I tried several water tracking apps and this is the best. Thank you! ### 2/5 — Meh *2026-02-11, version 1.1* Does this have reminders notifications?? It’s the most simple app I’ve found and I like it but without the reminder notifications to drink water it defeats the purpose of the app ### 5/5 — Finally! *2025-12-22, version 1.1* A water app that not only allows me to track my water intake, but also allows me to change the amount of water on the given buttons. My daily intake goal is 100oz. I was able to change the presets to 10oz and 20oz. Such a simple thing but it made all the difference to me. ### 4/5 — Lovely but… *2025-11-20, version 1.1* I love the simplicity of this app and the lovely simple graphics. Any chance of being able to change the units to ml? That would make it perfect for those of us not in the US. ### 1/5 — Graph feature not working *2025-09-14, version 1.1* Water consumption has been added to the app for a few days, but no information is showing up on the graph. ### 4/5 — Summary *2025-08-07, version 1.1* Suggestion to have a TOTAL of fluid intake of previous days by each day in history when opening ### 5/5 — ❤️ Love this little app *2025-03-22, version 1.1* This is exactly what phone apps were meant to be! Simple, intuitive, useful and free. Hats off to the creator. ### 4/5 — Like but missing an option *2025-03-08, version 1.1* This app is great! I love the fact that it’s free and very easy to use. I’m giving a 4 b/c it does not allow you edit by adding more the previous day. I forgot, woke up, but the option to add was there to edit. ### 4/5 — Free and better than most *2024-11-19, version 1.1* Light weight, simple, and just works. Thanks. @Gregory- any way I can export prior data to HealthKit? Maybe via filesystem? I didn’t have it linked before and am now using HealthKit to review my data. Thanks! ### 5/5 — Love it!!!! *2024-10-11, version 1.1* Designed perfectly ## Frequently asked questions about H2O ### What does H2O - Water Tracker do?
