About Obi-Yomi
Obi-Yomi is a quiet, lightweight calendar for viewing your family's and your own plans side by side, like a single band of time. It is not a do-everything power tool. Its focus is simple: bring plans in, share them, and glance at them. ■ Easy to import Each family member just pastes the shareable address (.ics) of the calendar they already use. Apple Calendar or Google Calendar — paste the URL and their plans line up on the band. No need to retype anything. ■ Import from handwriting, photos, and text (supported devices) Photograph a paper handout or note, paste some text, or write by hand on iPad to create event drafts (automatically on devices with on-device AI; on others you enter them while looking at the recognized text). You always confirm before saving. ■ Switch views lightly • Month (zoom in for a weekly timetable, out for two months) • Timeline (two weeks to two years; sort by person or task — like a Gantt chart for long-term planning) • Day view (overlapping events split into side-by-side columns) See the same plans at the level of detail you want. ■ The same board with family Share the same band with just a code and password. No account required. ■ Availability mode Offer "are you free this Saturday?" with marks right on the schedule. Days when everyone is free turn gold. ■ And more • Tap the schedule to add and edit events • Search across all spaces • Export the schedule (PDF / image / HTML) — to send to friends not on iPhone, to print, and so on • Switch themes to match your mood, from washi paper to Impressionist palettes Obi-Yomi is a tool to easily bring in all sorts of information and view your personal and shared plans at a glance. Note: .ics sync can lag minutes to hours (use it for an overview). AI drafting from handwriting/photos/text runs automatically only on devices that support on-device AI.
