Verdict

The call

The clearest difference is ads: Polar Flow at none against Pace Calculator's shown. Polar Flow also leads on rating (4.6 vs 4.3) and ratings volume (50K vs 39). Pace Calculator's advantage is update cadence (every 5 days vs monthly) and review sentiment (68% vs 50%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Pace Calculator sells 1 one-off in-app purchase and Polar Flow sells 1 in-app purchase, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Polar Flow holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Polar Flow has 50K ratings behind it against 39, so its average is the more settled of the two. Written reviews complicate that: 68% of Pace Calculator's written reviews are positive against 50% of Polar Flow's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Pace Calculator ships an update every 5 days, Polar Flow monthly. The most recent releases landed on October 23, 2026 and October 27, 2026 respectively.
