# 制选 vs iNC

The clearest difference is ads: iNC at none against 制选's shown. iNC also leads on update cadence (every 6 days vs fortnightly). 制选's advantage is iOS requirement (12.0 vs 16.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. 制选 sells 2 one-off in-app purchases and iNC sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

制选 ships an update fortnightly, iNC every 6 days. The most recent releases landed on October 16, 2026 and October 30, 2026 respectively.
