Spendle is an iOS application for smart budgeting. Spendle analyzes your purchase history to determine "bad spending habits" and your location to alert you via text when you approach a bad spending habit area.
For example, say you've ordered at a coffee shop every day for the past month. If you are on your way to that coffee shop, Spendle will send you a text telling you how much you've spent there and encourage you to reevaluate that habit.
Spendle uses its own API to communicate the web service with the iOS application. For more information on Spendle's API, check out docs.md.
Spendle uses Twilio to send customized SMS messages to users.
