@Caleb: I recently found myself in need of a portable system for writing while I travel...
The "Notes" app that comes with the iPad is rudimentary to say the least (although I do still use it on occasion).
But for what you want to do, I would totally recomment the Notes Plus app. Thsi is $8.99 from the iPad store and worth every penny. You can type, or use your finger to write cursive (there's also an optional handwriting to text add-in). You can select existing text and change the size, color, font... You can include multiple audio notes on each page. You can draw shapes with your finger and the app will detect whether you are drawing a triangle or a circle or square / rectangle and straignten up the lines and turn it into a resizable object.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
