# VirPulse vs CTS ActivityLab

The clearest difference is rating: CTS ActivityLab at 5.0 against VirPulse's 4.3. VirPulse's advantage is ratings volume (6 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. VirPulse sells 3 in-app purchases, starting at $0.99 per month and CTS ActivityLab sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
