About

resista.

Features
Read full description

Resista. is a fasting and habit tracker built for women with insulin resistance, PCOS, and ADHD who are tired of being lectured, guilted, and handed a calorie counter. No keto required. No calorie counting. WHAT IT DOES Set your fasting window once. The timer runs. The voice stays dry. Log four daily habits with one tap each — protein first, walk after dinner, supplements, evening closer. No food diary. When cravings hit, tap the struggle button. Get a concrete tip, not a pep talk. THE VOICE Resista. treats you like an intelligent adult who's having a moment — not a patient who needs managing. Direct, occasionally sardonic, never sending motivational quotes at 6am. FOR YOUR BRAIN Built for the ADHD brain. No guilt when you miss a day. No streaks that punish you for being human. Contextual nudges at the right moment — not constantly. NOT MEDICAL ADVICE Resista. is a habit and tracking tool, not a medical device. Always consult your doctor about your health.
