# Instancy vs Computer Science Dictionary

The clearest difference is update cadence: Instancy at every 2 months against Computer Science Dictionary's every 16 months. Computer Science Dictionary's advantage is iOS requirement (13.0 vs 17.6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Instancy sells 13 in-app purchases, starting at $12.00 per month and Computer Science Dictionary sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Instancy ships an update every 2 months, Computer Science Dictionary every 16 months. The most recent releases landed on October 10, 2026 and September 22, 2026 respectively.
