# History Timeline vs Date Calculator...

The clearest difference is ads: History Timeline at none against Date Calculator...'s shown. On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. History Timeline sells 3 in-app purchases, starting at $3.99 per 7 days and Date Calculator... sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
