I use Ara Spends almost every day. The app loads quickly and doesn't share my data with third parties. The app shows my spending habits with simple charts that I can understand.
Ara Spends can be set in a snap: choose your country/currency, and you're good to go! All the necessary features to master your personal budget and spending are available out of the box.
Some parts are locked behind in-app purchases, but they're free to use for 7 days.
