THE PRODUCT

The problem
and the approach.

The challenge

Remembering water intake and the start of a fasting session requires repeated small actions. Separate notes and timers make it harder to see what was actually recorded over a day or week. The interface needs quick entries, editable history and clear timer controls without turning tracking into a complicated task.

The approach

Combine water presets and custom amounts with configurable fasting plans, pause/end controls and local reminders. Daily records feed progress charts, history and locally prepared reports, so the overview and exported summary come from the same tracking data. Milliliters and US fluid ounces are input/display choices. The product supports tracking and reflection without promising health outcomes.

Who it helps

People who want a simple record of their water intake and chosen fasting schedule, with personal goals and device reminders.

A typical workflow

  1. Set a personal water goal and choose a fasting plan if desired.
  2. Log water or start a fasting session, with optional locally scheduled reminders.
  3. Review history and progress, then build and preview a PDF report for a chosen period.
