# Nanotechnology vs ChemBioCalc

The clearest difference is ads: Nanotechnology at none against ChemBioCalc's shown. ChemBioCalc's advantage is update cadence (every 4 days vs every 2 months) and iOS requirement (15.1 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Nanotechnology sells 6 in-app purchases, starting at $9.99 per month and ChemBioCalc sells 4 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Nanotechnology ships an update every 2 months, ChemBioCalc every 4 days. Both last shipped on October 28, 2026.
