QUICK ANSWERStart with the tool that matches your immediate input.
Open Water Intake Calculator first when its stated purpose matches the result you need now. Use Wellness Goal Planner only when it solves a separate next task.
This guide is for people using general educational wellness and planning tools. Start with Water Intake Calculator when your immediate task is to open the original Water Intake Calculator and complete the task with a focused browser-based interface. Move to Wellness Goal Planner only when you also need to create a practical wellness goal with guided options and a downloadable result.
The goal is not to run two tools automatically. It is to finish the first narrow task, inspect its result, and then decide whether Wellness Goal Planner solves a genuinely different next step.
Both tools sit in Health & Wellness, but they handle different inputs or outcomes. Keeping those roles separate reduces repeated work and makes verification easier.
