I am trying to phrase the value proposition for my productivity app, which aims to help people get going with activities they easily give up on. At the moment it reads like this:
Thank you for installing %appname%.
We hope it helps you to get more productive with the things you want to do.
It felt wrong (I wasn't sure whether to use productive with something or productive at something), so I checked Google and a few dictionaries only to find no evidence of using productive with an object (except phrases like “be productive at home/work”). So I wonder if it's an appropriate use at all.
I would rephrase it with “get [more] successful at the things you want to do”, but this feels like a promise too strong: the fact that the user gets more engaged with the activity doesn't guarantee they find success at it. And I'd avoid the word 'engaged' as being too formal.
