# ProMeter vs 开喝 kaihe

ProMeter and 开喝 kaihe are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. ProMeter sells 1 one-off in-app purchase and 开喝 kaihe sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ProMeter ships an update every 3 weeks, 开喝 kaihe monthly. The most recent releases landed on September 19, 2026 and September 8, 2026 respectively.
