Our methodology

To determine which expense tracker apps offer the best user experience, CNBC Select analyzed over a dozen apps offered by the top companies in this market and looked at their pricing, features, user reviews and ratings.

We narrowed down our ranking by only considering apps that primarily focus on expenses, come with low (or no) cost to sign up, are easy to use and can be accessed on multiple devices so are accessible and compatible for most.

The five apps we selected for this ranking are either free, offer a free version or have a free trial for users to test out before signing up.

All of the apps in our round-up have a sizable number of user reviews and high ratings. The apps on this list have tens of thousands of reviews in the App Store (for iOS) and on Google Play (for Android) combined, as well as a rating over 4 stars (out of 5) on either platform.

Other factors we looked at included apps’ security features, user customization and educational tools offered.
