## What is Cinder?

Journal with AI — 100% private.

A journal that understands you. AI generates personalized prompts, tracks your mood, and spots patterns — all processed entirely on your device.

AI-POWERED WRITING PROMPTS
Never stare at a blank page. AI generates personalized prompts based on your mood, past entries, and what's happening in your life.

MOOD TRACKING
Log your mood with every entry. Premium unlocks mood trend, frequency, and writing-time charts to spot patterns effortlessly.

PRIVATE BY DESIGN
Your journal never leaves your device. No cloud sync, no servers, no data collection. Just you and your thoughts.

REFLECTION INSIGHTS (Premium)
AI surfaces themes and growth patterns from your entries, plus encouragement notes as your journaling streak grows.

100% PRIVATE — ON-DEVICE AI
All AI features are powered by Apple Intelligence and run entirely on your device. Your data is never uploaded to any server, never processed in the cloud, and never shared with anyone. What happens on your device stays on your device.

No account required. No sign-up. No tracking. No ads in the free tier.

PREMIUM
