Rekount is one of the better looking and super functional personal budgeting apps I've seen. There is a one-time IAP for $10 and the app can be tried out for free. I think this one will be useful to many who simply want to maintain a record of basic spending/income and budget accordingly.
Dawn is an elegantly minimal calendar app that aims to revolutionize calendars with integrated to-dos, reminders, and subtasks. It's the calendar for you to manage entire days.
