Dreams fade within minutes of waking. Speak yours before it's gone, and watch your own dream world take shape, one night at a time. Dream Journal turns every dream into entries in a personal atlas: the people, places, things and creatures that visit you at night. When something keeps coming back, it becomes a dream sign, your doorway to lucid dreaming. CATCH IT BEFORE IT FADES • Just talk. Your voice is turned into text right on your iPhone • Or type a few words. Half-remembered fragments count too • Tag how it felt, nightmares, and the nights you knew you were dreaming • A gentle morning reminder so you write it down in time BUILD YOUR DREAM ATLAS • Every person, place, thing and creature gets its own page • See how often each one appears and which dreams it came from • Dream Journal recognizes what is already in your atlas when it shows up again • Watch the atlas grow as your recall gets sharper FIND YOUR DREAM SIGNS • Anything that appears three times or more becomes a dream sign • Tonight's dream sign arrives before bed, so you're more likely to notice it in a dream and realize you're dreaming • Pin your own signs and track your lucid dreams ON-DEVICE AI (iPhone with Apple Intelligence) • AI spots the people, places and things in your dream for you • A short reflection on each dream, for self-discovery and fun, not fortune-telling • A weekly look back at your dream world • Runs entirely on your iPhone.

Verdict
The clearest difference is in-app purchases: One at none against Dream Journal's 1. One also leads on ads (none vs shown) and update cadence (every 3 days vs every 2 weeks). On price and device support there is nothing between them.
