Present your iCal calendar events and reminders right on your desktop with this stunning calendar viewer. Blotter renders your whole week as a part of your wallpaper. It is beautifully discreet yet only a glance away. Blotter also makes it a snap to add a new event or reminder to your calendar. Use the always present menu bar icon, or configure global keyboard shortcuts which work from within any application on your Mac.

Did you ever mark something in your calendar only to forget to check the calendar? No more. With your week right before you, you always know if you can make a meeting on Tuesday or if you’ll be able to go home early on Friday.

• Keep your existing calendar. Blotter will tie directly into your Mac OS X iCal calendar instead of recreating it.
• Quickly add a new event or a new reminder.
• Keep things snappy. Blotter uses very little memory and processing power.
• Optionally view the next 7 days instead of a regular week.
• Quickly customize what to display, what to hide and how much space to give each section.

Also works with Google Calendar. See our support site for more information.

Note that Blotter does not support calendar editing beyond adding events and reminders.

What I was looking for

Bakari C

I was a little hesitant, based on the negative reviews, to purchase this application. But so far it is pretty much what I was looking for. I have it parked on my second monitor, where it stays faded and in the background of other apps. I have the hotkey for the calendar mapped to a Dragon Dictate voice command, so I can simply call it up when I need to view it above other opened windows. I also have it linked to a Keyboard Maestro macro so that when my computer is awakened, this calendar comes to forefront after 10 seconds.

I like how it syncs with iCloud calendar, and allows for adding events from the menubar. Though I do say to-do manager, it’s very useful to get a overview of scheduled events without having to open the regular calendar app on my to-do manager.

I’m glad it’s still working. I’m sure the developers could much more with it, but for now it seems to be working okay.

Helped me with my Time Management!


I am not sure how many college students use this, but I love being organized. I finally realized my agenda was not working when I missed an interview. So I decided to look up some great calendar apps for the computer and came across this one. There were many negative reviews, but I decided to take the chance. This is LITERALLY life changing. I have the Google Calender app on my phone, so when I schedule an appointment or plan I enter it immediately onto Google Calendar and it syncs to Blotter on my macbook. For people who may be having trouble opening the system preferences for the app, there’s a calender symbol near the clock on the right, top hand side of the computer. For $10, I am sure I would have been hesitate to get this, but I had a giftcard. :) Either way it has been a very good investment. Hope the company only continues to improve the app.

Definitely not worth $10


Got this looking for a replacement for Fantastical, which had been crashing on me when I tried to edit or add events. This app is pretty limited in what it can do and totally unsuited for what I need.

You can’t interact with your events or reminders. It’s nice to have my “to do” list on my calendar but if I have to go into the Reminders app to mark them completed anyway then it kind of defeats the purpose.

The ability to add events and reminders is pretty limited. For instance, in Fantastical I can type something like “Do Something every Tuesday 11am” and it will create a recurring event on Tuesdays at 11am called “Do Something”. Blotter doesn’t pick up on any of these sorts of things. If I entered the same text into Blotter it doesn’t know what day or time I want and just uses all of that text as the event title and I still have to set the day and time manually and if I want it to be recurring I have to edit it in another app to specify that.

It also doesn’t pull any of my delegated calendars from work.

Basically, the only way to access this calendar is by binding it to a key. You can’t put it in the dock so the only options appear to be to bind it to a key or to go into the menu bar item and select bring to front, but either way if you try to interact with the calendar at all it closes itself.

I like the design, but functionally it’s pretty limited, especially for $10.
