# ZERO vs KYUFO

The clearest difference is in-app purchases: ZERO at none against KYUFO's 3. ZERO also leads on review sentiment (29% vs 5%) and iOS requirement (12.0 vs 17.0). KYUFO's advantage is update cadence (every 3 days vs every 6 weeks) and ratings volume (128 vs 12). On price, rating, ads and device support there is nothing between them.

Both are free to download. KYUFO sells 3 in-app purchases, starting at $6.99 per 7 days. ZERO asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 2.4 for ZERO against 2.6 for KYUFO. That said, the two scores are not equally well evidenced: KYUFO has 128 ratings behind it against 12, so its average is the more settled of the two. Written reviews are what separate them: 29% of ZERO's written reviews are positive against 5% of KYUFO's.

ZERO ships an update every 6 weeks, KYUFO every 3 days. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
