Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
A new welcome flow — start planning your day right after signing up. Home now puts today first, so your time blocks are the first thing you see.
• New calendar events stay inside the app, so personal plans no longer leak into a Google Calendar you share with work or family
• Share a note by link — anyone can read it without signing in
• Type @ in a note to link another note
• Fixed notes being overwritten with older text when several windows were open
• Fixed the task screen failing to open, and changes from other devices arriving late
• Tasks now sync only what changed instead of the whole list, so everything feels faster
