# Keep vs 跑步机助手

The clearest difference is monetization model: Keep at freemium against 跑步机助手's subscription. Keep also leads on ratings volume (17K vs 3). 跑步机助手's advantage is ads (none vs shown). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Keep sells 12 in-app purchases, starting at $2.99 per month and 跑步机助手 sells 4 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for Keep against 4.7 for 跑步机助手. That said, the two scores are not equally well evidenced: Keep has 17K ratings behind it against 3, so its average is the more settled of the two.

Keep ships an update weekly, 跑步机助手 fortnightly. The most recent releases landed on October 15, 2026 and September 14, 2026 respectively.
