ONE STEP EACH DAY A short lesson to understand what is going on, then an exercise that matches your level. There is no calendar to keep up with. The next day opens once you have practised.

You rate your anxiety before and after each session to follow your progress. WHAT CALMENA INCLUDES • A 14-day journey with 9 short lessons • Nearly 200 exposure items across 4 levels • More than 130 everyday challenges, from the easiest to the most demanding • Breathing and relaxation exercises, available at any time • A journal to note your mood, your anxiety and your thoughts • Tracking of the safety behaviours you want to reduce • Statistics to see how far you have come • A quick help button for difficult moments A STRUCTURED APPROACH The exercises are inspired by CBT literature. Sources are listed in the app. FREE TRIAL AND SUBSCRIPTION Your first session is open without a subscription. To follow the whole journey, the annual subscription starts with 14 free days, then costs €19.99 per year. Nothing is charged during the trial. The subscription renews every year unless you cancel at least 24 hours before the renewal date, from your App Store account settings. YOUR DATA Your data belongs to you.

OpenStep is a self-guided therapeutic app for people living with OCD. Built on CBT (Cognitive Behavioral Therapy). 22-Step Exposure Ladder Your recovery starts where you are. A graduated system takes you from standing at your door to riding public transport and visiting a cinema — at your own pace. Each step includes instructions, duration guidance, and encouragement. AI-Powered Cognitive Reframing Anxiety lies. OpenStep uses AI to identify cognitive distortions like catastrophizing, fortune telling, and all-or-nothing thinking. Catch the patterns your mind uses to keep you stuck - a core skill in CBT for OCD. Daily Affirmations 7 categories crafted for the unique challenges of agoraphobia — brave days, setback days, being far from home, navigating crowds, and more. Structured Practice Sessions Every practice follows a 5-phase model: Plan → Stay → Notice → Return → Reflect. Track anxiety before and after, record what your mind predicted versus what actually happened, and watch evidence of your progress grow. Growth Journal Capture reflections, track anxiety patterns, and build a personal record of recovery. Daily Check-Ins A gentle morning notification invites you to set your focus — keeping your CBT practice consistent and momentum steady. Why OpenStep? • Evidence-based CBT approach to OCD • Self-paced — no therapist required • Warm, calming design — not clinical • AI-assisted thought analysis • 49+ handcrafted affirmations • Journaling and progress tracking Terms of Use: https://www.faravaree-lab.com/terms-of-use

Verdict
The clearest difference is ads: Calmena at none against Open Step's shown. Open Step's advantage is update cadence (every 5 days vs monthly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
