# Klemy vs TreadCal

The clearest difference is rating: TreadCal at 5.0 against Klemy's 3.9. TreadCal also leads on iOS requirement (18.0 vs 26.0). Klemy's advantage is ratings volume (9 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Klemy sells 6 in-app purchases, starting at $4.99 per month and TreadCal sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

TreadCal holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: Klemy has 9 ratings behind it against 1, so its average is the more settled of the two.

Klemy ships an update every 4 days, TreadCal weekly. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
