# Cronometer vs ProFx LLC

The clearest difference is ads: ProFx LLC at none against Cronometer's shown. ProFx LLC also leads on rating (5.0 vs 4.8). Cronometer's advantage is ratings volume (99K vs 6) and update cadence (weekly vs monthly). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Cronometer sells 11 in-app purchases, starting at $10.99 per month and ProFx LLC sells 1 in-app purchase, starting at $299.99 per month. Whichever you choose, the download price is not the number that matters.

ProFx LLC holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Cronometer has 99K ratings behind it against 6, so its average is the more settled of the two.

Cronometer ships an update weekly, ProFx LLC monthly. The most recent releases landed on October 19, 2026 and October 2, 2026 respectively.
