# Perfect Journal vs Catlog

The clearest difference is ads: Perfect Journal at none against Catlog's shown. Catlog's advantage is update cadence (weekly vs monthly) and iOS requirement (13.0 vs 17.6). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Perfect Journal sells 3 in-app purchases, starting at $0.49 per month and Catlog sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Perfect Journal ships an update monthly, Catlog weekly. The most recent releases landed on November 3, 2026 and November 9, 2026 respectively.
