# LispApp vs Chitz

The clearest difference is update cadence: Chitz at every 3 days against LispApp's every 11 days. LispApp's advantage is iOS requirement (13.0 vs 15.1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. LispApp sells 1 in-app purchase, starting at $34.99 per month and Chitz sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

LispApp ships an update every 11 days, Chitz every 3 days. Both last shipped on September 28, 2026.
