Fluidics

Fluidics is an app for tracking your daily water intake.

If that sounds at all complicated, don’t worry, it’s not! Fluidics is designed to be as simple to use as possible.

The center of the app is your four most-used amounts - tap and hold until the circle fills, and you’re done! Tap quickly if you want to change one; they can be in fluid ounces, milliliters, or liters. As you drink water, you’ll see the screen fill up - when there’s no more white on screen, you’ve met your goal for the day!

Two screenshots. The first shows the Quick Add screen of the app: a label, reading '0 fl oz' at the top, and below it, four buttons arranged in a grid, with '8', '12', '16', and '24' in them. The second is the same screen, with the label changed to read '16 fl oz'. The background of the screen is partially filled with blue.

Those same quick add options also appear in the widget - just tap and hold to quickly add from anywhere you can access the widget. Change the quick add amount or unit in the app, and it’ll change in the widget, as well.

Drank a different amount than usual, but don’t want to change the Quick Add just for that? No problem! Just swipe right and you can enter any amount you’d like. Tap ‘add’ and you’re done!

If you need to change any settings, it’s just as easy - swipe left to get back to the Quick Add page, and then left again to get to the settings. From there, you can adjust the view settings, tweak the numbers Fluidics uses to calculate your daily goal, and check our privacy policy.

What’s the business model?

If you’re anything like me, you’re a bit suspicious of free apps - where’s the sense in giving something away for free, right?

No need to worry: the core features of the app are free. In the future, additional (“pro”) features will be available for a low-cost annual subscription.
