A great free tool that might be a better experience than your answer is [LibreOffice Draw](https://www.libreoffice.org/discover/draw/). It's free, they support iOS, and it's very intuitive to use for simple to complex diagrams. It's basically the open-source version of Microsoft Visio, which is widely used in the business world for things like this. You could also pay for Visio, but its price tag probably won't appeal to you.

For a small fee ($5/month, might vary in your region) you can also get [Office 365](http://www.office.com), which includes a huge suite of very useful software. Two programs in particular might help you if Draw isn't your thing: PowerPoint and OneNote

[PowerPoint](http://www.powerpoint.com) is the old familiar standby, easy to use, lots of built-in shapes and text options, diagram tools, etc. It's a little better at handling text than Draw is, so it could be worth a look if you plan to use lengthy descriptions.

[OneNote](http://www.onenote.com) is one of my favorite office programs and might suit you if you like a more hand-drawn feel. It's set up like a notebook, with different sections and pages that expand as-needed, so you can organize your notes very easily. You can also literally draw on it if you use a touchscreen, or even just with a mouse, so you can keep your dashed lines and custom shapes. Things you draw get converted into objects, so you can select and drag them around, erase bits of them, etc. It also supports super-easy hyperlinking and text/image insertion, if you want to reference external sources or add visuals. I can't recommend this one enough for just general use if you like taking notes, especially if you use a touchscreen and stylus.
