Update: All three versions of Pool Advisor - Pool Advisor (free, with ads), Pool Advisor (99 cents, with no ads), and Pool Advisor Pro - are now available in the Marketplace!
Now you can manage multiple pools, keeping track of chemical checks, inventory, and reminders for each pool. Or if you're running a pool company and have your own inventory, you can keep track of all your inventory in one place.
Use the Select Active Pool page to select a pool you are working on or add a pool.
And you can change how the Inventory is managed in the Multi Pool Settings
I've got some more things I will add, including being able to export the data, set a primary pool, and email test results to a pool owner. If you have any other ideas to make this a better product, please let me know!
