This app is for the purposes of drawing SBOL standard diagrams, without the need of pen & paper or a whiteboard. It should be noted, this app is optimized for iPad screen sizes. To use, you may draw a strand, and then click from the list of available glyphs at the bottom of the canvas to append your glyph to the currently selected strand. To select between strands, click the glove button, and tap your desired strand. To add text, click the text box button and tap on screen to place text in a desired location. If you would like any features added, or require any further information, check out the GitHub link and add to issue tracker. Enjoy!
