# CID vs Dioscope

The clearest difference is ads: Dioscope at none against CID's shown. CID's advantage is update cadence (monthly vs every 4 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. CID sells 1 one-off in-app purchase and Dioscope sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

CID ships an update monthly, Dioscope every 4 months. The most recent releases landed on November 3, 2026 and October 9, 2026 respectively.
