QUICK ANSWERStart with the tool that matches your immediate input.
Open Breathing Exercise Timer first when its stated purpose matches the result you need now. Use Meditation Timer only when it solves a separate next task.
This guide is for people using general educational wellness and planning tools. Start with Breathing Exercise Timer when your immediate task is to use the Breathing Exercise Timer to calculate a transparent estimate and understand the next step. Move to Meditation Timer only when you also need to use the Meditation Timer to calculate a transparent estimate and understand the next step.
The goal is not to run two tools automatically. It is to finish the first narrow task, inspect its result, and then decide whether Meditation Timer 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.
