# Avira Mobile Security vs ParallelCalculator

The clearest difference is ads: Avira Mobile Security at none against ParallelCalculator's shown. Avira Mobile Security also leads on iOS requirement (13.0 vs 15.1). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Avira Mobile Security sells 10 in-app purchases, starting at $1.99 per month and ParallelCalculator sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
