# Spermy vs circloO

The clearest difference is ads: Spermy at none against circloO's shown. Spermy also leads on update cadence (every 2 weeks vs every 2 months) and iOS requirement (7.0 vs 10). circloO's advantage is ratings volume (2.4K vs 339). On price, rating, review sentiment and in-app purchases there is nothing between them.

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