The best way to make sure that all of our pool maintenance tasks are done is to keep a good record of them. While many phone apps can track your progress, it all boils down to whether you're religious in entering the values into your phone. Most of the time though, we don't bring our phones out with us poolside when we're doing the tasks and you know what they say, out of sight, out of mind.
The best way to go about this is to go old-school! We've prepared a printable maintenance checklist so you can just stick it on a clipboard (don't forget the pen!) and place it somewhere visible so you can simply grab it and go during your pool maintenance tasks.
