With Cheddar, your tasks are instantly everywhere. Everything you do with Cheddar pushes to all of your devices, so your world is always in sync. It's really magical to create a task on your iPhone and have it instantly be on your computer without thinking about syncing.
I am a huge fan of TeuxDeux and was using it as my task manager of choice the last two years. Last week I stumbled upon Cheddar. As a Swiss I am almost obliged to love anything that is even remotely related to cheese. The only thing that Cheddar has in common with cheese is the orange UI color which blends in very nicely with the rest of the clean user interface.
Cheddar is a minimalistic task manager that seamlessly syncs your To-Do List with your iPad, iPhone and the web app. There are a couple of things I really like about it. Besides that is more streamlined than «Remember the Milk» you still have the possibility to use #Hashtags. This gives you the possibility to filter your To-Dos. A nice little touch is also the support of Markdown. Markdown makes it very is to style your lists and link to URLs.
The iPad and the iPhone App work like a charm and I am considering switching completely from TeuxDeux over to Cheddar. If you are looking for a fast and sleek task manger, I would give Cheddar a try. If you already gave it a spin, let me know what you think about it.
