Love it.


I've been a happy user of Saisuke for a few years now. Love the copy and paste function.

Update: developers! Please fix the bug that makes it impossible to add notifications

This is by far the best calendar out here, and I’ve tried just about all of them. I would be nice if alarms could be added to events.

Excellent for a busy family!


My wife and I use this to coordinate our work schedules since we work in different cities with busy jobs. It works great for placing both of our schedules on a single calendar that either of us can edit. You do either have to push the sync button or make a change to a calendar to see any changes someone else may have made-it is not quite as automatic as MobileMe.  The calendar is actually better than iCal on the iphone, because you do not need to open a date to see your appointment.  iCal only shows a dot on the calendar to indicate an appointment has been placed there,  SaiSuke allows you to actually see the appointment because the calendar display is larger.  Setup is pretty easy and the website seems to be able to answer most questions. It only takes Saisuke about a second to update after you command it to sync.  Plus, it is free to use unlike the yearly subscription for Apple's program.  After a lot of research, setting up both Saisuke and MobileMe on two iphones and two computers, and using both while watching the programs work on all 4 devices sitting in front of me, I am going to cancel my MobileMe trial subscription before I forget and it starts automatically charging me $99 a year and just use Saisuke.  One last plus to Saisuke- I think it is easier to use than the actual google calendar program on the computer. Well worth the $9.99 especially if you are using this to coordinate the schedules of multiple people!
