Verdict
The clearest difference is rating: CTS ActivityLab at 5.0 against Watchletic's 4.3. CTS ActivityLab also leads on ads (none vs shown) and update cadence (every 2 days vs every 2 weeks). Watchletic's advantage is ratings volume (29 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Watchletic sells 2 in-app purchases, starting at $3.99 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.
CTS ActivityLab holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Watchletic has 29 ratings behind it against 1, so its average is the more settled of the two.
Watchletic ships an update every 2 weeks, CTS ActivityLab every 2 days. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
