# POSTOJ vs 3

The clearest difference is ads: 3 at none against POSTOJ's shown. On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. POSTOJ sells 12 in-app purchases, starting at $8.99 per month and 3 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
