WaterMinder

Staying hydrated is an important part of your physical wellbeing. For years, I’ve been using WaterMinder to track my hydration intake. Recently I’ve started using a smart water bottle with its own app (more on that in a bit), but I continue to use WaterMinder for manually logging liquids, including those that aren’t water.
Like most of the apps on this list, WaterMinder supports HealthKit. It also lets you set up your favorite beverages (and custom ones, too) and assigns a hydration score to different drinks. You can easily add to your daily intake using the widget or Siri; and, it supports Apple’s new Shortcuts app.
The app is extremely customizable. In addition to custom drinks and Siri Shortcuts, WaterMinder lets you change the appearance of the app and even the icon. You can set a goal or let the app calculate a goal for you. You can even view—and customize—a cool visualization of how much water (or other drinks) you drank.
WaterMinder is $4.99. I know that may seem like a lot for an app, but I’m a big believer in paying for apps rather than dealing with ads or in-app purchases. The app is well-designed and regularly updated, and it’s a small price to pay for staying healthy and obtaining your goals. Purchase WaterMinder from the App Store.
