Aqua Mind

Aqua Mind is a water log you fill in yourself. It starts empty. You add each drink as you have it, and every number in the app is built from what you entered. Tap Log on the Today screen, pick a container and a size in millilitres, and the drink is saved with the time. The ring on Today fills toward the daily goal you set in Settings, and the two chips beside it show that goal and how much is left. Under the ring sits a row of one-tap buttons built from your own container list, so a glass you drink several times a day takes a single tap. The Log tab holds every drink you have ever saved, grouped under day headings with the newest day on top. Each row shows the time, the size and the container. Tap a row to edit it, or use the delete icon to remove it. Containers are yours to manage. Add a name and a default size, rename one, delete one. The list you build is exactly what the quick-add buttons and the add dialog offer. Stats draws a bar chart of the last seven days from your saved drinks and works out the total, the daily average, your best day and how many of those seven days reached the goal. With no data yet it says so rather than showing invented numbers. Settings holds the daily goal, a switch between millilitres and cups, a list of planned drink times you can add to and remove, and Clear all data behind a confirmation. The planned drink times are a personal schedule shown inside the app. Aqua Mind does not send notifications and will not alert you. Everything is stored on your device. There is no account, no sign-in, no sync, no ads and no internet access at all — the app has no network permission.
