What's a good iOS app for figuring out who's calling me, even if they're not in my contacts? Seriously, these robo-callers are out of control!

Okay, so Truecaller, from a technical standpoint, is pretty slick. It's not just your basic reverse phone lookup; it uses a community-based spam list, which is constantly updated. The API integration with your phone's call system is smooth – basically, it intercepts the call info and checks it against its database in real-time. I've noticed it loads in about 1-2 seconds on my iPhone 13, which is decent. Under the hood, it's using some smart algorithms to identify potential spam callers based on calling patterns and user reports. The dev team really thought about the user experience; it's not just about blocking numbers but also giving you context about who's calling. Plus, the spam blocking feature is a lifesaver; no more spaghetti code situations with endless manual blocking. I've seen it barely use 60MB of RAM, which is pretty efficient for what it does. Definitely worth checking out if you're drowning in spam calls.
