# ToptiCalc Optics Calculator vs Molecule.dev

The clearest difference is in-app purchases: ToptiCalc Optics Calculator at none against Molecule.dev's 2. ToptiCalc Optics Calculator also leads on ads (none vs shown). Molecule.dev's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 16.6). On price there is nothing between them.

Both are free to download. Molecule.dev sells 2 in-app purchases, starting at $5.99 per month. ToptiCalc Optics Calculator asks for nothing beyond the download.
