About

Stickio

Features
Read full description

Stickio is a calendar for iPhone and iPad that reads like the planner on your desk. Your appointments sit on paper pages, and the little things you need to remember go on top as sticky notes. THE WEEK IS A BOOK Monday to Wednesday on the left page, Thursday to Sunday on the right. Every day shows its appointments at a glance, with a small gauge for how full it is against your working hours. STICKY NOTES FOR EVERYTHING ELSE Stick a note on any day in one of six paper colours: Yellow, Pink, Mint, Sky, Peach or Lilac. Tick it off, turn it into an appointment, or move it to another day. A note stays on its day until you move it. DAY, WEEK AND MONTH • Day: an hour-by-hour page, so you see where the time goes. • Week: the two-page spread, with sticky notes on every day. • Month: one line per day, a grid beside the selected day, or the full grid. Every level scrolls without end into the past and the future, and the month tabs on the edge take you anywhere with your thumb. ADD THINGS WITH ONE PRESS Long-press a day and choose a new appointment or a new sticky note. Set the time, the length, the calendar and a colour, and you're done. ALL YOUR CALENDARS, TOGETHER Connect Google, Outlook and Microsoft 365, iCloud, other CalDAV calendars or a calendar link, and every calendar appears in its own colour. Add as many accounts as you like, side by side. Create, move, edit and delete appointments, answer invitations, and change one or every occurrence of a repeating event. MADE FOR IPAD, TOO On iPad the book opens flat: both pages side by side, two days as facing pages, and the month next to the selected day's agenda. WORKS OFFLINE Stickio keeps your appointments on the device. Changes you make offline are sent as soon as you're back online. PRIVATE BY DESIGN No account with us, no ads, no tracking. Your appointments stay with your calendar provider. Sticky notes, colours and settings sync between your devices through your own iCloud. Nothing is sent to a server of ours. Questions or ideas?
