# QUAPIX Lite vs 魚定規

The clearest difference is in-app purchases: QUAPIX Lite at none against 魚定規's 1. QUAPIX Lite also leads on review sentiment (36% vs 20%). 魚定規's advantage is ads (none vs shown) and iOS requirement (7.1 vs 12.0). On price and device support there is nothing between them.

Both are free to download. 魚定規 sells 1 one-off in-app purchase. QUAPIX Lite asks for nothing beyond the download.
