  • A promoted slot on the AppRater homepage, carrying a Promoted badge.
  • A labelled spot in the weekly email to AppRater subscribers, one promoted app per issue.
  • Stays on the first screen however old the listing is, while new submissions push everything else down.

Patterns: OCD & ERP Journal

OCD

Patterns is a private OCD journal and ERP practice companion built from my lived experience with OCD, research, therapist input, and subsequent user feedback. It helps people record experiences and reflect on patterns while recognizing that tracking itself can sometimes become checking. No account or cloud journal sync is required; personal entries stay on the device. It is a self-help tool, not therapy or diagnosis.
