Knowing Your Audience
We mentioned that fantastic support websites often help create devoted app fans, while making your app more accessible to a larger variety of people. We really enjoy Tapbots' support page, and recommend that you check it out when you have a chance.

You'll find quickly that a large percentage of your user base could be based in countries that don't speak English, and if this happens, do you have a plan in place to translate your app? Services from companies like PhraseApp and Tethras make translation easy.
