Bring your books. Lose the clutter.
Nudgr Books does the part of CLZ you actually use — scan, sort, track, lend — and does it fast. Import your whole collection in minutes and feel at home straight away.
I built Nudgr Books because I was a CLZ user myself. I owe CLZ a lot — it's what got my shelves organised in the first place, and it's genuinely powerful. But over the years it grew into something that tries to do everything, and most days I just wanted my shelf: scan, sort, done.
So I built the app I wished I had — the 20% of CLZ I used 100% of the time, made fast and simple. If that's the itch you've been feeling too, you're in the right place.

No. Exporting from CLZ doesn't change a thing in CLZ — the import pulls in a copy. Your CLZ collection stays untouched, so you can try Nudgr Books with nothing to lose.

Absolutely. The import is a copy, not a move, so nothing stops you from running both while you decide.
