Punctuation is a code, a series of dots and squiggles that replaces voice tone in your writing. Use the code correctly and your reader will follow your meaning; get it wrong and your reader will be lost, or have to play catch-up as they read.
Many people struggle with punctuation as they write business reports and proposals, minutes, letters or emails. This is often because they were not taught the principles at school, or because it seemed irrelevant and pointless at the time.
Dots and Squiggles is a simple reference app which gives clear guidance on each punctuation mark: choose a mark, see the rules; tap on a rule and get a screen of clear and relevant examples of its use. Written in plain English, it is a model of clarity and simplicity.
