RECORD Save body observations alongside mood, food, hydration, notes, and everyday context. Talk Check-In also lets you speak or type what you are noticing, review a structured draft, make corrections, and choose exactly what gets saved. REGULATE Use guided breathing sessions when you want a quiet moment to slow down, reset, or refocus. Adjust breathing timing and keep a history of completed sessions. REFLECT Review Insights based on your own recorded history, explore patterns across time, and use the Reflection Center for daily, weekly, and monthly views.
