Rift Notes is the fastest way to get a thought down. Type it like a text. Speak it, transcribed offline. Snap a photo. Every note remembers where you were. Pick up where you left off on iPhone, iPad, or Mac. Privacy-first: no ads, no sign-ups, no subscription, no trackers. Your thoughts, under your control. Three Ways to Capture • Type it like a text. A message-style compose card means thoughts hit paper as fast as you think them. • Speak it. On-device transcription (no internet needed) turns spoken notes into clean, searchable text. • Snap it. 4-up camera attaches photos to text and voice in one note. Built for Thinking • Sync across iPhone, iPad, and Mac via iCloud. Pick up where you left off on any device. • Map your notes. Every note saves its location. Retrace your day, find that door code, or replay the voice memo right on the map where you recorded it. • Focus mode. Distraction-free writing, also great for screenshots. • Themes. Match the vibe with a growing library, including the premium 'Scary Numbers' set. • Rich-text editing renders bold, italics, headers, checklists or numbered lists as you type. • #Hashtag organization and color tags.
