What's a good iPhone app for getting lost in a fantasy novel without the app draining my battery in, like, two hours?

Okay, so I've been messing around with Webfic for a few days now, and I'm actually impressed. From a technical standpoint, the battery usage is surprisingly low. I'm talking maybe 10-15% drain per hour on my iPhone 13, which is way better than some other reading apps I've tried. The dev team really thought about optimizing this thing under the hood. It barely uses 60MB of RAM while running. Plus, the app itself is pretty snappy. The API integration seems smooth – basically means it loads pages quickly and doesn't lag when you're flipping through chapters. And let's be real, nobody wants their reading experience interrupted by a dead battery or laggy performance. It's got a 4.3 rating, which seems about right. No more spaghetti code situations here, it seems!
