# Keepsmile vs ZENGGE

The clearest difference is ads: ZENGGE at none against Keepsmile's shown. ZENGGE also leads on rating (2.8 vs 2.5) and monetization model (free vs ad-supported). Keepsmile's advantage is update cadence (every 3 weeks vs every 2 months) and ratings volume (4.9K vs 485). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ZENGGE holds the better App Store score, 2.8 against 2.5. That said, the two scores are not equally well evidenced: Keepsmile has 4.9K ratings behind it against 485, so its average is the more settled of the two. Written reviews point the same way: 20% of Keepsmile's written reviews are positive against 31% of ZENGGE's.

Keepsmile ships an update every 3 weeks, ZENGGE every 2 months. The most recent releases landed on October 23, 2026 and October 22, 2026 respectively.
