OCD Toolkit is a free collection of tools designed to help you manage OCD β built by someone who deals with it too. No subscriptions. No paywalls. Just tools that help. What's inside: Log - Track your compulsions and triggers over time. Logging what's happening is one of the most powerful first steps in understanding your OCD patterns β and gives you something real to discuss with your therapist. Breathe - A guided 4-7-8 breathing exercise to help calm your nervous system when anxiety spikes. Simple, proven, and always available. Resist - A compulsion resistance timer. When the urge to carry out a compulsion hits, Resist helps you sit with that discomfort and watch it pass β one of the core principles of ERP therapy. Remind - A collection of insight cards covering OCD, intrusive thoughts, and recovery. Swipe through them or get one at random when you need a reminder that you're not alone and recovery is possible. Checked? - A verification tool designed to help you break the checking cycle. Get the reassurance that the urge is asking for β once β and then move on. OCD Toolkit isn't a replacement for professional support. If you're struggling, please reach out to a therapist or OCD specialist. This app is a companion for the work you're already doing β not a substitute for it.

Verdict
The clearest difference is in-app purchases: OCD Toolkit at none against Blink's 1. Blink's advantage is iOS requirement (17.0 vs 26.4). On price, ads and device support there is nothing between them.
