Where Patterns has been, and where it is going.

A proper light mode, made with the same care as the dark one. Choose System, Light, or Dark in Settings and the whole app follows.

Patterns is on the Play Store. Same app, same tools, and the same promise that nothing you write leaves your device unless you choose to export it.

The self-check is no longer a one-off number. Every result you save builds a history you can follow across months, and the scores go into the PDF you can take to a therapist.

Contamination, checking, harm and taboo thoughts, relationship doubt, and just-right. Each one is a few weeks of exposures written for that theme, instead of a blank ladder to fill in yourself. Part of Pro.

Every screen that can stop you saving was rewritten, so the message reads like a nudge rather than a telling-off. Nobody needs that from an app about OCD.

If an entry went onto the wrong date, open that day, tap the bin, and confirm. The day goes blank again and nothing else is touched.

Instead of swiping through a slideshow, the app asks what would help right now and takes you straight there. You can start delaying a compulsion, or writing, within a minute of opening it.

When you finish that first exercise, there is a quiet screen to notice how it went instead of being dropped back at a menu. The app also waits to ask about notifications until it has a reason to.

Today shows what you have done the moment you do it, and suggests one next step, so you never open Patterns and wonder where to start.

Pro has come back down to $19.99 from $39.99. Prices vary by country, and your app store always shows yours. Still one payment, still lifetime, still no subscription. If you already own Pro, nothing changes and you pay nothing again.

Somewhere to write, one day at a time, with bold, italics, and lists when you need them. Search back through old entries, and set a gentle daily reminder if that helps.

Write down an obsession or a compulsion as it happens, and rate how distressing it was from 0 to 10. It is the same scale therapists use in ERP, so your notes travel well.

Delay a compulsion and see what happens to the urge. Guided practice for checking, reassurance seeking, googling, rumination, and washing. With Pro, build a fear ladder, keep scripts, loop tapes, and images next to it, follow a week-by-week program, ride out an urge, sit with not knowing, and test what OCD swears will happen.

The Y-BOCS, the questionnaire clinicians use to gauge how heavy OCD is right now. Take it whenever you want a read on whether things are shifting.

Breathing, grounding, and other coping strategies, a toolkit for when things spike, and space to decide in advance what you will do the next time a trigger lands, so you are not deciding while flooded.

Charts that turn scattered entries into something you can actually see. You can save it all as a PDF to bring to a therapist, only if you want to.

Your journal and OCD records stay on your device. No account or cloud sync. Lock the app behind Face ID or your passcode, and keep your own backup as a single file. Optional anonymous feature-use analytics stay off unless you turn them on, and never include personal OCD content.

Pay once, keep it. No subscription, no renewal. If you change phones, restore it from Settings.
