Been using Lithium Pro for a couple months now. It’s basically an app that gives you extra features for the free Lithium reading app. Pretty solid if you’re into ebooks and digital reading.
Here’s what you can do with Lithium Pro: There’s cloud sync so you can keep your stuff backed up and synced across your devices. And it’s got custom themes too – you can change the colors and backgrounds. Oh, and there are more highlight colors which is kind of nice. More features coming later too.
Look, if you use Lithium a lot, Lithium Pro is worth checking out. It’s not perfect – the syncing is a bit buggy sometimes – but overall it does the job and makes the reading experience a bit better. Worth the few bucks in my opinion.
