# Cudex vs StepChallenge

The clearest difference is in-app purchases: StepChallenge at none against Cudex's 3. StepChallenge also leads on iOS requirement (17.0 vs 26.5). Cudex's advantage is ratings volume (6 vs 1). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Cudex sells 3 in-app purchases, starting at $4.99 per month. StepChallenge asks for nothing beyond the download.

StepChallenge holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Cudex has 6 ratings behind it against 1, so its average is the more settled of the two.

Cudex ships an update weekly, StepChallenge every 4 days. Both last shipped on November 6, 2026.
