While the analyser works similarly (enough) to its web-based counterpart, there is one setting the mobile keyboard needs desperately: an option to change tone and formality.I’m not saying that this keyboard is rubbish; it actually can be really helpful — the keyword being ‘can’. If you’re a student or pretty much anyone who have to deal with formal writing, then this app could help you spot those small, and otherwise invisible, grammatical oversights in your texts.That being said, the strict enforcement of ‘formality’ can become an issue. For example: if I’m chatting with my friends on Twitter, my expected tone could be described as ‘friendly’, ‘casual’, and ‘informal’.Being overly-formal in an otherwise informal setting could create a communication barrier between the speaker (you) and their subjects (the people you’re talking to). In other words, you may be seen as ‘inaccessible’ or ‘intimidating’.This can also become a problem if you’re working with fiction. The over-emphasis on ‘formal’ language rules may turn a fun little romance story into a monotonic essay about two people having a shared amorous connection that ends up in an archaic ceremony that chains them together in ‘holy matrimony’ — actually, never mind. I would love to read that essay.This keyboard should allow us to change how ‘formal’ its checks should aim for. Because, guess what, we don’t ALWAYS communicate in a serious school/work/business environment. The web version has that option already, so why shouldn’t the keyboard have it, too?(BTW, if you have Premium, you may also see some amusing synonym suggestions for ‘commonly-used’ words.)
