# Interchange vs WoWo Comics

The clearest difference is monetization model: WoWo Comics at free with in-app purchases against Interchange's subscription. Interchange's advantage is ads (none vs shown) and ratings volume (212 vs 17). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Interchange sells 9 in-app purchases, starting at $2.49 per month and WoWo Comics sells 7 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
