As a personal finance enthusiast (aka nut), I've tried literally every single financial app on the market. I've been using Monarch since the beta and its easily my favorite.
- The UI is clean and uncluttered (as a UI developer, this is very important to me)
- They support multiple platforms like Android, Web, and iOS
- They add new, awesome features all the time
- They charge you money so they aren't selling your data or cluttering the UI with ads
- And much.. much.. more.
