Joined Smarttask today. Great product 
Very enthusiastic about the clarity and possibilities of Smarttask. If you go international, Smarttask can’t ignore German, French, and Spanish.
For our business we really need French. Personally, living in Germany, I think that Smarttask offering would greatly fit with German small and medium businesses.
Localization is nowadays no longer an issue but a chance. Check this website, for example, https://lokalise.com. There are more of that kind out there.
