Okay, so what's a solid Android app for making international calls without breaking the bank and, ideally, offers some data I can actually track?

Alright, so I've been digging into BOSS Revolution, and from a data perspective, it's statistically satisfying. I can see where my money's going with international calls and mobile top-ups. The graphs are actually readable, unlike some of the garbage I've seen. It's almost like Tableau, but for normal humans. Plus, I can export my call history to CSV in under 10 seconds – data nerd approved! I haven't fully explored the API capabilities yet, but the fact that they likely exist makes me happy. Finally, goodbye to Excel hell for trying to track international call costs. Clean datasets are a beautiful thing, and this app seems to deliver on that front. The 4.7 rating seems legit.
