# Keep vs 极速健身

The clearest difference is ads: 极速健身 at none against Keep's shown. 极速健身 also leads on review sentiment (70% vs 53%). Keep's advantage is device support (4 vs 2). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Keep sells 12 in-app purchases, starting at $2.99 per month and 极速健身 sells 10 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

Keep ships an update weekly, 极速健身 every 2 weeks. The most recent releases landed on October 14, 2026 and October 8, 2026 respectively.
