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.

SMPW Scheduler is the fastest way to build a volunteer rotation. Add names, pick a start and end time, choose an interval, and tap Shuffle. You get a clean, color-coded schedule you can share as an image in one tap. No accounts, no logins, no syncing services to configure — open the app and go. FEATURES • Fast schedule generation — enter volunteers, set a time window, shuffle. • Multiple locations — assign volunteers across two or more spots in a single schedule. • Flexible time intervals — 15, 20, 30, 60 minutes, or a custom length. • Optional date header and scriptural point line. • Color-coded assignments for easy reading. • Dark mode. • One-tap share — sends the schedule as a PNG through Messages, Mail, or any other app. Recipients don't need the app installed. • Save the image directly to Photos. • Works fully offline. PRIVACY SMPW Scheduler does not collect personal information. No accounts, no analytics, no ads, no tracking. Every schedule you build stays on your device. The only network call the app ever makes is to increment a global counter that tracks how many schedules have been generated across all users — no names, no device info, no schedule contents.
