# Elementium vs Chemist Calc

The clearest difference is update cadence: Elementium at every 3 weeks against Chemist Calc's every 9 months. Elementium also leads on ratings volume (576 vs 1). Chemist Calc's advantage is rating (5.0 vs 4.6) and monetization model (free vs freemium). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Elementium sells 9 in-app purchases, starting at $1.99 per month and Chemist Calc sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
