We've used Octopus.do at our agency to estimate a few projects. It's simple so it likely won't be of much use for estimating complex projects but anything that's a website is infinitely easier to estimate and explain with this tool.
Pros:Easy to create plain-as-day design/development estimates that are tied to an actual sitemap
Cons:None that I've yet encountered
Keep the good work and please, keep it simple. The whole estimate part is becoming relevant. Great job!!!!
Pros:- The "block" system within the pages is game changer. - Interface is fast, minimalist and ergonomic.
Cons:- I didn't find the way to duplicate a page. - Only one map structure is possible
Simplicity is the ultimate sophistication.
Pros:Fresh and promising product, one app to manage multiple tasks and entire project. It’s brilliant!
Cons:No cons
I use it instead of old price proposal template and so far all clients liked the approach. Thumbs up!
Pros:Easy sharing and neat look
Cons:No cross-links
Good app with future
Pros:Great tool for for developers and their customers
Cons:For me its cool
