Why I built Patterns

I want to be upfront about something before you read another word: I am not a therapist, a doctor, or a researcher. I am a person with OCD who got tired of fighting the same loop with sticky notes and half-finished spreadsheets, and decided to build something better. Patterns is that something.

The tool I kept looking for

For years my "system" was chaos. A notes app full of intrusive thoughts I was too embarrassed to reread. A reminder to "not check" that I ignored. A vague memory of what my distress felt like last Tuesday that my brain happily rewrote into something worse. When I finally started ERP - exposure and response prevention - my therapist asked me to track my compulsions and rate my anxiety. I wanted to. I just did not have anywhere calm to do it.

Every app I tried felt wrong. Some wanted an account and my email before they would show me anything. Some sold my kind of vulnerability back to me as a subscription with a countdown timer. Most were built for "wellness" in the abstract and had never heard the words obsession and compulsion used the way people with OCD use them. I wanted something that spoke my language and then got out of the way.

What OCD taught me about design

OCD is, among other cruelties, a demand for certainty. So I knew that whatever I built could not become another thing to do perfectly. If logging a compulsion turned into its own little ritual - the right tags, the right time, the exactly correct wording - I would have just handed my OCD a new toy. So Patterns is deliberately low-stakes. You can write two words or two paragraphs. You can rate your distress and move on. Nothing punishes you for a missed day.

I also knew it had to be private in a way I could feel. Not "we take privacy seriously" in a footer - actually private. So everything you write in Patterns stays on your device. No account, no cloud, no one on the other end. I made that choice for myself first, because I could not be honest in a journal I did not trust.

Built around the therapy that worked

The reason Patterns is shaped the way it is - a journal, an OCD tracker, a distress scale, a compulsion delay tool, and a whole recovery toolkit - is that those are the moves ERP asks of you. Name the thought. Notice the urge. Rate the distress. Delay the compulsion. Sit with the wave until it passes. Look back and see that it did. I did not invent any of that; I just tried to make it a little less lonely to do at 2am.

I am not trying to be your therapist. I am trying to be the notebook that is already open when you need it.

For everyone else in the loop

If you have OCD, you already know the specific exhaustion of it - the way a single thought can eat an afternoon. I built Patterns for that person, because I am that person. It is free to download and use, the core is open source, and the Pro tools exist so I can keep working on it without turning your worst moments into an ad slot.

You do not have to do this perfectly. That is sort of the whole point. You just have to keep showing up, and it helps to have somewhere calm to do it.
