You know the problem: You study with JW Library® on different devices - and in the end, you have two versions, that you can’t easily combine anymore. With the Library Merger this is a thing of the past! The Library Merger allows you to quickly and easily combine two JW Library® backups into one. Simply open both backups in the app (you can even send them via AirDrop). The app will merge them into one. If it finds a conflict (like two bookmarks at the same place, or two markings that overlap), you can choose which version to keep. In the end, you have one merged backup which you can easily restore on your devices. The process - if done regularly - literally takes you seconds! Library Merger is still in its early stages and is being actively developed. The code is open source and can be found on GitHub. If you found a bug or have suggestions, feel free to contact me.

Verdict

The call

The clearest difference is in-app purchases: Library Merger at none against Kitwise's 1. Library Merger also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). Kitwise's advantage is update cadence (every 2 weeks vs every 2 months). On price and ads there is nothing between them.
