I am working on a currency converter, that I would really like to get some feedback on, however I don't want to break the rules, therefore I ask in advance before posting it. Am I allowed to ask for adjustment advice on this forum? Currently it is only available online, however I wish to make it into an app for people to use. The thought is, that the app should update once a day and thereby allowing the user to get the most of it even though it is offline. I look forward to reading your response.
