When you complete a reminder, a corresponding activity will be created for you automatically.
For example, if you complete your “Change 5 gallons of water” reminder you will see “Changed 5 gallons” activity in your timeline.
But what about the other way? With the latest update AquaticLog brings you a new ability to add an activity, and if there are any outstanding reminders that match it, they will be completed for you.
This two-way relationship between activities and reminders should make your aquarium maintenance chores more tolerable.
