# ProMeter vs 咖啡札记

The clearest difference is update cadence: 咖啡札记 at weekly against ProMeter's every 3 weeks. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. ProMeter sells 1 one-off in-app purchase and 咖啡札记 sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

ProMeter ships an update every 3 weeks, 咖啡札记 weekly. Both last shipped on October 30, 2026.
