# Stepz vs Duffy

The clearest difference is monetization model: Duffy at free with in-app purchases against Stepz's subscription. Duffy also leads on ads (none vs shown) and rating (4.7 vs 4.5). Stepz's advantage is update cadence (weekly vs every 5 months) and ratings volume (33K vs 757). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Stepz sells 10 in-app purchases, starting at $2.99 per 7 days and Duffy sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Duffy holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Stepz has 33K ratings behind it against 757, so its average is the more settled of the two. Written reviews point the same way: 75% of Stepz's written reviews are positive against 84% of Duffy's.

Stepz ships an update weekly, Duffy every 5 months. The most recent releases landed on September 25, 2026 and September 23, 2026 respectively.
