Hey hey,
I stumbled on this free app that can be of great help when it comes to remembering setups, instrument placement, settings, cogs or whatever. 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 etc. You can view the chain like a multimedia slide.
You could make a "how to" assemble a certain part (cogs?) for others to use or you can reverse the chain so you know how to put it back together. You could also record a nice route you took.
Another nice option is that you can share your chain with others. And soon you can upload them to the internet for the rest of the world to use.
You can find it here
www.chainr.com. The app is tested by the apple store.
Any feedback or comments are welcome!
