WoopHealthy

An iOS fitness app built around the science-backed WOOP methodology (Wish, Outcome, Obstacle, Plan) developed by Professor Gabriele Oettingen at NYU.

What is WOOP?

WOOP is a mental strategy grounded in research that helps people achieve goals by combining positive thinking with realistic obstacle identification:

Letter	Step	Description
W	Wish	A meaningful, specific, and feasible fitness goal
O	Outcome	The best possible result of achieving your wish
O	Obstacle	The main inner obstacle that could hold you back
P	Plan	An if-then plan: If [obstacle], then I will [action]
