If you’re having a hard time keeping track of your aquarium maintenance activities and you don’t want to keep paper notes on the tasks you performed and when you performed them, then you can look to your phone for help. If you own a smartphone (iOS or Android based), then chances are you have access to any one of a number of aquarium related apps that help you do the tracking and even set reminders. If you can’t find an app that suites your needs, there are several native apps that can handle all of the tracking as well. For example, the iPhone has a Notes app and a Reminders app, but of which can be used in conjunction with each other to keep your aquarium maintenance routine on track. Because these are two apps that you have to enter and input data into, we recommend aquarium logging apps like aquaPlanner.
