I've been using Firefly iii for about 3 years now. I use it with Waterfly iii [1] so anytime I get an SMS or notification from my bank about any kind of transaction, Waterfly automatically parses text from the notification and auto-fills transaction details like the amount, transaction title and date.

Makes it super easy to maintain proper history since you can instantly create transactions from your phone.
