WHAT IS IMPRESSION JOURNAL? Impression Journal is a fast, flexible way to capture the small stuff — a person you just met, a bird or flower you spotted, an idea passing through your head — and tie it to a place and a moment in time. Create an Impression with a name, a short description, and hashtags, and Impression Journal automatically timestamps and locates it for you. Prefer to talk? Just ask Siri for a "Quick Impression" to jot something down instantly, or a step-by-step "New Impression" to add notes and tags. More features: * Add a photo to any Impression * File Impressions into folders * Browse everything by Recents, Tags, Places, or Search * See all your Impressions plotted on a map * Track repeat encounters with an Impression as a timeline of sightings * Add a widget to your home screen to see nearby Impressions, filtered by folder and hashtags * Set up custom notifications to alert you when Impressions are nearby (full version only) * Everything syncs automatically over iCloud * Companion Apple Watch app allows you to capture a thought without pulling out your phone Whether you're putting names to faces at a conference, remembering the code for your storage unit, or just catching an idea before it slips away, Impression Journal keeps a searchable, location-aware record of the little things you'd otherwise forget.
