# Mumu Calculator vs FormulaPad

The clearest difference is ads: FormulaPad at none against Mumu Calculator's shown. Mumu Calculator's advantage is update cadence (every 3 weeks vs every 2 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Mumu Calculator sells 1 one-off in-app purchase and FormulaPad sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Mumu Calculator ships an update every 3 weeks, FormulaPad every 2 months. Both last shipped on October 31, 2026.
