You must be 13 or older to use this app. The app is rated 13+ on the App Store.
If you are between 13 and the age of digital consent in your jurisdiction (up to 16 in parts of the EU/EEA), your parent or guardian must review and agree to these terms and our Privacy Policy on your behalf before you use features that process personal data (such as AI report generation).

Nightmare is a self-development app designed to help people understand what's really going on in their lives through journaling and AI-powered insights, then turn that understanding into action.
Features:
The app is free with usage limits to ensure fair access for everyone.
Reports and prompts are generated by artificial intelligence (Anthropic). The AI may make mistakes. Don't rely on AI responses for important decisions without checking them yourself.
Not Therapy or Medical Advice. Nightmare is a self-improvement tool, not therapy or medical advice. Always seek professional help for health-related concerns.
All your personal content (journal entries, tasks, reports, settings) is encrypted and stored on your device. We don't have user accounts or store your data on our servers.
When you generate a report, your journal text and task data is sent through our backend to Anthropic for processing. Anthropic retains this data for up to 30 days for safety purposes, then deletes it. Your data is not used to train AI models.
For full details, see our Privacy Policy.
Use Nightmare for personal, non-commercial self-improvement. Don't use it to:
We may suspend access if you violate these rules.
You own everything you write in the app. We don't claim ownership of your journal entries, tasks, or any content you create.
AI reports are for your personal use. You can share them on social media, but don't sell them or use them to create competing products.
