# STEP vs K

The clearest difference is review sentiment: STEP at 50% against K's 0%. STEP also leads on in-app purchases (none vs 8) and ads (none vs shown). K's advantage is rating (4.4 vs 2.3) and update cadence (every 2 weeks vs every 3 months). On price and device support there is nothing between them.

Both are free to download. K sells 8 in-app purchases, starting at $1.99 per 3 months. STEP asks for nothing beyond the download.

K holds the better App Store score, 4.4 against 2.3. That said, the two scores are not equally well evidenced: K has 142 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 50% of STEP's written reviews are positive against 0% of K's, so the app with the better star average is not the one people write more warmly about.

STEP ships an update every 3 months, K every 2 weeks. The most recent releases landed on October 10, 2026 and October 15, 2026 respectively.
