About this app

Patterns is a calm, private space to understand what your mind repeats — and to practice responding to it differently.

What began as a simple OCD journal has grown into a complete, self-guided toolkit grounded in CBT (Cognitive Behavioral Therapy) and ERP (Exposure and Response Prevention) — the approaches most widely used for OCD, anxiety, and intrusive thoughts.

NOTICE YOUR PATTERNS (Free)
• Private, local-first journaling — everything stays on your device
• Log intrusive thoughts, obsessions, compulsions, urges and distress
• Note your responses and the daily context around them
• Watch themes and trends emerge over time
• Protect your entries with an app lock

PRACTICE RESPONDING DIFFERENTLY (Pro)
• Exposure Hierarchy Builder — climb fear ladders one step at a time
• Exposure materials — scripts, loop tapes, images and links
• Urge surfing & response-prevention trackers
• Structured ERP programs & uncertainty training
• Action planner & behavioral experiments
• Recovery metrics & reflection worksheets

WHO IT'S FOR
Patterns was built for OCD, but the same tools help with everyday anxiety, intrusive thoughts, and compulsive habits — anyone who wants to notice their patterns and gently build new responses.

PRIVATE BY DESIGN
Your reflections are personal. Patterns is local-first: your data stays on your device, and an optional app lock keeps it for your eyes only.

SIMPLE, ONE-TIME PRO
Start free with journaling, tracking, and insights. Unlock the full ERP toolkit with a one-time purchase — no subscription, yours for good.

Patterns is a self-guided tool for reflection and skill-building. It is not a diagnosis, medical device, or a replacement for professional care. If you're struggling, please reach out to a qualified professional.

What’s new

Patterns 1.9 adds a full light theme. Choose System, Light, or Dark in Settings and the whole app follows, including Today, Journal, Insights, and every recovery tool.

Advanced Pro tools now introduce themselves where you meet them instead of interrupting you with popups. Purchases are more reliable, with clearer restore results.
Optional anonymous analytics has a clearer consent choice and stays off until you turn it on.

Your journal, exposures, and compulsions stay on your device.
