Intended for use as a tool to aid in taking and recording measurements for tests of PH and Chlorine levels in your pool using any of the commonly available tablet based test kits available designed for visual comparison against a series of printed colours on the test kit.
The app currently allows you to track the change in PH and or Chlorine over the period you test your pool, and the aim is ultimately to add support for reminding you when you should re-test the pool in order to ensure you neither test too often nor not enough to keep the chemicals balanced and your pool algae free.
