# Molekula vs CalcWheel

The clearest difference is ads: CalcWheel at none against Molekula's shown. Molekula's advantage is ratings volume (6 vs 1). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. Molekula sells 1 one-off in-app purchase and CalcWheel sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Molekula against 5.0 for CalcWheel. That said, the two scores are not equally well evidenced: Molekula has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Molekula ships an update every 2 weeks, CalcWheel every 9 days. The most recent releases landed on October 24, 2026 and October 6, 2026 respectively.
