# BitQ vs Lemma

The clearest difference is update cadence: BitQ at every 2 weeks against Lemma's every 4 months. BitQ also leads on iOS requirement (15.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. BitQ sells 3 in-app purchases, starting at $1.99 per month and Lemma sells 1 in-app purchase, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

BitQ ships an update every 2 weeks, Lemma every 4 months. The most recent releases landed on October 2, 2026 and October 10, 2026 respectively.
