A friend pointed out a nifty app, called chainr, that can be of great help when it comes to remembering setups, mapping circuits or making a "how to...". It's basically a tool to help you remember multiple actions in a chain. A chain can consist of text, audio recordings, pictures, videos etc. You can view the chain like a multimedia slideshow.
You can edit your chain and share it with others from phone to phone and a way to share with e-mail or over the internet is coming up. They say they are working on a cloud.
The app is free at the moment and I checked it out and thought this could be very nice. Especially when the cloud is up and running.
You can find it here chainr.com. What do you think?
