iOS: If drawing out your ideas or sketching diagrams on your iPad is the way you brainstorm, Conojo can accommodate you. It's designed to help you whiteboard freely, and it has tools to draw, expand on and export your ideas.
The video above is definitely on the cheesy side, but it's explanatory at least. You get an idea of how the app works, and Conojo has a built-in recording feature that lets you record your brainstorming as you do it. If you're doing an instructional video, Conojo will record it from start to finish, complete with your voice, so you can share it later. If you're designing workflows or charts, you can use backgrounds and templates to get started (many of which are available as template packs via in-app purchase).
Once you're finished, you can save the files locally and share them either via email, Facebook, Dropbox, Evernote and more. We've covered some great tablet drawing apps in the past, but most of those are geared towards art and design. Conojo is a little more amateur-friendly and aimed at people who use their iPads in an office setting.
Hit the link below to give it a whirl — it will set you back $1.99, not including any template packs you may want as well.
