People struggle to track and build a consistent water habit

People who want to drink more water ask for free tools, reminders, and ways to log intake with very little effort. Existing options may feel too expensive or require a separate, fiddly app; one plasma donor specifically values custom drink entries and the ability to record fluid loss. The signals point to demand for simpler tracking and encouragement, but don’t establish how common these needs are.

For people trying to drink more water, including plasma donors. Mentioned from Oct 2024 to Apr 2026 on Bluesky and Stack Exchange.

  1. I’m a plasma donor and currently use Waterllama on iOS to make sure I stay on top of hydration on and around the days I give plasma - specifically, the premium version has a feature where one can both define custom drinks and assign them hydration values, including negative values, so I register a donation as a “drink”…

  2. does anyone have any recommendations for like a habit tracker thing for ios would be great if it was really effortless to use, like only one tap to track (mainly wanting to track water intake so *probably* could use a separate app but that kinda defeats the purpose for me)
