build a dependable pool service log instead of relying on loose notes, old photos, or memory. Create a profile for each pool and keep its water tests, chemical treatments, maintenance work, and saved calculations attached to the correct property.

Each pool profile can store:

- Pool name and estimated capacity
- Shape and surface type
- Sanitizer and filter type
- Pump type and climate region
- Notes for equipment, access, or seasonal details

Record water chemistry readings that matter during routine care:

- Free chlorine and combined chlorine
- pH and total alkalinity
- Calcium hardness
- Cyanuric acid
- Salt level
- Water temperature
- Test date and notes

Keep a chemical treatment history with the product name, dose, unit, reason, notes, and optional before and after readings. It becomes easier to answer practical questions such as what was added after heavy rain, how much chlorine was used last time, or whether a treatment produced the result you expected.

Track maintenance work in the same pool record:

- Filter cleaning and backwashing
- Pressure readings before and after service
- Equipment checks and part replacement notes
- Opening, closing, and seasonal tasks
- Cleaning and follow-up reminders

The Records view is made for quick work on site:

- Search saved pools by name
- Sort records by name or type
- Choose ascending or descending order
- Review record totals at a glance
- Open a pool to see its full history
- Save calculator scenarios for later comparison

Protect and reuse your data with Import & Export tools:

- Create a restorable JSON backup
- Import a compatible PoolCalcs backup
- Export records as spreadsheet-ready CSV
- Share an export through the standard iOS share sheet
- Review what is included before moving your data

The built-in reference library keeps helpful pool chemistry guidance close by. Search saved topics from sources including CDC, EPA, USGS, and PubChem, then open the original publication when you want more detail.

Settings provide practical app-wide controls:

- Select American or Metric units for supported calculators
- Check the App Store for an available update
- Clear saved calculator inputs without deleting pool records
- Reach support, privacy information, and terms

The free plan keeps essential calculators available and provides limited record saving. PoolCalcs Pro unlocks every pool calculator and unlimited pool profiles, water tests, treatments, maintenance entries, and saved scenarios. Monthly and lifetime purchase options are available, with restore support through the App Store.

For monthly subscriptions:
Monthly Pro is a 1-month auto-renewable subscription.
Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

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.

### 7.2 — 2026-05-28

This update turns the app into a much stronger day-to-day pool tool. The calculator side is still fast, but now the records side does real work too, and the free plan is easier to understand at a glance.

New in this version:

- Added a full Pool Records area for keeping ongoing pool history in the app instead of scattered notes.
- Added pool profiles so you can save the pool name, gallons, shape, surface type, sanitizer type, filter type, pump type, climate region, and notes.
- Added water test logging for free chlorine, combined chlorine, pH, alkalinity, calcium hardness, cyanuric acid, salt, temperature, date, and notes.
- Added treatment records for chemical additions, dosage, units, reasons, notes, and linked before and after readings.
- Added maintenance logs for service tasks, filter pressure before and after, and general care notes.
- Added saved calculations so important results can be kept with the rest of the pool record.

The records workflow is much better now:

- Create a pool profile once and come back to it whenever you need it.
- Open a saved pool to reach its own record hub.
- Keep tests, treatments, maintenance entries, and saved calculations tied to the right pool.
- Review counts and history without digging through old notes.
- Make the app useful after the math is done, not just during the first setup.

The free plan is clearer and more useful:

- Circular Pool and Rectangular Pool stay available on the free plan.
- Those two calculators now show a visible remaining-today badge in the calculator list.
- Pool records are no longer hidden behind a blank wall on the free tier.
- The app now tracks daily free usage for the included tools in a way that is easier to follow.

Record saving on the free tier is now easier to understand:

- Free plan includes 1 new record save per day.
- You can use that daily save for a pool profile, water test, treatment, maintenance entry, or saved calculation.
- The app now stops extra free saves at the actual add and save points instead of leaving the limit unclear.
- Upgrade prompts appear when the daily limit is reached, right where the next step would happen.
- Pro keeps the records side open for unlimited ongoing use.

The upgrade flow is better too:

- The paywall now includes clearer privacy and terms links.
- Subscription wording is more direct about monthly billing and cancellation.
- Lifetime purchase messaging now does a better job explaining that it does not cancel an active monthly subscription by itself.
- Settings now includes a cleaner Pro status area.
- Support contact from the app now opens a real email flow instead of only sending you to a contact page.

Practical improvements you will notice:

- It is easier to save a pool and come back later.
- It is easier to attach the next reading to the right pool.
- It is easier to compare what happened before and after a treatment.
- It is easier to keep maintenance notes that are actually worth reading later.

Good update for:

- Pool owners who want fewer scattered notes
- Service techs who want a cleaner history on site
- Vacation property managers keeping track of multiple pools
- Anyone who uses a pool volume calculator often enough to be tired of retyping the same details
- Anyone who wants a pool care app that keeps both the numbers and the story behind them

If you have been using the app mainly for quick calculations, this release adds the missing half: a real place to keep the water readings, chemical work, maintenance trail, and saved scenarios that make those numbers useful later.
