4 Ways to Get Drinking Water Reminders on Apple Watch

While the Apple Watch has many health-centric features, it lacks any built-in option to remind you to drink water. However, we do have third-party apps that send you alerts to stay hydrated when required. In this article, let’s look at three free apps to enable drinking water reminders on your Apple Watch.

However, given the busy schedule, it’s normal to forget to drink water altogether. This is where the drink water reminder apps come to the rescue. Here are free apps and shortcuts to get notified for drinking enough water or other liquids like coffee or juices to keep you hydrated and energized.
