# NOBOOK Lab vs ChemLab

The clearest difference is ads: NOBOOK Lab at none against ChemLab's shown. NOBOOK Lab also leads on iOS requirement (13.0 vs 15.1). ChemLab's advantage is update cadence (weekly vs monthly). On price, in-app purchases and device support there is nothing between them.

Both are free to download. NOBOOK Lab sells 8 one-off in-app purchases and ChemLab sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

NOBOOK Lab ships an update monthly, ChemLab weekly. The most recent releases landed on October 30, 2026 and November 9, 2026 respectively.
